Detailed explanation-1: -The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. But what caused this explosion in the first place is still a mystery.
Detailed explanation-2: -Today, the Big Bang theory is the most accepted explanation for the origin of the universe. However, some have called the Big Bang theory false. Sadly, theories are all we have since it is not possible to travel back in time and see how the universe actually originated.
Detailed explanation-3: -The standard big bang model cannot explain why the Universe started out so flat. We call this the flatness problem. Distant galaxies are redshifted. The Universe is expanding.
