A few questions... 1. An immense amount of energy would be needed to create an "explosion" such as the big bang. My question is, where did this energy come from? I find it hard to visualize something when time, matter, and space didn't exist. 2. If nothing (time, matter) existed prior to the theoretical 'Big Bang' and all energy existed in a single point, then wouldn't that mean that 'empty space' as we know it today has been expanding since that point in time? If true, wouldn't that mean that it is not infinite and will become larger and larger forever? And a side question: Can(will) time end?
