The Multiverse (video)
I’ve uploaded another video: https://youtu.be/Wwo9xtzzxe8
TL;DW: Some physicists think that our universe is one of many (probably infinitely many) parallel universes. I talk about Max Tegmark's views on this, from his Scientific American article. Given an infinite multiverse, you should expect that everything that is physically possible (and has nonzero probability) occurs somewhere out there ... in fact, infinitely many times. E.g., there is a duplicate of you in some far away universe, etc.
