Friends, you will be happy to know that I am writing a book on Cosmology. In this book, we’ll take a journey through the fascinating world of cosmology and explore the big questions that have puzzled scientists for generations. We’ll delve into the mysteries of the Big Bang and the ongoing expansion of the universe, explore the strange phenomena of dark matter and dark energy, and investigate the birth and death of stars and galaxies. We’ll also examine the search for extra-terrestrial life and the future of cosmology as a field of study.
But what is cosmology, exactly?
It’s true that the term may sound intimidating at first glance. But don’t worry – you don’t need a degree in physics or astronomy to understand the basic concepts of cosmology. At its core, cosmology is simply the study of the universe as a whole, including its origins, evolution, and structure.
So don’t be intimidated by the term cosmology – it’s simply a way of understanding the universe as a whole. As you read through the chapters of this book, you’ll find that the concepts and ideas become clearer and more accessible. So sit back, relax, and get ready to explore the awe-inspiring mysteries of the cosmos.
Beauty of Cosmos:
Have you ever looked up at the night sky and wondered about the mysteries of the universe? Do you find yourself curious about the origins of the cosmos and the forces that shape our world? If so, you’re not alone – these are questions that have captivated scientists and thinkers for centuries.
The beauty of the cosmos lies in its vastness, complexity, and elegance. From the smallest particles to the largest structures, the universe is filled with wonders that capture our imagination and spark our curiosity.
One of the most beautiful aspects of the cosmos is its sheer size and scope. The universe is home to billions of galaxies, each containing billions of stars, planets, and other celestial objects. The scale of the cosmos is truly mind-boggling, and it reminds us of just how small we are in the grand scheme of things.
Another beautiful aspect of the cosmos is the elegance and simplicity of its underlying laws and principles. From the laws of gravity and thermodynamics to the principles of relativity and quantum mechanics, the universe operates according to a set of rules that are both beautiful and profound. These laws and principles reveal a deep interconnectedness between all things in the cosmos, and they remind us of the wonder and mystery of existence itself.
Universal connectedness refers to the idea that all things in the universe are connected in some way, and that there is a deep underlying unity to all of existence. This concept has been explored in various spiritual, philosophical, and scientific traditions throughout history.
At its core, the idea of Universal connectedness suggests that everything in the universe is interdependent and interconnected. This means that every action, thought, and event has a ripple effect that can be felt throughout the cosmos. It also means that all living beings, as well as non-living entities such as stars and planets, are part of a larger web of life and energy.
In some spiritual and philosophical traditions, universal connectedness is seen as a fundamental aspect of the universe that transcends time and space. For example, in Eastern religions such as Buddhism and Hinduism, the concept of interdependent origination suggests that everything in the universe arises in dependence on other things, and that all phenomena are ultimately interconnected.
Scientific view of Universal connectedness:
In scientific terms, the concept of universal connectedness is often explored through fields such as quantum physics, which suggests that particles can be connected in ways that transcend classical physics. For example, the phenomenon of entanglement suggests that particles can become linked in such a way that the state of one particle can affect the state of another, regardless of the distance between them.
Our first chapter will be on ‘The Origin of our Universe”.
Origin of our Universe:
The origin of our Universe has been a subject of fascination for human beings for centuries. While many different cultures and religions have their own creation stories, modern cosmology provides us with scientific theories and concepts that aim to explain how the universe began. In this blog, we will explore six of the most prominent theories and concepts that attempt to shed light on the origin of the Universe. From the Big Bang to the multiverse theory, each idea offers a unique perspective on the nature of our Universe and how it came into being. Let’s delve into the mysteries of cosmology and explore the fascinating possibilities of our universe’s creation.
Six major theories and concepts that try to explain the origin of the Universe. The list is as below:
The Big Bang Theory
The Steady State Theory
The Inflationary Theory
The Ekpyrotic Theory
The Cyclic Model
The String Theory (M-Theory)
Two more theories are spoken of: One is Simulation theory and the other one is Holographic Theory.
The simulation theory:
The simulation theory of the universe suggests that our reality is actually a computer simulation created by an advanced civilization. According to this theory, everything we experience in the world around us, including our own thoughts and consciousness, is just a product of this simulated reality. While this theory has gained some attention in philosophy and theoretical physics, there is currently no scientific evidence to support it.
The holographic theory:
The holographic theory, on the other hand, proposes that the information about a three-dimensional object can be completely stored in a two-dimensional surface surrounding it. This suggests that the entire universe could be seen as a hologram, with the information about everything in the universe encoded on its two-dimensional surface. This theory has profound implications for our understanding of space, time, and the nature of reality itself, and is an active area of research in both physics and cosmology. The holographic theory is also closely related to the study of black holes, which are thought to be some of the most extreme manifestations of this principle.
The Big Bang Theory: –
The Big Bang Theory is the most widely accepted scientific theory explaining the origin of the universe. Because the Universe is expanding today, all matter is assumed to have been condensed and contained in only one point at the start. According to this theory, the universe started as a Singularity – a point of infinite density and temperature – around 13.8 billion years ago.
This singularity contained all the matter and energy that would eventually form everything we see in the universe today. This is called a Singularity and it lasted for a “Planck Epoch”. Planck Epoch is the time from 0 to 10-43 second. It is known as Planck Time.

Dear Arun Singha, a wonderful post. i have always wondered about the collapse of the dust cloud that our solar system formed in. Depicted always like a flat record in spacetime. But the disk collapsed at 60 degrees and goes forwards at the plane of the Solar ecliptic. In a sense, one could look backwards from where we are going (around Sirius) to perhaps find residue of our creator, the event that caused the dust cloud to begin the journey of life. please forgive my enthusiasm. Peace love and greetings from oz.
Very true. All your words are very lively and have a great meaning. I am a learner and trying to understand cosmology.
Your statements added insights on my post. I am encouraged.
Thanks a lot.
Beautiful write up sir..
Thank you Sir for your kind words.
It is very interesting and informative. I get to know a lot about universe. 😊👍
Thank you Preet for your beautiful words. Best wishes.
Excellent information shared!
Thank you so much for your comments. Best wishes.
I think, Arun, that the idea of the book is a very good one!
You write with clarity and precision.
Thank you so much Joanna. Your comments are always encouraging. These words give me extra power. I will publish next part very soon. Working on it.
Sir, I am always intrigued with mysteries of the universe we are embedded in. It’s mind-blowing to think about the interconnections between micro and macro universe. From the smallest subatomic particles to the vast expanse of galaxies, everything seems to be intricately connected in the grand tapestry of the universe. The more we explore, the more we realize how mysterious and awe-inspiring our cosmos truly is. It’s a humbling reminder of our place in the cosmos and how much there is left to discover. Your interest to bring cosmology into print will be beneficial to metaphysics enthusiast like me. Eagerly waiting for the other parts on this subject. Be safe and take care.
Sir, The above post is drafted from my laptop and wonder why it posted under anonymous instead! Anyways just wanted to clear the confusion.
Previously also I received like that. Initially I did not understand who Someone is. But from the style of comments, I understood it was you, Vishnupriya. Thank you so much for your comments.
Have a blissful time ahead.
Thank you so much Vishnupriya for high value inputs to it. From your comments, I get points for elaboration, for analysis and for deeper thoughts. Truely said that there is connection between micro and macro. It is mapping of point to point. In String theory, we will not see even micro. It is mere vibration only all around. Where is matter then? Matter is nowhere. So, what we see is Reality or not?
Thank you so much for your support and encouragement.
There is lot to do.
Need your support and best wishes. I get power from all of you in this window.
Matter is neither created or destroyed but purely remains for worldly transactional purposes. Just as electricity though invisible makes all electrical gadgets functional. I would like to share that lord Krishna divides the whole universe into 3 components here :
Ksarah Purusah / Manifest matter – Visible universe , perceptable to our sense organs
Aksara Purusah / Unmanifest matter – Invisible intangible universe, Maya tatvam
Uttama Purusah / Consciousness principle – Independent entity
Of the above three, first two are acetana tatvam, inert principle and the third one is sentient principle, cetana tatvam.
Uttama Purusah lends existence to the ksarah and aksarah purusah drama that is creation, sustenance and destruction.
Matter manifests, matter goes to unmanifest form.
All these drama is sustained by the Screen called Uttama Purusah.
Hence, Krishna says the third component is the Supreme One.because it is Sarva Aadharam.
Having said this much, Krishna says that Uttama Purusah, the Consciousness alone is My real nature.
The real God is formless Consciousness, all pervading.
All the forms attributed to God in religious scriptures are temporarily
Uttama Purusah of the 15th Chapter is the Para prakrti of 7th chapter.
Bhagavad Gita Talks
Thank you so much for sharing this highest knowledge from the Gita 15th chapter.
Once again I am recalling Knowledge imparted by Lord Krishna 🙏
Uttam Purusha is Nirguna Brahman. And Akshara Purusha is Iswara, as described in VEDANTA.
Now comes manifested Universe. That is ksara Purusha.
Am I right Vishnupriya?
I am very happy to see your analysis on the subject from The Gita.
Take care 😊🙏
