No doubt Stephen Hawking is a lot smarter than me but why would a self contained universe have to be creatorless? Only means that the creator of space/time exists beyond it. I understand that is a difficult concept to embrace.
It's not difficult.. The creatorless-universe may be just one of an infinite recession/series of intermediate steps to "creation" which some unimaginable "Creator" sparked off eons ago. Picking the one we lowly humans (as we are now) can detect NOW, as the one final conclusive "proof" of supernatural/godly fingerprint, is pretty shortsighted.

I'm sure he'll have a sense of humor, and disposing of an eternity and infinite Goodness, will allow for the time to go for a beer or two to shoot the poop before sending me to hell in eternal damnation.
From within the perspective of space/time, it always was and always will be. Without space/time how could there be any thing, beginning, or end? A question is can there be a continuation or event without space/time as we know it? I believe the answer is a qualified yes, it won't be an existence we can understand from within our perspective of space/time.
Anthropomorphism. 2000 years ago, we wouldn't have understood jack of what what today's average joe does... Everyday happenstances 2000 years from now will be explonentialy more out of reach from us.. space/time may well be some tired old paradigm. etc.
