1. I think I saw someone say that the Big Bang was something from nothing.
How exactly do we know there was nothing? Anything from before would have been completely and utterly remade during the Big Bang.
2. As for the explanation for the Big Bang, I have my own thoughts.
My physics teacher in my senior year of high school told us about the theory in which the end of the universe will be caused because of heat. Slowly, as more and more stars give off heat into the cosmos, the universe will grow warmer and warmer until nothing can survive. The universe will essentially boil itself. (Or something like that).
Well, massive amounts of energy would be necessary for a Big Bang, right? What if the build-up of heat energy is what will trigger another Big Bang? What if the previous Big Bang was caused by the same energy build up?
