I have watched the video on this post for quite a lot of times and I still can't figure why people can conclusively say time does not exist before the big bang.http://blog.tsemtulku.com/tsem-tulku-ri ... tions.html
Science is the new religion
I suppose my opinion about this is that, could it be possible there is more than one big bang in the entire 'neverending' universe? I mean the big bang where our universe is in, at the time of the big bang for our current part of the universe, another big bang had already been activated or started already. I may not be making sense would appreciate people's views on this.
I've heard theories like that. There several different "multi big bang" theories. However, as scientists can't even measure the size of the universe, all these theories are mostly guesses.
