I've not read the article, but I have watched documentaries about the universe and this is a subject that came up in a few of them. Kind of wild. And these were not questionable scientists, these were well known respected astrophysicists. I'm book marking it for reading tomorrow.
I just read a New Scientist article about the Multiverse -- the quantum-linked theory that there are an infinite number of universes, each one inhabited by an equally infinite number of Didges? It sounds whacked out to me but I know that many scientists believe it to be literally true. I lack the education to make any realistic judgement. Would some of you care to check the link and comment, please? https://www.newscientist.com/article/mg22329880-400-multiverse-me-should-i-care-about-my-other-selves
