I have seen this Ted Talk before. There is no physical or observable evidence for a multiverse or multiverse generator. Even if there was, it doesn't explain the origins of either. It's pure speculation. The fine-tuning of the known Universe is scientific fact.
@Himanshu_agarwal I have thought about this before and I have accumulated my own theory. Haha :D it sounds weird though, for me.. it seems like we're a bacteria living in a human body (giant) , we scatter , we reproduce , we die, we are monitored. The sun is like a light from a huge room , there is something or someone who make sure we're moving and reproducing. I dunno really why I've thought of something like this..
