That is my contention. What went BANG in the beginning?
Yup!
Read the books by Brian Greene. He has a knack for making these things a “LITTLE” less obscure. He can certainly explain things better than me!
The theory currently is that due to quantum fluctuations, what was, became what is. Or, there was a clash of the braines that are the multiverse, or, just the primordial atom became unstable and bang.
You can’t get much better with quantum physics. :)
