Here I am summarizing the video:
1 .Double slit experiment
I'm not convinced that's evidence of "alternate realities". I'm most emphatically
not a quantum physicist, but my favored layman's interpretation of the double slit experiment is that unactualized possibilities do have some kind of physical reality. Hence a photon can go through one slit and interact with the
possibility that it might have gone through the other slit so as to produce an interference pattern.
I'm not sure whether that qualifies as an 'alternate reality' theory. It isn't a full-blown many worlds multiverse idea of the modal realism sort. It's more like early David Bohm and his 'pilot waves', where actual reality is surrounded by a cloud of unactualized possibility states corresponding to ways that things might have been, that subtly interact with physical reality and perhaps arguably guide it in whatever ways Bohm imagined his pilot waves doing.
Or something like that...
Only suggest the existence of unknown explanations, not necessarily alternative realities.
I'm not sure what that refers to.
4.Supernatural activity(meaning,ghosts may be beings from another universes)
I don't believe in ghosts, though I do accept that unexplained phenomena can and probably do occur. (Even that idea gets me flamed on Sciforums.) But it's still a huge leap from unexplained phenomena to alternative realities.
Would be time, wouldn't it? Not to say that time isn't exceedingly mysterious.
But sure, I can imagine additional spatial dimensions that we are totally unaware of. I can imagine being locked in a totally sealed room and kind of stepping...
sideways... in some incomprehensible way out of the room.
I have no way of knowing whether any additional spatial dimensions like that exist though, so it's totally speculative. It's conceivable though that physics might find some theoretical use for them though (
it already has to some extent), some future experiment might verify their existence, and physics might someday provide some means of accessing them.
What's the relevance to alternative realities?
7.Dreams(claiming that we visit parallel universes in dreams)
I realize that many cultures have traditionally interpreted dreams that way. But I don't. Most of my dreams (what I can remember of them, which typically isn't much since they fade rapidly) seem to consist of scraps of memory from my waking life, assembled in no particular order with a seeming narrative connecting the parts that rarely makes much sense when I wake up.
I'm inclined to think of that as normal psychological processes at work. We normally try to assemble our experiences into narratives that make sense to us. Science is just one of the ways we do it. So when we are asleep, and memories bubble up, perhaps as part of some process in which they are being read from short term memory and written into long-term storage, the narrative-making function goes to work and tries to generate a story connecting them.
8.The visitor from Taured
9.Lerina Garcia Gordo( woman who claimed to be from another universe)
10.Alter Vu and Mandella Effect
I have no idea what these mean (and I'm too lazy to google them).
