"A Journey Through the Evolution of the Universe and Life on Earth"


The Big bang

The History of the universe is a long and complex one, spanning over billions of years. However, one of the most significant events that kickstarted this cosmic journey was the Big Bang, which occurred around 13.77 billion Earth years ago. To put this into perspective, if we consider the Big Bang to have happened at midnight on January 1, then we are now at midnight on December 31 of the Same year.

During the first few months after the Big Bang, the universe was a chaotic and rapidly expanding place. Elementary particles were forming and colling, and the first galaxies were starting to take shape. By March, the Milky Way Galaxy, which includes our own solar system, had formed.

In August, our sun and the other planets in our solar system began to form. And by September, the first known life had appeared in the form of unicellular organisms. This marked the beginning of the long and complex process of evolution that has led to the diversity of life on Earth today.

Over the next few months, several other key events occurred. In October. the Earth's atmosphere was formed through the process of oxidation. And in November, the first complex cellular life evolved.

However, it wasn't until December that the majority of the Significant events in the evolution of life on Earth took place. On December14, the first known animal on land appeared. This was followed by the evolution of the first fish on December17, the first plant on December 20, and the first insect on December21.

On December 22, amphibians evolved, and on December 23, reptiles appeared. On December 25, Dinosaurs came into existence, only to become Extinct on December 30, on December 26, mammals appeared, and on December27, birds evolved. Finally on December 28, flowers bloomed on Earth, marking the end of a significant chapter in the evolution of life.

This evolution took place within 4 hours in Cosmic Calendar

  

However, the most significant day in this cosmic calendar is December 31, the day when human life began to evolve on Earth. At around 6:12 am on December 31, the first apes appeared, and at 9:11pm, humans and chimps diverged. By 11:52 pm modern humans had evolved, marking the beginning of the long and complex history of our species.

From this point until  the stroke of midnight on December 31, we have seen the rise and fall of several civilizations, including the Indus Valley civilization, the Egyptian civilization, and many others. All of these civilization existed within the last 8 minutes of the cosmic Year, between 11:52 pm and 11:59:50pm.

The history of the universe is a fascinating and awe-inspiring tale of evolution, transformation, and constant change. And while we may only be a tiny blip on this cosmic timeline, our presence and our impact on the world around us are undeniable. As we look to the future, it is essential that we continue to explore and understand our place in the universe and work to protect and preserve the delicate balance of life that exists on our planet 

The main aim of my blog, is to organize various physics concepts in a cohesive manner so that readers don't have to refer to multiple sources for knowledge. All the content in my blog is written after referring to a few reliable textbooks.

Welcome to our blog, where we explore the fascinating evolution of our universe since the Big Bang. In our previous two blog posts, we discussed the stages of the universe's evolution in " Formation of our Wonderful universe ", and provided a timeline of the major cosmological events that have taken place since the Big Bang in " Cosmic Calendar ". However, for further understanding of the universe's evolution, we must first delve into the elementary and fundamental particles that existed before the universe's formation. This blog will serve as an introduction to these particles and their role in the universe's evolution. By understanding the basic building blocks of the universe, we can better comprehend how the universe has evolved into the complex and awe-inspiring entity we see today.

What do you mean by spin of the electron ?

 During school days all of us have learned that there is a quantum number associated to spin of the electron (spin quantum number s) which can take only two values +1/2 or -1/2, but what does this number tell us about the electron, ever wondered what is the significance of this spin quantum number in physics (or chemistry) is it related to the spinning of the Earth around it's own axis, lets go into the historical development of the concept of spin and try to understand what exactly spin means  In Mechanics we define spin as the rotation of a body along its own axis is that significance same for the small particles like electron? before going into much details lets understand a experiment which gave rise to this concept The Stren-Gerlach Experiment The Stern-Gerlach Experiment :  Stern-Gerlach Experiment   experiment was performed by Otto Stern and Walther Gerlach in Frankfurt, Germany in 1922 this is the era when the quantum mechanics was introduced to the wor...

Have you ever wondered over how the widely accepted Big Bang theory gained its prominence in the scientific community? The answer lies in a remarkable discovery that provided crucial evidence supporting this groundbreaking theory. In our latest blog post, we /explored the Cosmic Microwave Background (CMB). In this blog let's delve deeper into the Cosmic Microwave Background and understand its connection to the Big Bang Theory. Before Exploring the Cosmic Microwave Background let's explore few backgrounds which led Scientists to think something like CMB  The Space Time :  Before Einstein the scientific community believed that the Time is absolute and they were also sure that the Space and Time were independent of each other here space refers to the three co-ordinates that we use for defining position. Einstein suggested that the space and time are no 2 different independent term, but how one can relate time and spacial co-ordinates together? Let's explore how it is ev...
