If the Big Bang is accpeted as the best explanation to the beginning of the universe and that the universe is expanding constantly, how does infinity factor into the equation?
First of all, the universe has to expand into some sort of vacant space, and if the universe is finite what is outside of the boundries?
Also if the sun is a giant ball of flame, what happened to spark the fire in the first place? Doesn't fire need O2 to sustain it?
