In an alternate universe the Niners are -2 tomorrow. Find a way there and slam SF -2.

Wow.

For the record I just found this video a couple minutes ago.

Well, that video does a pretty good job showing the problems with Multiverse "theory," but I suspect without some basic understanding of quantum mechanics, and at least a moderate understanding of the principles of science, most people wouldn't catch on.

Luckily, Einstein, Bohr, Heisenberg, Pauli, Bohm, et al. wrote volumes detailing their personal debates with one another (and others in the field) regarding the invalidity of the Infinite Worlds model. The dialogues between Bohr and Einstein are the most worthwhile reading. FYI... nothing about the Infinite Worlds theory/model has advanced since their discussions roughly 80 years ago. Experiments in quantum mechanics as recently as 2021 in Australia have continued to confirm the Copenhagen interpretation of Quantum theory, and no experiments in the field of quantum mechanics have (a) ever done anything other than confirm that interpretation, or (b) lent any credence to Multiverse "theory"

Incidentally, I put theory in quotes, because Multiverse theory does not qualify as a scientific theory, by virtue of the fact that it is unfalsifiable, and (by any reasonable measure) also unverifiable. There are, of course, other problems, but I have no interest in summarizing the works of the men who discovered the nature of quantum objects, or defined the terms of quantum theory.

However, Sabine Hossenfelder (Ph.D in Physics and M.A. in Mathematics from Frankfurt University), has made a simple video explaining why the Multiverse is not a credible scientific theory.

Now, the good news is that, according to Multiverse theory, there exists a universe where Multiverse theory actually constitutes a credible view of reality, rather than just a religion for atheists, or a clever idea that lets stupid people pretend they understand quantum physics. Unfortunately, we're not living in that universe.
