GENERAL KNOWLEDGE

Detailed explanation-1: -The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.

Detailed explanation-2: -The Big Bang: the birth of the universe Around 13.7 billion years ago, everything in the entire universe was condensed in an infinitesimally small singularity, a point of infinite denseness and heat. Suddenly, an explosive expansion began, ballooning our universe outwards faster than the speed of light.

Detailed explanation-3: -The Big Bang has no center. It is not an explosion radiating from a point. In an explosion you get an expanding spherical shell of fragments as shown below: This shell has both an outer and an inner edge, and these can be used to locate the position of the explosion.

Detailed explanation-4: -In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.
