Great interview/conversation.  However, as far as we know, the hypothesized big bang cataclysmic event that presumably set everything in our experience in motion, and expanding at very large scales, might not be the origin of THE universe, but maybe just a relatively tiny disturbance in a much larger, and perhaps infinite, universe.  In any case, it doesn't matter.  But it is fun to speculate about it sometimes.  Thanks for your channel and videos.  Good stuff!
