The Big Bang Theory is a scientific theory of the origins of the universe. Evidence for it includes the CMBR (Cosmic Microwave Background Radiation), the ratio of the elements (all matter is the universe is about 75% hydrogen, 21% helium, and 4% other), and the redshift of distant galaxies (redshift is when an object moving away from you is so fast and/or so far away that its color shifts to the red side of the electromagnetic spectrum).
The Big Bang model predicts the universe to be 13.7 billion years old. Observations hold true to this is some of the farthest objects we've seen are about 11 billion light-years away.

I think it's a theory that there was this enormous explosion that formed all the stars, planets and every little bit of the universe at which all living creatures later evolved from there. "The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions."

the big bang theory is an effort to explain what happened at the very beginning of our universe. according to the theory, our universe sprang into existence as a singularity around 13.7 billions years ago.singularities are thought to be zones of infinite density and are known to exist at the core of a black hole.prior to that moment there was nothing; during and after that there was something; our universe.

to sum it up, we needed a theory to explain how the universe came to be, and why everything is still zooming apart from eachother. So, some guy, I forget who, came up with the theory that at one point in time, around 350 billion years ago, all the universe's matter was compounded into a teeny tiny ball, which would have imense density. The stuff in this ball eventually exploded, hurtling all its matter outward, hence creating the universe, and explaining why its contents are still expanding.

I think the big bang was followed by the big O.

There is a big blast in the universe & the masses started going apart from each other
