You're not listening are you? I'm not religious.
The Big Bang has NOT BEEN PROVEN. It's a THEORY.
Now, I'm working on the basis here that the Big Bang happened, but it wasn't the beginning. That all energy goes around in a cycle, it reaches a point where it all meets in one dense super hot place and it then bangs, explodes and that then becomes the start of a new cycle. It then flies off, cools down, turns into atoms and the like, and then becomes galaxies and planets and stars.
We know our galaxy is moving, we know our supercluster is moving. All things are constantly moving, and things are moving towards each other. We know black holes exist, take in energy and don't let it escape. Well, what happens when superclusters all end up at the same place? I'd assume a super massive black hole the mass of millions of galaxies.
And then what happens when ALL THE ENERGY in the universe is in one place?
Where the evidence of what existed before all the energy ended up in once place? Well, it's all in the same place, isn't it? You wouldn't be able to see the light, because it's not light any more. You wouldn't be able to see the radiation either, because it would just be a part of this super hot, super dense thing.
