COSMIC BEGINNINGS
We on Earth think of the universe as a vastness containing everything we know of -and much that we cannot even imagine . For millennia, humans have struggled to make sense of what they see all around of them . They have observed, calculated ,and conjectured, trying to articulate an explanation for a puzzle whose pieces are slowly being revealed with each scientific breakthrough.
The investigations of astronomy, astrophysics, and mathematics join the cosmological inquiries of seeking minds in all cultures and all time those of philosophers, scientists, religious scholars, poets. Questions about the universe always involved beginnings and endings. Now science is finding answers to questions long answered only by means of myth.

What Is Big Bang
What Is Big Bang
Accepted astrophysical theories posit that one point there was nothing ; no stars, planets, or galaxies - not even space itself. The matter that makes up everything that now exists was concentrated in a single, extremely dense point known as a singularity.
The force of gravity in a singularity is so great that the fabric of spacetime curves in on itself . In an instant known as the big bang, however, the contents of the primordial singularity escaped- and formed the universe.
This is Big Bang
