Six space-related books you should read (fiction/nonfiction)

Curiosity of man knows no bounds. People are always intrigued by the grandeur of space, but not many people can understand all the complex physical processes. Astrophysics is a branch of science that deals with the properties of heavenly bodies and the physical processes that govern their dynamics. In order to explain theories and scientific laws to the general public, science authors usually use simple language. Sci-fi writers also contribute to this. They often use astrophysical theories and laws in their writings. 

The sci-fi genre has become popular in the past decades. 11 out of 20 top-grossing films made in 2010 were of the same genre. Similarly, in 2020, 29 films were produced in the same genre, making up 20.33% of the market share.  Senior vice president Bruce Nichols of Houghton Mifflin Harcourt publishers said in his podcast: “the entire genre has gone mainstream and some absolutely terrific writers are contributing to it, more than ever before.” Similarly, hundreds of authors have also contributed to the sci-fi genre. 

Here are the top 6 books related to space, astronomy, and astrophysics, both sci-fi and non-fiction, which break down very complicated astrophysical phenomena into an easily understandable language that everyone should read.

Cosmos

Cosmos was written in 1980 by Carl Sagan, a NASA astronomer. He was also the one to design the first mission to Mars. I place this book at the top of the list for several reasons; it has Tons of information is simple to understand and tries to answer a few of the biggest questions in the history of scientific discovery. This book has given me the ability to think differently. Here are a few takeaways from the book:

  • We must never stop learning, questioning and exploring. A whole universe is there to explore. The more one explores, the more one knows about the general understanding of nature at work. Better understanding will lead to better ideas and theories of nature.
  • We must not assume our place as a special one in the universe. We are sitting on a planet revolving around an average-sized star, existing in an average-sized galaxy somewhere in the universe.
  • Aliens may be out there but they may not look like green people with antennas on their heads or laser blasters. There may exist microbial life out there somewhere.

One of my favourite quotes from the book is: 

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”

Recommended 10/10!

Astrophysics for people in a hurry

Astrophysics for people in a hurry

The Cosmos and Astrophysics for people in a hurry are targeted to audiences with mere astrophysical understanding. Astrophysics for people in a hurry is written by Neil Degrasse Tyson, a planetary astrophysicist and director of Hyden planetarium and a host to a famous show at National Geographic, “The Cosmos”.

Nature of space and time, laws of physics, contents of the universe, the space in between galaxies, Earth, planets and planets around other stars, the author explains very complex processes and phenomena in very simple language that even someone with absolutely no background in astronomy can easily understand. Highly recommended to people in a hurry and need a quick overview of the Cosmos.

Score: 8/10.

Theory of everything.

Theory of everything

Stephan Hawking, one of the most brilliant minds of the 21st century, was a mathematician and a theoretical physicist who contributed to understanding gravity, black holes, general relativity and properties of the universe, etc. 

This book is a series of his seven lectures in which he discussed the mysterious black holes, the expanding universe, the origin of the universe and the big bang. He started with the idea of the universe as described by the famous philosopher Aristotle and then the work of Edwin Hubble, who discovered the universe’s expansion. He then discusses the theories on the universe’s origin and the nature of the universe’s most mysterious objects, the black holes.

Hawking further described the formulation of a single detailed equation that defines every physical aspect of the Universe. The author mentioned that this would not be an easy task to perform. At first, partial theories have to be constructed. These theories will then be combined into what he calls “The theory of everything (TOE)’’. However, this merger is yet to happen. TOE is based on two theoretical frameworks: general relativity (GR) and quantum mechanics.

 The former deals with understanding gravity, large-scale structures such as galaxies, galaxy clusters, and regions with high mass content in the universe. Whereas the latter deals with the smallest of scales and objects i.e. atoms and sub-atomic particles. Quantum mechanics and GR have been successfully proven in their respective regimes; however, scientists have yet failed to combine them. Scientists are still trying to find ways to overcome this issue by looking into the underlying theoretical network of quantum mechanics and its components.

The book presents the most complex physical theories and processes in such a simple way that it is easily understandable by a layperson.

Score: 7/10.

Three body problem
Three body problem

Three body problem

My personal favourite Sci-Fi novel, written by Chinese author Cixin Liu, this book made it to the top sellers in the sci-fi genre and received Hugo and Nebula Awards. This is the first of the trilogy. 

The plot revolves around a Chinese astrophysicist whose father, also an astrophysicist, was killed during the Chinese revolution. She established contact with an extraterrestrial life form, who were dealing with their fate as their solar system consisted of 3 suns. Since the three-body problem is chaotic in nature, so are the lives of the alien civilization. Upon receiving the message, the technologically advanced aliens left their system to invade the Earth and save their species, which exists in a stable solar system. 

The book is packed with relatively complex futuristic concepts and requires some good grip on the basics of physics. A point lost for the cold writing style and complex scientific concepts.

Overall score is 7/10.

Hitchhiker's guide to the galaxy
Hitchhiker’s guide to the galaxy

Hitchhiker’s guide to the galaxy

Made it to the BBC’s top 100 books a person should read before dying, this is a sci-fi comedy written by Douglas Adams. The story revolves around “Arthur Dent” whose house was about to be demolished by the road builders. His alien friend, whom he never knew about, tells him that the Earth is about to be destroyed by aliens to establish a Hyperspatial express route. Arthur was saved by his alien friend moments before the Earth was destroyed. 

Don’t panic! A phrase that was written on the cover of Hitchhiker’s Guide to the Galaxy because this keeps intergalactic travellers from panicking. In 2018, SpaceX launched a Tesla Roadster into space with the exact phrase being displayed on its centre screen. Remember it was written in 1979, but if you are a sci-fi enthusiast – packed with comedy – this book will catch your attention.

Score: 7.5/10.

Divided Species
Divided Species

Divided Species

This one receives my special praise as this is the only space-related sci-fi book set in Karachi, Pakistan. My home city! The book covers a story of a young boy from Karachi who ends up meeting extraterrestrials. The outer space beings were on a mission to search for essential mineral resources hidden in the centre of Karachi. 

The story takes place in the city’s famous regions, immersing a reader like me in the book. The book packs suspense, comedy, science fiction and thrill nicely. The best part of the book is that it covers the life of an ordinary person from Karachi, to which I can relate a lot. The book is available in famous bookstores in Pakistan. You can also find it online here link.

I would totally recommend this book with a score of 8/10.

The list, however, doesn’t stop here. These are merely a few books I would recommend to people to read. Especially to those who are looking to read about the cosmos. Some countless authors and books have contributed to this field. Reading about sci-fi allows us to broaden our thinking capacity and provides us with a way to escape from reality.

Moreover, reading non-fiction will increase our knowledge and understanding of the cosmos and the processes and dynamics of space itself. A mix of both fiction and non-fiction will help you understand a lot about the cosmos.

Uncovering the roots: A journey through Pre-Socratic natural philosophy

Uncovering the roots: A journey through Pre-Socratic natural philosophy

The pre-Socratic era in ancient Greece, also known as the Milesian era, was a period of time from around 600 BCE to 400 BCE in which a group of philosophers sought to understand the nature of the world and its origins without relying on traditional religious or mythological explanations. 

Since pre-Socratics were the first philosophers in the Western tradition, their ideas laid the foundation for developing Western philosophy and science.

During this era, several philosophers emerged and constructed their own ideas, each with their own distinctive perspective on the world, and named it “Natural Philosophy”.

Even though most of their work is lost and can only be retrieved through the writings of later times.

Thales: All is water

Thales of Miletus was a Pre-Socratic Philosopher who lived from around 624-546 BCE. He was one of the Seven Sages of Greece and is considered the first Western philosopher. He was known for his famous statement, “All is water,” which he used to explain the origin and nature of the world.

 

According to Thales, water was the basic element of everything, including the earth, air, and fire. All were derived from it.

According to Thales, water was the basic element of everything, including the earth, air, and fire. All were derived from it. He believed that the world was alive and had a soul, and the world’s soul was in the form of water. Thales also attempted to explain natural phenomena such as earthquakes and eclipses in naturalistic terms rather than through myths and legends. 

Moreover, the poet-philosopher Xenophanes asserted Thales’ prediction about the solar eclipse, which became a reason to stop the battle between the king Alyattes of Lydia and Cyaxares of Medes in 585 BCE. 

However, modern-day philosophers did not believe that Thales could foretell the solar eclipse’s position and location.

Anaximander: Cyclical nature of history

Another pre-Socratic philosopher was Anaximander, who was a student of Thales and lived around (610-546 BCE). He was the first one to save his work in written form. He rejected Thales’s idea of “All is water” and proposed an initial formless state called “Apeiron,” which means “Infinite,” which then transformed into two opposite forms like wet and dry or hot and cold. 

Anaximander's concept of the world as an infinite and eternal process planted a seed for maturing the idea of the cyclical nature of history in modern science.

He was also believed to have produced the first map of the world. He also devised an equipment gnomon, a part of the sundial which had been used in China for two thousand years. He contributed in the field of mathematics, geography, and astronomy. 

Furthermore, he believed that life on earth had originated from fish-like creatures that evolved over time.

Anaximander’s concept of the world as an infinite and eternal process planted a seed for maturing the idea of the cyclical nature of history in modern science.

Anaximenes: Air

Anaximenes was a student of Anaximander and lived between (585-525) BCE. He proposed that condensed and expanded air is a reason for the existence of everything. He presented the idea of compressing air, which becomes wind, clouds, and then later when it is more compressed.  This was a  significant theory as it proposed that reality could be measured. 

Later on, his idea of compression and expansion of air was embraced by various philosophers.

Pythagoras: Harmony of the spheres

Pythagoras of Samos, who lived from around 570-497 BCE, is known for his contributions to mathematics and science and his philosophical ideas. He believed in the concept of a cosmic order or “harmony of the spheres,” in which planets and stars moved in a specific pattern, creating a piece of beautiful and harmonious music. 

Pythagoras also believed in the existence of divine intelligence, which he called the "Monad" that governed the Universe.
Pythagoras also believed in the existence of divine intelligence, which he called the “Monad” that governed the Universe.

He also believed in the concept of metempsychosis, or the transmigration of souls; the soul was immortal and could be reincarnated into different life forms. Pythagoras also believed in the existence of divine intelligence, which he called the “Monad” that governed the Universe. He and his followers believed in the concept of mathematical harmony, which they saw as a fundamental principle of the universe.

Heraclitus: As above so, below

Heraclitus of Ephesus, who lived from around 540-480 BCE, was known for his concept of change and the idea of the unity of opposites. He believed that the world was in a constant state of flux and change and everything was in a state of becoming. He famously stated that

 “You cannot step into the same river twice.” 

Heraclitus also believed in the unity of opposites, stating that 

“The way up and the way down are one and the same.”

He presented his theories in the form of riddles. Therefore, he became infamous among people by the name “ the obscure”. He had written his book in an esoteric manner on purpose so that only intelligent ones could understand his write-up and thus prevented himself from criticism by the ordinary men.

Pre-Socratic Atom Theory

Pre-Socratic atomists were a group of philosophers in ancient Greece who believed in the concept of atoms, or indivisible particles that make up all matter. These philosophers predate Socrates, who lived from 469-399 BCE, and their speculation became a base for the atomic theory in Western science.

One of the earliest pre-Socratic atomists was Leucippus, who lived in the 5th century BCE. 

He was believed to have originated the concept of atoms, which he called “indivisible” particles. Leucippus posited that atoms were eternal and indestructible, and they moved in a void or empty space combined with various objects in the world. He also believed that atoms came in different shapes and sizes and combine in different ways to create different substances.

Another Pre-Socratic atomist was Democritus, who lived from 460-370 BCE. He was a student of Leucippus and proceeded with his work on atomic theory. Democritus proposed that atoms were indestructible and eternal, and homogeneous in nature. He believed that the properties of atoms, such as color, taste, and texture, were determined through their arrangements. 

For instance, atoms of water are different than that of Iron.

Democritus also proposed that the universe was infinite and eternal and atoms were constantly moving and colliding to form new objects.

However, another Pre-Socratic philosopher called Zeno challenged his theory of atoms. He asked Democritus to provide an explanation for the void between atoms. He said if there is a void between atoms and the void is a thing, then what is between the atoms of the void, leaving Democritus confounded over his own theory.

Moreover, the pre-Socratic atomists were philosophers and natural scientists, and their ideas significantly influenced modern science’s development. Their concept of atoms as indivisible particles established an essential foundation for the atomic theory, which was further developed by philosophers such as Epicurus and Lucretius in the Hellenistic period, and by scientists such as John Dalton in the 19th century.

In conclusion, the pre-Socratic era was a significant period in Western philosophy and science development. Thales of Miletus, Anaximander, Anaximenes, Pythagoras, Heraclitus, and the Atomists are some of the most prominent figures of this era, each with their own unique perspective about the world.  

However, it is significant to note that the pre-Socratic era was a time of great philosophical thought and political, social, and economic changes in ancient Greece. The philosophers were not isolated from these changes but were also influenced by them.

Hence, these philosophers challenged traditional religious and mythological explanations of the world and proposed new ideas and perspectives on the nature of the world and its origins that continue to influence our understanding of the world today.

Theory of Relativity and Quantum Mechanics

The cosmos is divided into two scales: The very large (Classical) and the very small (Quantum). Attempts to describe these two worlds have been made relentlessly over the last few centuries. Astronomers and physicists alike have presented their understanding of the universe. Newton explained the laws of motion and gravity, and the laws of Thermodynamics explained the energy and heat transfer in a system.

Einstein’s theories of Special and General relativity explained space-time and gravity; Quantum mechanics and the Standard Model of physics explained the fundamental particles and forces of nature; string theory attempted to present a unified theory, and many more.

In a world where time warps and particles dance to the tune of probability lies the intersection of two of the greatest theories in physics: The Theory of Relativity and Quantum Mechanics. Relativity explains the behavior of objects at a classical level, covering gargantuan objects like Quasars to everyday objects like a car, the motion of the planets, the collision of galaxies, and the workings of the ever-expanding Universe. 

Quantum mechanics explains the workings of the Quantum world, from the entanglement of two quantum objects to the fundamental forces of nature and fundamental particles. Without these two theories, our understanding of the Universe would be little to none. Even almost a century later, experiments still prove many different aspects of these two fundamental theories. 

As ground-breaking as these theories might be, physicists have found them to be incompatible with each other. And this conflict has been brewing for almost over a century. 

Many physicists aspire to merge quantum mechanics and general relativity to comprehend the laws of quantum gravity. Solving the paradox would significantly deepen our understanding of the natural world.  From the symphony of galaxies to the mechanics of fundamental particles, unifying these two theories will answer all the questions and solve the mysteries of the Universe.  

Everything should be made as simple as possible, but not simpler. ~Albert Einstein

Relativity (Theory of the Big stuff)

 Our story began in 1905 when a patent clerk presented a radical view of the Universe.

The special theory of relativity

 The Special theory of relativity attempts to explain how speed affects space, time, and mass. It also says that mass is interchangeable with energy as defined by the infamous equation

𝐸 =𝑚𝑐2.

According to this equation, as an object approaches light speed, its mass becomes infinite, and the energy needed to move it increases, making it impossible for matter to exceed light speed.

An important aspect of Special relativity is Time Dilation. It can describe as “When an object is moving very fast, time slows down than when it is at rest.” The effect is not as apparent when the speeds are not extremely large. However, for a traveler moving at the speed of light, time should stop according to relativity.

Due to limitations, humans can’t travel near the speed of light, so this phenomenon is yet to be tested. However, this was experienced at a much smaller level when astronaut Scott Kelly spent nearly a year on the International Space Station while his twin brother, Mark Kelly, was on Earth. Mark was said to have aged a little faster than his brother due to time dilation; however, the difference was negligible. 

Einstein proposed that gravity is, in fact, the curvature of the space-time fabric.
Einstein proposed that gravity is, in fact, the curvature of the space-time fabric.

The general theory of relativity

In 1915, Einstein gave his General Theory of Relativity, expanding on topics like gravity and space-time. Einstein proposed that the Universe is made up of 4 dimensions and space and time are interwoven to form a space-time fabric continuum. According to him, time is relative. A person experiencing the same phenomenon from the North Pole will experience it at a different time than someone experiencing it around the Equator. 

Previously, gravity was thought to be a force (due to Newton’s theory), but Einstein proposed that gravity is, in fact, the curvature of the space-time fabric. Let’s take this example: Imagine a trampoline with a taut fabric. When you place a heavy object on it, there is a depression created in the fabric. If you place a ball on this trampoline, the ball will automatically roll toward the depression. 

Now let’s apply this example to a much larger scale. Planets have a mass, which creates a bump in the fabric of space-time, and so does the moon. As the moon revolves around the Earth, it gravitates towards the depression created by Earth in the fabric of space-time. This attraction is gravity. According to Einstein, gravity is not a force. Any object with mass will disturb the space-time field, causing other objects to gravitate toward it.

Another important aspect is Gravitational lensing. According to it, light bends around heavy objects. Astronomers observe this phenomenon as light bends around galaxies, black holes, and other heavy objects. 

Einstein’s theories became one of the most successful theories of all time. The General Theory of Relativity is renowned as one of the greatest scientific achievements of the 20th century. Its ingenuity, depth, and accuracy in predictions surpass all others. Einstein replaced Newton’s law of gravity, which stated gravity as “action-at-a-distance,” with a new idea of gravity as a bend in space-time. This laid the basis for contemporary understandings of the universe, including black holes and the Big Bang theory of the universe’s development.

Quantum Mechanics (Theory of the Small stuff)

Subsequently, in the 20th century, physicists like Planck, Bohr, and Einstein laid the groundwork for Quantum mechanics. It attempts to explain the nature and workings of the quantum world. The quantum theory’s biggest achievement is the Standard model.

The Standard Model gives us an understanding of the building blocks of nature. The particles are broken down into two: Fermions and Bosons. Fermions are matter particles and encompass all the matter present in this Universe. Fermions are broken down into Quarks and Leptons. Whereas the Bosons are the force carrier particles. They are responsible for the four fundamental forces: Strong force, Weak force, Electromagnetic force, and Gravitational force. 

The theory also provides a mathematical framework to predict the probabilities of various outcomes in quantum systems, such as particles’ position, momentum, and energy. The theory is known for its counterintuitive predictions, such as the superposition of states and entanglement. It is essential for understanding many phenomena in physics, chemistry, and technology.

The theory of quantum mechanics is a defining achievement in modern science and has proven to be one of the most successful theories in history. All experiments have agreed with its predictions, and despite numerous attempts, its validity has never been challenged. 

The current theory of quantum mechanics, known as the Standard Model of particle physics, has successfully explained the universe through four fundamental forces and demonstrated that three of these forces are different expressions of the same force. It has accurately predicted the existence of 17 particles, which were later discovered through particle accelerators.

Despite its triumphs, quantum mechanics also presents physicists with several counterintuitive truths, such as “spooky action at a distance.” This occurs when two particles become so interconnected that a measurement of one particle instantly affects the other particle’s state, regardless of their distance.

Clash of Titans

The Theory of Relativity deals with the laws of gravity and large-scale structures of the universe. At the same time, Quantum Mechanics explains the behavior of matter and energy at the atomic and subatomic levels. However, they are incompatible with each other in their predictions for the behavior of particles at these very small scales.

Nature

Relativity considers objects as indivisible masses in space-time, while Quantum Mechanics views matter as probability waves rather than localized particles. Relativity predicts definite outcomes, but Quantum Mechanics provides only probabilities. When applying Relativity to the scale described by Quantum Mechanics, the results are not meaningful.

Space time continuum

General Relativity describes space as continuous, while Quantum Mechanics views it as quantized or granular. Einstein’s 1915 theory of General Relativity explains gravity as a continuous force that shapes the geometry of spacetime. In contrast, quantum mechanics regards forces as discontinuous and made up of ‘quanta’. As a result, there is no equivalent concept of a gravitational field in conventional quantum mechanics, unlike the other three fundamental forces. 

The division between General Relativity and Quantum Mechanics can be considered “smooth” versus “chunky”. General Relativity is continuous and deterministic, meaning every cause has a specific local effect. On the other hand, quantum mechanics involves probabilistic, discontinuous events that occur in “quantum leaps” through the interaction of subatomic particles. Quantum mechanics permits connections not allowed by classical physics.

The black hole information paradox

General Relativity and Quantum Mechanics have conflicting views on black holes. General Relativity says that objects entering a black hole will be destroyed, erasing all information except spin, charge, and mass. On the other hand, Quantum Mechanics states that information cannot be destroyed. This creates the black hole information paradox. According to Hawking, the information about objects entering a black hole is lost. 

It cannot be predicted through Hawking radiation because the interior of the black hole is cut off from the external universe by the event horizon. The loss of information violates energy conservation and quantum mechanics, which requires micro-reversibility. The violation of micro-reversibility also destroys energy conservation. Thus, if the information is lost, quantum mechanics needs to be modified, and if it’s not, general relativity must be adjusted to allow the escape of information through Hawking radiation.

Solution

The Theory of Relativity and Quantum Mechanics are two pillars of modern physics, but they clash in their description of reality at the smallest scales. This is why physicists have been trying to develop a unified theory that can reconcile these two theories, known as quantum gravity, for many years.

Quantum Gravity is a theoretical framework that aims to reconcile the principles of quantum mechanics and general relativity to create a comprehensive description of the behavior of matter, energy, and gravity at all scales, from the smallest subatomic particles to the largest structures in the universe. 

It is considered one of the most challenging problems in theoretical physics because the principles of general relativity and quantum mechanics are so fundamentally different. Attempts to merge these two theories have been ongoing for many years, and various theories have been proposed, including string theory, loop quantum gravity, and non-commutative geometry. However, a complete and universally accepted theory of quantum gravity has yet to be established.

The development of a successful theory of quantum gravity has necessary implications for our understanding of the universe. It could answer questions such as what happened during the Big Bang, what happened in the first few moments of the universe, what happens inside black holes, and whether the universe has a quantum origin.

In the 20th century, several key discoveries about the universe were made, including Stephen Hawking’s work on black hole decay through radiation and Cosmic Microwave Background radiation. These findings showed that matter exhibits quantum behavior but moves following classical spacetime, leading to the development of semi-classical gravity, a bridge between quantum mechanics and general relativity.

Black holes located in the universe’s outer reaches could hold the key to unifying these theories, a belief held by Hawking himself in his “theory of everything.” The intense gravitational pull of black holes, which can even trap light, could reveal how macroscopic and nanoscopic particles interact.

Hawking’s work on string theory and Hawking radiation, a type of radiation emitted by black holes, brought him close to bridging the gap between quantum mechanics and general relativity. Despite being too small to observe, Hawking radiation provides insight into what a unified theory may look like.

Potential solutions to quantum gravity and various mathematical dualities have been debated for years. It remains uncertain if our fundamental understanding of physics needs to be revised. A unified theory of quantum astronomy could revolutionize our understanding of the universe and lead to a new era of theoretical physics and cosmology.

Key Takeaway

The quest for uncovering the mysteries of the universe is a journey that may take science many more years to complete. Despite numerous attempts, the intersection between relativity and quantum mechanics remains a mystery. Nevertheless, the journey toward uncovering the truth has begun.

Science isn’t just about finding answers but also about raising new questions. The most compelling theories are the ones that inspire further inquiry, leading to a never-ending cycle of discovery and exploration, much like the infinite nature of space-time.

Science and the Environment: An overview of discoveries and research

Environmental science is a discipline that integrates ecology with biology, chemistry, geology, and meteorology with a dash of physics and engineering to study our surroundings and the interaction of humans with these surroundings.

It cannot be called a purely biological field because only its subfield ecology is related to the study of the ecosystem and the delicate balance that is maintained to support this intricate reliance of life forms on each other.

The rest of the subfields, like geology and meteorology, focus on the physical and structural aspects of the earth and its environment, for example, the chemical and physical compositions of matter that makes up the environment and how these molecules interact and impact the surroundings,

Environmental sciences thus integrate chemistry in the sense of studying compositions and interactions, biology in the sense of studying life and its relationship with its environment, and physics because of studying the properties of matter that make up the environment into a new field of earth science.

History

Environmental sciences are not a new field; they go back many centuries. However, discoveries are still at their peak today because of the changing dynamics of the earth’s atmosphere, climate, resources, and wildlife due to human impact on these factors.

Dr. Rex N. Olinaires is considered the father of Environmental sciences. He was a professor at the University of the Philippines and his work was on water sanitation and its impact on the spread of microorganisms. He highlighted the fact that poor sanitation is the root cause of all environmental pollution.

The Industrial Revolution in the 1960s was basically a turning point for scientists studying nature to realize that human activities adversely impacted wildlife and the environment. This led to studying these impacts, the study of the environment and mechanisms to cope with environmental problems.

The realization of replacing traditional plastics with bioplastics is an example of one of the most groundbreaking research in environmental sciences.

Major Discoveries 

It is interesting to note that the field of environmental science deals with problems created by Man himself. Human beings exploited the natural resources of this planet to industrialize and manufacture goods for their own benefit. They exploited the resources to the point of damage to the natural ecology and environment of the planet. 

The next set of discoveries and research has basically been focused on solving these environmental problems and aiming for enhanced sustainability.

Earlier discoveries were more about using the environment for human industrial purposes, for example, the extraction and purification of natural power resources, processing of these resources to find useful products, and understanding the plants and animals of this planet and how they survive in their habitat. 

Their relationship with each other in the community and their habitat in their environment were the main research topics.

The realization that the environment can have a direct impact on humans’ quality of life came a bit late down the road;
The realization that the environment can have a direct impact on humans’ quality of life came a bit late down the road

Earlier environmental science research also focused on applying technology to understand the atmosphere, climate, structure, and composition of the earth and its water bodies and how everything worlds and is interconnected.

The realization that the environment can have a direct impact on humans’ quality of life came a bit late down the road; when resource exploitation crossed limits, the industrial revolution became unaware of its effects, and human health started deteriorating. 

Pollution, wildlife extinction, global warming and climate change then became hot topics for environmentalists, and research focused on eliminating these problems for sustainability.

Significant alternatives like renewable energy resources, a ban on hunting, fish farming, and other wildlife exploitation activities, waste management and recycling, microbiology, and biotechnology applications for tackling environmental challenges became the center for research.

The realization of replacing traditional plastics with bioplastics is an example of one of the most groundbreaking research in environmental sciences. Using natural polymers makes bioplastics environment-friendly and does not ‘build up’ in the food chain either. Scientists are further looking for similar innovative ideas. 

Every year universities and organizations collaborate to find solutions for environmental sustainability. One such example is the FICS competition by NUST in collaboration with PepsiCo. In this competition, students and their supervisors were required to submit proposals to find innovative and creative solutions to tackle plastic waste in the country in a sustainable way. The winner would receive funding for their project by Pepsi Co.

Let’s take two examples of titles of research articles from Nature Magazine from the year 2023 to get an idea of the kind of research under focus.

An interesting story focuses on the importance of honeybees as pollinators and contributors to the planet’s biodiversity. The effects that pesticides have on their epigenetics are causing their population to decline. 

Although this article highlights aspects of molecular biology by showing how chemicals in pesticides alter gene and protein expression, it is a good example of the effect of human activities on wildlife and, therefore, the environment.

According to another report published in Nature, the impacts of human activities and water pollution on the coral reef have been explicitly discussed as how the coral reef has adapted to its new environment. This interesting article focuses on the ability of nature to adapt to change and heal with time if given a chance.

Conclusion

The environment will continue to be a topic of interest to humans because of our dependence on it and its resources. To stay on this earth, we must deal with the environmental challenges we have created. The ultimate goal is sustainability and better quality of life for humans.

Is Atom Bomb for the greater good of mankind?

Is Atom Bomb for the greater good of mankind?

With the power to cause havoc and pronounced destruction, the atomic bomb was a contentious invention of mankind. The impact of a mere nuclear reaction took away the lives of many and demolished entire cities (Hiroshima and Nagasaki): the effects of which prevail to date. Possessing a nuclear weapon may signify the power to some; others may beg to differ. Behind closed doors, the study of the radioactivity phenomenon, the behavior of alpha particles, and the properties of materials when irradiated by the “Nuclear Group” formed the basis of the worse that was to come: Atomic Bombs.

“No one who saw it could forget it, a foul and awesome display” – Kenneth Bainbridge

Beginning of an era

A letter of warning from the Nobel Prize laureate Albert Einstein, in October 1939 to Franklin Roosevelt, the US president, hinted at the possibility of Nazi Germans developing a nuclear weapon. The US government launched “The Manhattan Project” on the severity of the issue in August 1942. Major General Leslie Groves led the operation and gathered Ingenious scientists and researchers from across educational institutions and research labs. Private corporations such as DuPont provided all the necessary assistance and components needed to make atom bombs. For safety purposes, the facility was located on the outskirts of the desert in New Mexico.

The intensity and determination to accomplish the project were evident by the fact that, at a point, there were approximately 130,000 Americans across thirty-seven facilities working for the success of the Manhattan project. The first nuclear bomb was tested at a military facility in New Mexico amid the early morning darkness. The impact was significant, and the explosion was bright. Though it might look like an apparent success, using these nuclear bombs was inevitable.

Once it became discernible that Japan would not surrender in the war, Harry S Truman, the president of the United States, ordered the use of nuclear bombs on Japan. Though he was warned by US armed forces that the destruction post-nuclear bomb was inevitable and catastrophic, Truman was determined to ensure Japan’s surrender.

6th August 1945 was a dark day in the history of Japan when an American B-29 bomber, “Enola Gay”, dropped the first atomic bomb on the Japanese city of Hiroshima.
6th August 1945 was a dark day in the history of Japan when an American B-29 bomber, “Enola Gay”, dropped the first atomic bomb on the Japanese city of Hiroshima.

The darkest day

6th August 1945 was a dark day in the history of Japan when an American B-29 bomber, “Enola Gay”, dropped the first atomic bomb on the Japanese city of Hiroshima. The explosion resulted in approximately 140,000 causalities, followed by radiation poisoning that persisted months later. Truman hoped that Japan would surrender after this attack, but Japan did otherwise. The reaction instigated Truman, and he called for another nuclear attack on Nagasaki (Japan), just three days after the first nuclear attack. The second round of bombing resulted in 210,000 people losing their lives with inexorable vandalization.

Wrecked Cities: Hiroshima and Nagasaki

Hiroshima and Nagasaki saw the most devastating aftermath of the nuclear attack, the effects of which still exist. Apart from the pernicious loss of lives, a large population developed medical conditions such as cancer and leukemia post-exposure to radiation. The bombing of Nagasaki caused the surface temperature to rise to 4000 degrees Celsius, followed by a downpouring of radioactive rain. It dismantled 70% of buildings, accompanied by a lack of immediate relief to mitigate the capacity of damage caused.

Several years post the 1945 disaster, the number of patients who developed chronic diseases, blood cancer, respiratory disorders, and DNA mutations increased. Perhaps the children were the greatest group of individuals affected by leukemia. Children became prone to developmental disorders, intellectual disabilities, and stunted growth.

Ramifications of Nuclear Power

When it comes to energy, perhaps one of the most heated debate topics is the provision of nuclear energy and its effects on mankind. Do the perils of Nuclear Energy outweigh its possible benefits? Let’s have a look!

The brighter side 

Nuclear power does not produce direct carbon dioxide in terms of energy production. Less carbon dioxide means less contribution to global warming. Moreover, nuclear power plants produce a significant amount of energy at a steady rate which is essential to keep up with the increasing energy demands. Furthermore, the entire setup and development of nuclear power generates jobs and have a higher mean average salary. In addition to this, nuclear power does provide the provision of national security for any country possessing nuclear weapons.

A matter of concern

However, constructing a nuclear power plant requires a lot of energy and manpower. Massive amount of radioactive waste is produced, a side effect of nuclear power plants. This radioactive waste can remain active and release radiation for several years. Workers working in the plant may be exposed to frequent radiation that imparts health problems such as chronic diseases and cancers. The thermal radiation post-nuclear explosion can cause significant skin burns. The shock waves produced as a result of a nuclear explosion can damage the ears and the lungs.

Raidan exposure

Although nuclear power operations are highly organized and tailored for safety protocols, natural disasters (earthquakes), human errors, leakage, and mechanical inconsistencies can cause contamination and release of radioactive matter.  For instance, a core meltdown, else known as the “beyond design basis,” causes a reactor to emit radiation (ionizing radiation) into the environment. Workers are at the greatest level of exposure to such radiation and may develop conditions such as acute radiation syndrome (ARS).

Waterbodies at risk!

Environmental impacts of nuclear power are inevitable. Usually, nuclear facilities are located near water bodies (lakes, rivers) as water is needed to cool the nuclear reactors. However, the cooling water, post usage, alters the conditions of the water bodies. Temperature changes in water can affect aquatic life adversely. Water that is too cold or too warm can potentially kill or harm these aquatic beings. It may affect their movement, food availability, feeding patterns, sleep cycle, and the underwater ecosystem.

Underground mining 

Moreover, nuclear facilities require uranium for their operation. Uranium is mined, and these mining activities can pollute nearby lakes and underground water, cause loss of habitat, and change soil composition (ph changes).  Furthermore, underground mining poses a significant threat to the lives of miners. Vast quantities of radon gas, a radioactive gas, are released during this process which is associated with lung cancer. Dust emitted can result in medical conditions such as pneumoconiosis.

Climate Change 

Nuclear plants are highly prone to climatic changes. Alterations in air and water temperature, wind speed, and precipitation rates hamper the efficiency of nuclear facilities and risk their safety. Floods and hurricanes can reduce the water supply to nuclear plants and damage them, causing a decrease in energy production, financial losses, and potential contamination of drinking water supplies.

Explosion Disasters

Post-nuclear explosion, the smoke and dust rise to a higher level of the atmosphere, causing a significant drop in land temperatures by blocking sunlight. Such temperature variations can result in a shorter growing season and potentially decrease overall agricultural production and fish stocks. It is an alarming situation as it can be followed by episodes of famine and food shortages.

As Albert Einstein said:

“The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one”

The Scientific advancements in Islamic golden age

The classic Golden Age of Islamic biography was an era of incredible scientific, social, cultural, philosophical, and economic buoyancy in the history of Islam, which traditionally dates from the 8th century to the 14th century CE. This Golden Era is thought to have begun during the reign of Abbasid caliph Haroon al-Rashid (786 – 809 CE) when he established the House of Wisdom in Baghdad- the biggest and the most prestigious Educational Capital of the world and the heart of remarkable Muslim scholarship which recruited renowned scholars from all over the globe including Muslims, Christians, and Jews.

They collaborated peacefully there to produce world-class intellectuals and polymaths in all the fields of knowledge-be religious studies, philosophy, biological sciences, chemistry, mathematics, physics, earth sciences, astronomy, industry, technology, law, literature, art, architecture, politics, economy, or sociology. This Islamic Empire of knowledge brought many cultures together under one umbrella beyond their races, colors, demographic distribution, or religion, which is the true essence of Islam. 

Scientific Advances in Islamic Golden Age

Biology and Medicine

Bu Ali Sina (Latinized as Avicenna), is known as the father of Medicine. His contributions to biology and medical sciences have set up the profound basis of modern medicine, and his book The Canon of Medicine is still part of the operational curriculum of medical sciences in the west. He also discovered the causes of contagious diseases and introduced the concept of quarantine to limit the spread of contagious diseases; he laid the foundations of sub-fields of medicine such as experimental medicine and evidence-based medicine, trial methodologies like clinical trials, control trials, and efficacy testing. 

Bu Ali Sina also introduced clinical pharmacology and separated it from medicine. His other significant contributions include the explanation of microorganisms like bacteria and viruses, research-based studies on the contagiousness of tuberculosis, water and soil-borne diseases, skin diseases (STDs), sexually transmitted diseases, perversions, and the ailments of the nervous system. 

Other Muslim physicians of the golden age also have made miraculous contributions in the fields of physiology, ophthalmology, pharmacology, surgery, anatomy, pathology and medicine. With their inventive approaches, they were the pioneers in opening up hospitals, including medical schools and psychiatric clinics, the invention of surgical instruments and procedures, including dissections and postmortem autopsies, and comprehensively elaborated diagrams of human anatomy and physiology.

The notable among the best physicians and researchers of the golden age who led the edge in the field of medicine and biology are Al-Kindi, Al-Razi (Latinized as Rhazes), Abu al-Qasim (Abulcasis), Ibn Zuhr (Avenzoar), Ibn al-Nafis, Ibn al-Lubudi, Ibn Khatima, Ibn al-Khatib, Mansur Ibn Ilyas and Al Zahrawi.

Chemistry

Jabir bin Hayyan (Latinized as Geber) is known as the Father of Chemistry, who pioneered the use of the scientific method in the field of chemical sciences. He also introduced the Lusterware, alembic, retort, still, and chemical processes of filtration, distillation, crystallization, liquefaction, purification, sublimation, oxidization, and evaporation. He also has another feather in his cap of preparing sulphuric acid and nitric acid, the strongest known acids, and laid the foundation of acid-base in chemistry.

Another influential Muslim chemist of this era was Al Razi, whose contributions shook the basis of Aristotle’s and Galen’s chemistry. Invention of kerosene oil and kerosene lamps, soaps, distilled petroleum, and antiseptics experimentally proved the qualities of matter like oiliness, inflammability, sulfurousness, and salinity.

For the first time in the history of chemistry the Muslim alchemists separated the concept of organic and inorganic chemistry, they made major contributions in metallurgy and the use of acids and making salts. A huge number of laboratory apparatus was made during this golden era, and metallurgy was introduced extensively. 

Some of the very basic laws of physics have been put forward by Muslim physicists of the Golden Age.

Physics

Some of the very basic laws of physics have been put forward by Muslim physicists of the Golden Age, like the law of inertia, momentum, the law of gravitation, and even the precursors to Newton’s laws of motion were also conceptualized by Muslims.

One of the groundbreaking inventions of the Golden Ages of Islam was the pinhole camera invented by a renowned Muslim optician Ibn Al Haitham, a polymath, in the 11th century who is also considered a pioneer of modern optics, experimental Physics and regarded as The Father of Optics due to his exceptional achievements. Ibn al Haitham also developed the methodology of the scientific method to answer scientific queries systematically.

Many inventions have been produced by Muslim engineers and inventors, like the very first flying machine was constructed by Abbas Ibn Al Firnas.

Renowned Muslim physicists of this era are Ibn al-Haytham, Bu Ali Sina, Hibat Allah Abu al-Barakat al-Baghdadi, Ibn Bajjah (Latinized Avempace), Jafar Muhammad Ibn Musa, Ibn Shakir, and al-Khazini.

Astronomy

The successors and predecessors of the Maragha School of Baghdad were thought to be the pioneers of many astronomical discoveries and inventions, including the construction of the first observatory, the evidence of Earth’s rotation on its axis, the collection of astronomical data and correction of the previous astronomical concepts, resolving considerable problems in the Ptolemaic Model, development of astrolabes, invention of numerous astronomical equipment and laying the foundations of celestial mechanics and astrophysics.

 The eminent astronomy scholars of this era are Ibn Al-Shatir, Nasir Al-Din Al-Tusi, Ali Qushji, Al-Birjandi, Ibn Al-Haytham, and Mo’ayyeduddin Urdi.

Geography

The drawings and illustrations of the world map by Muslim cartographers and geographers of the golden age were so mind-blowing and accurate that they are still in use today with nominal amendments.

The famous three-meter world map designed by Al-Idrisi, an Andalusian cartographer, is regarded as the complete and calculated world description. This map was part and parcel of the travelers as it contained quite detailed descriptions of the whole Islamic world as well as Africa, the Far East and the Christian north. 

Mathematics

The field of mathematical sciences owes a tremendous debt to the Islamic Golden Era. The historical achievements of Golden age Muslim mathematicians are the developments of algebra and algorithms by Muhammad Ibn Musa al Khwarizmi, spherical trigonometry, the use of decimal point notation in numerals by Sind Ibn Ali, the introduction of crypt-analysis and frequency analysis by Al Kindi. 

The introduction of algebraic and integral calculus, proof by mathematical induction, analytical geometry, and formula for infinitesimal by Ibn Al-Haytham, the first confutations of Euclidean geometry and the parallel postulate by Nasir al-Din al-Tusi, algebraic geometry by Omar Khayyam, the concept of non-Euclidean geometry by Sadr al-Din, the development of symbolism in algebra by Abu al-Hassan Ibn Ali al-Qalasadi, and numerous other advances in algebra, arithmetic, calculus, cryptography, geometry, number theory, and trigonometry was the marvelous accomplishments of Golden Age Muslim mathematicians. 

Many machines were invented during this era of renovation and many basic automatics were first introduced by the great Muslim inventors.
Many machines were invented during this era of renovation and many basic automatics were first introduced by the great Muslim inventors.

Technology

Many machines were invented during this era of renovation and many basic automatics were first introduced by the great Muslim inventors. Among these machines, the revolutionary crank-connecting rod system was installed in machines that converted the rotary motion to linear motion, thus raising heavy objects with much ease. This cutting-edge technology, discovered by Al-Jazari in the 12th century CE, expanded globally and became essential to everything big and small, from the bicycle to the internal combustion engine.

Agronomy & Agriculture

Arab Agricultural Revolution is a notable advancement in the field of agricultural sciences during this era. Many novel techniques of plantation and innovative methodologies were invented to yield the increased production of crop plants.

Muslim engineers introduced fossil fuels, hydropower, tidal power, and wind power to run the power mills and factories.

The development of the scientific approach to agriculture was determined by Muslim Agriculturalists and their approach was majorly based on three elements; crop rotation system, systematic irrigation techniques, and introducing the diversity of crops, which were priory cataloged according to the land type, water requirement and possible seasonal effects.

Exotic crop varieties from around the world, such as sorghum from Africa, citrus fruits from China, rice, cotton, and sugar cane from India, were introduced to the Arab soil, which generally had never experienced the growth of such plants. The experimented farming successfully imparted a sudden boost to the economy, urban growth, vegetation cover, and employment opportunities, ultimately raising the quality standards of Arab life.

Industrial Revolution

Muslim engineers introduced fossil fuels, hydropower, tidal power, and wind power to run the power mills and factories. A wide variety of mills was employed by the Muslim industrialists, including steel mills, sawmills, hullers, grist mills, stamp mills, windmills, ship mills, sugar mills, and tidal mills. By the start of the 11th century, the huge variety of mills started operating throughout the Islamic World, from Al- Andalusia, Spain, and North Africa to Central Asia and the Middle East.

Other than these, distillation technologies, the discovery of acids, pharmaceuticals, perfumery, the silk industry, textiles, weaponry, the mining of minerals, the invention of astronomical instruments, and the use of ceramics are amazing additions by Muslims. The invention of crankshafts, water turbines, the installation of gears in mills, and the concept of dams and water reservoirs to store water were also notable inventions among countless others by Muslim Engineers of this era.

These novel mechanized advancements made it possible to carry out many industrial tasks efficiently in less time, reducing manual input, which ultimately pedaled up the revolution in the industry. This whole wave of revolution was transferred very rapidly from the center of the Muslim world to Europe, Asia and Africa.

 Conclusion

The struggle for learning and excellence in learning are the fundamentals of Islamic values. Our forefathers were the great harbingers of knowledge and research who led the world in all the fields of knowledge. The sky was the limit for them that’s why they are still shining.  They have a profound impact on today’s education and learning. The whole western world has recognized that the scholars of the Islamic golden age were the best successors and predecessors of intellectualism the world has ever witnessed. We must follow in their footsteps to bring back the glory that once belonged to Muslims.

Astronomy Breakthroughs in 2022

Astronomy, the new and the old perspectives, has always been the source of unbelievable news and unusual mysteries. It leaves its followers in awe and amazement with its each novel discovery. The race to find bewildering enigmas of space capacities is constantly in progress. It won’t be wrong if we document the year 2022, as the year of amazing spatial discoveries.

ENCHANTING SPACE IMAGERY

Telescopes used to visualize the atmosphere beyond the boundaries of Earth; see it thoroughly and depict the undistorted imagery of space. The notable amongst them is Hubble Space Telescope.

JWST (James Webb Space Telescope)

The James Webb Space Telescope is the largest and the most powerful telescope which uses complex mechanics to see the panorama of the universe, unveils the spell bounding cosmic mysteries, and manifests the clarion of space imagery.

The distinctive gold-plated JWST has been introduced by Joe Biden, the President of the USA, whose phenomenal development is the joint effort of Canadian and European space agencies in collaboration with NASA. This accounts to be one of the most expensive and complex missions ever introduced in space with a worth of $10 billion. It was neither an easy construction nor so elementary to be installed. Its manufacturing took approximately 20 years, facing multiple setbacks in its operational journey.

The first images and information that beamed back to Earth by JWST proved that the lifelong efforts didn’t go in vain. The astronomers were awestruck by the mindboggling imagery and data received. Those images are just the notions of what is following next.

It is speculated that JWST might renounce all other space telescopes and will prove to be the most authentic source of cosmic data which will fuel thousands of research papers worldwide. In no time and without any doubts it will revolutionize the whole present picture of universe in coming years.

RECENT BREAKTHROUGHS

  1. The Glimpse of the Most Distant and The Ancient Galaxies

Galaxies, the gigantic assortment of heavenly masses spread across the sky. They have billions of stars, planetary systems, asteroids, comets, meteorites and massive clouds of dust and gases. Our Milky Way galaxy is an enormous array of celestial bodies.

A team of astronomers has reported the recent discovery of some of the earliest galaxies visualized by NASA’s James Webb Space Telescope which are thought to be created 400 million years after the Big Bang. The data collected earlier unveiled some of the records of such faint galaxies but now, with the JWST’s spectroscopic observations, their fingerprints have been confirmed.

11th of July, 2022 is documented as the day of remarkable discovery in the history of space studies. It was a live broadcast from White House when President United States, Joe Biden witnessed the commixture of thousands of galaxies by himself and was overwhelmed at the glimpses.

JWST has provided the pictorial data of the most distant celestial collections in the midst of December 2022. Almost four distant galaxies have been observed by JWST one amongst them is the far off reddish galaxy expected to be 13.8 billion years old-the most ancient one. Researchers speculated that the newly discovered galaxies are extremely beyond the distances they have anticipated before the JWST’s observed data.

  1. Discovery of Exoplanets

Exoplanets, beyond the borders of our solar system, dwell massive number of colossal planets. They orbit stars other than sun. They might be Gas Giants, Neptunian, Super Earth or terrestrial. 

The first exoplanets were discovered in 1990s and today there are over 3000 known planetary bodies orbiting around the stars. Among them only a few have been pictured directly. Most of the exoplanets are so far-flung to be detected easily. But thanks to JWST, in September 2022, the direct image of an exoplanet was captured. Moreover, NASA confirmed the presence of over 5000 exoplanets including super-Earths, gas giants and dwarf planets beyond our solar system. This great discovery has rippled the overall momentum of space studies and astronomy.

Images taken by JWST in early November 2022, researchers spotted some exciting floating entities on, probably, the northern hemisphere of Saturn’s alien moon named Titan.

Titan captivates scientists and researchers of astronomy for multiple reasons. Firstly, the intense ultraviolet radiations coming from the sun create a huge buildup of organic molecules in Titan’s nitrogenous and methane-rich atmosphere. This dense and hazy atmosphere obscures its surface drowned in expanded stretches of dunes, along with lakes, rivers and seas of liquid hydrocarbons like ethane and methane. Secondly, the scientists suspect that deep underneath the Titan’s surface, there might be the reservoirs of a salty liquid water ocean, making Titan a habitable for extraterrestrial life.

Clouds on Titan might be a dime a dozen to any casual observer. But to the astronomers, clouds revealed a lot about the atmosphere of Titan. As Titan is the only moon in our solar system to have a dense atmosphere of nitrogen and methane that is stretched about 370 miles (600 kilometers) into the space, 10 times taller than the altitude of Earth’s atmosphere, according to NASA. So, clouds will help a lot to study about not only the atmosphere of Titan but also why Titan has atmosphere which other moons, in the solar system, are devoid of.

These clouds also validate the weather patterns which predict the appearance of clouds in the northern hemisphere of Titan during its summer season, the time when that region is entirely bathed in sunlight.

The year 2022 was the year of ground-breaking explorations and cosmic revelations. It will surely open the massive avenues to the new realms of astonishing astronomical discoveries. It was a just the beginning with the wonder-scope JWST. More is yet to come.

Problems involving interstellar communication

Are there intelligent beings elsewhere in our Galaxy? If not, where are all the Aliens? This question gives rise to one of the most profound paradoxes in history, known as The Fermi Paradox.

Named after the Italian-American physicist Enrico Fermi, this paradox is one of the biggest unsettled questions in astrobiology. The idea started when, in 1950, Fermi asked his co-workers over lunch where are the extraterrestrials. If there are billions and billions of stars and probably even more planets, indeed, we are not the only intelligent beings in the universe. Then why have we not already been in contact with the outers?

People have debated this for many years. Various articles and books have been published arguing if aliens do really exist, we should have been aware of them already. If we have not found any trace of life outside Earth yet, then they possibly do not exist. Let us look deeply into these claims and explore some solutions scientists have put forth over the years.

Possibility of life outside Earth

The expectation that the universe should be teeming with intelligent life is linked to models like the Drake equation. It suggests that even if the probability of intelligent life at a given site is small, the sheer multitude of possible sites should yield many potentially observable civilizations.

It is not the size of the universe that is important per se, but the fact that it is big enough to contain a vast number of habitable planets. We do not know precisely how many such planets are out there, but one recent estimate suggests that our galaxy might contain as many as 100 billion Earth-like planets.

The Fermi argument extends in a way by saying that it is highly likely that some of these planets will have intelligent life forms that might have developed advanced technology. But then again, we have no sign of extraterrestrial communication whatsoever.

Scientists have tackled the paradox through different scenarios based on logical reasoning. Following are a few arguments in some theories that are documented.

Problems with interstellar communication

Communication is not as accessible, as one would think!

SETI (Search for Extraterrestrial Intelligence) is a non-profit research organization that monitors electromagnetic radiation for signs of communication from other planets. Although it has been trying to listen for the last 6 decades, all efforts went in vain. Part of the failure lies in the fact that we have only sampled a small portion of the universe.

Let us understand this with an analogy: if you went to the beach with a glass and scooped up some water, would you expect to find fish in it? Probably not; that does not mean there are no fish in the ocean. It just means we have not collected enough water to find those fish. The same is true with SETI; they have not checked out enough of the universe to conclude if there is someone out there.

“If we ever hope to pick up the signal from out there, we need to build a radio telescope the size of the metropolitan area of Chicago, which is twenty-five thousand eight hundred square kilometres. Then, it would be possible to detect a radio signal hundreds of light-years away. The only problem is such a telescope in our economy would cost more than 60 trillion dollars,” says Keith Cooper, a famous science journalist, in his book ‘The Contact Paradox’.

Moreover, communication is only achievable when we assume that out there civilization is as advanced as ours is. However, the Copernican Principle that asserts that we are not unique in any way suggests that the odds are far too slim that another planet is at precisely the same point in its development. The calculations hint that the signal would have to traverse a distance of more than ten million light years for more than two millennia before we receive a response. Hence, we will not get a response, even at light speed, before the year 4000 C.E.

This implies that the universe is incredibly vast. It would take centuries to establish the first contact, as far as the math is concerned.

Rare Earth hypothesis

The Rare Earth Hypothesis deals with the notion that planets like Earth are scarce. Life and the evolution of complexity require a combination of astrophysical and geological conditions that are uncommon in our Universe. In other words, we are pretty special and unique. Thus, a complex ET life is an improbable phenomenon which is likely to be rare throughout the universe.

In 2000, Peter D. Ward and Donald published a book titled “Rare Earth: Why Complex Uncommon in the Universe”. In their book, the authors indicated eighteen factors that allow complex life to evolve until they obtain intelligence. Most of them are very unlikely, and their relative independence implies that their probabilities must factorize, making the resulting probability for intelligence to evolve elsewhere than Earth very low.

Dark forest theory

This possible answer to the Fermi paradox says that the aliens out there are silent simply because they do not wish to be on the receiving end of possible destruction by another civilization. Just like hunters moving cautiously through a dark forest, they all must remain quiet; otherwise, they will be found and killed.

This would also explain why we have not found any mundane alien radio signals despite a century of being able to pick them up. Just as we accidentally send our radio signals, meant for us, out into space, another civilization would be likely to as well. One possibility is that other civilizations are so frightened of being detected that they deliberately avoid sending such evidence into space.

Nonetheless, the possibility of an alien civilization that has a similar risk aversion level and reasoning process as we do must be taken into account.

Indifferent theory

With billions of years of history at play, it might not be the case where we are at technological parity with all the other forms of life that might be out there. Alien life might simply be so far beyond us that they could regard us as insignificant as we do when we think of an ant. Why do you not try to talk to the insects in your garden? The gap is too significant. They might not talk to us because they think we have nothing interesting to say. You understand what they want ideally, and they have no hope of understanding you, so the communication is, frankly, pointless.

Conclusion

When I infer in the light of these arguments is finding a substantial probability that we are alone in our galaxy or even in our observable universe.

Where are they? — Probably exceptionally far away, and quite possibly beyond the cosmological horizon and forever unreachable. But as of now, we are simply not listening to them correctly. Perhaps, in the near future, if we follow a more practical approach, which can provide certainty about intelligent life somewhere other than Earth. However, to be honest, for now, it looks more as if the aliens are just inanimate characters in science fiction movies.

Geology and the search for extraterrestrial intelligence

Are we alone in this universe, or intelligent beings like us do exist somewhere out there? Are there more advanced civilizations than ours, and have they developed a network of linked societies throughout our galaxy? These are a few questions that blow the mind of every curious individual among us.

Several theories have been presented about the origin of life on Earth. Many of them support the idea that it is possible to have many Earth-like planets or exoplanets beyond our solar system. These planets could have similar evolution processes that we witness on Earth. Scientists argue that such processes could be fairly common in the universe, and intelligent beings like us must exist on these planets.

Our evidence of the origin of life on Earth comes from the geological record of the planet. The record that geologists have gathered so far is collected from thin rocks nearly 2.7 to 3.5 billion years old. It confirms the presence of small inclusions, a 100th of a millimetre in diameter.

These evolved organisms, like bacteria and blue-green algae, must be the beneficiaries of a pro-long evolutionary process. Geologists didn’t find a rock on Earth that is more than 4 billion years old. Scientists believe that before this time, the planet’s surface had melted in the final stage of its creation.

Since life originated on Earth seems to be short than its present age, there is additional evidence that life may evolve on other planets in our solar system or beyond it, at least on the planets having an abundance of hydrogen-rich gases, liquid water, and a constant source of energy from their host star.


James Webb Space Telescope released its first image in July 2022, and the world is overwhelmed by break-taking deep space images revealed later. Since then, several significant questions have been around in space communities about the existence of life on exoplanets beyond our solar system. Digging deep into these most concerned questions of all time, Scientia Pakistan brings its exclusive edition on “Extraterrestrial life”.

We have got exciting stories on Sentient in the cosmos, microbial life, Fermi Paradox, NASA’s program on UFOs, use of modern technologies for the search for ET life, and much more. We exclusively interviewed Dr Munazza K Alam for this edition. Have an excellent read!
