What is the big bang theory and how does it explain the formation of the universe?

There is no way to find out if there even was a universe before , therefore no one knows the answer on your question. We don't even know how big...

My estimate is attributed to other estimates. Our universe has had expanded through 13.8 billion light years in 13.8 billion years. So, I have reference for okaying my estimate.....

It is theorized that at the moment of energy was contained in a singularity which means there is no space-time.

The Big Bang Theory implies that our present universe had a beginning. Oddly there was a time when there was no time. The outward expansion matter created both time and...

Not to oversimplify this but the very nature of "theory" means that an absolute proof does not exist. In the case of the development of the early universe, it will...

Even determining "facts" is a difficult, on-going process, with many errors along the way. BUT, the point of the "Scientific Method" is to KEEP questioning and looking for supporting EVIDENCE,...

This is a question that still lies outside of our knowledge, and may always continue to do so. Physics today can do a creditable job of outline the events that...

Edwin Hubble observed in the early 1900s that the Universe exhibited a marked red shift. Objects that have a red doppler shift are moving away from the observer. This lead...

Edwin Hubble found out by the study of septum that Galaxies are receding fro m us from each other by red shift . George Gamow predicted that the remnants...

The Big Bang means that the Universe evolved from a singularity and the Universe is inflationary, it being finite and unbounded, Einstein had originally postulated the need for a cosmological...
