Infinity

[fdesilva]

The law of conservation of energy, that is all laws of physics, all energy all space and all time came into existence at this event the big bang. So energy did get created at the big bang

We don't know that. All we know is that all the energy in the universe was in a particular state at the Big Bang The universe may have been in a completely different state beforehand. The universe may be cyclical, contracting and expanding. It may be that this universe was created when a star went supernovae, created a black hole all it's energy got sucked into a really small point and created a new bubble. Fact is, no one knows.

At the big bang the laws of physics do not exist. That is why its called a singularity. You do not have a before hand as time itself was created at this event. These are the accepted facts, not something I am making up

Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.[13] This singularity signals the breakdown of general relativity and thus, all the laws of physics.
