I recently watched another program with Stephen Hawking called "Did God Create The Universe?" However this topic isn't religion related but my questions popped up due to this. I am having problem understanding how the universe could pop up from nothing when time did not exist. They said this was possible due to (quantum mechanics if I remember right?) particles (they said particles like protons) popping up into existence and also disappearing shortly after that. However, how can a particle pop up into existence, when time did not exist? They also proudly mentioned "Since time did not exist, there was no time to cause to happen, and since no cause could happen, god could not be the creator of the universe" something like that. I hope you understand my question, I find it always a challenge to ask these deep cosmology questions as well as understanding the answers to them! Regards, Robin Andersson.
