The following video is the most instructive one I have yet seen on the topic of alternate and parallel universes, the multiverse, quantum entanglement. The fact that is has over five million downloads is what first caught my eye, and now I can see why. It features physicists from world-famous institutions making their points so clearly that practically anyone can understand them. If you have an hour to spare and would like to catch up with thie exciting new developments in quantum physics, I heartily recommend iit!
The video also illustrates the conceptuall framework for the book which I wrote with Kelley Woods entitled, Virtual reality hypnosis: Exploring alternate and parallel universes. Amazon Books, 2016. (Both print and Kindle editions are available.) (Gibbons & Woods, 2016)
