The ABCD of Physics that everyone should know

"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. Each Bright spots in this image is a galaxy on it self 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. Th...

 A Brief History of the formation of universe  In this blog we will discuss the evolution of universe from the big bang theory   The Big bang In 1916, German Theoretical Physicist Albert Einstein put forth his theory of general relativity, which revolutionized our understanding of gravity. Einstein's theory also predicted that the universe was expanding. In 1929, American Astrophysicist Edwin Hubble observed the hydrogen spectra of distant galaxies and found that they were redshifted. From this observation, Hubble derived the relationship between the distance to a galaxy and its radial velocity, which provided evidence for the expansion of the universe predicted by Einstein Later, English Theoretical Physicist Stephen Hawking , in his collaboration with Roger Penrose, developed the singularity theorem for his doctoral thesis, which predicted the existence of the singularities in the universe, This theorem also suggested that the universe may have started as a singularity...
