God vs. Science

[Maniac1]

I am simply asking you to establish where the matter that was involved in the Big Bang came from. Or do you deny the existence of the 1st law?

Theoretical couldn't the big bang be an ever lasting cycle, repeating over and over again? Since matter is now expanding farther away, it should come to a point where matter starts absorbing each other due to gravity, right? And over trillions and trillions of years start forming into another energy orb gaining energy every second til it's density becomes so dense and gains infinite mass then one day re-explodes. This explosion would be even greater than gamma ray bursts, so could this be how big bangs occur? Would this even be possible, or do any laws prevent this theory from existing?
