>>12195424The idea starts with: Infinite universes.
The idea that, at every possible decision point/wave collapse of QM, multiple universes are split off, each universe a different "Decision". This is based on some loosey-goosey interpretation of quantum mechanics. It's not outright a bad idea, but you can see how pop-sci takes this and runs with it.
So, you can imagine that this leads to uncountably many universes. Two universes may be identical except one blade of grass has an atom which radioactively decays at timepoint T where the other universe, it does not, etc.
So the idea is that, because there are infinitely many "universes", and they cover every possible scenario in existence, that there exists at least one universe where you live forever, or at least until whatever the laws of physics allows, no matter how improbable.
All of this is fine so far. This is the general form of quantum immortality. That a version of you, somewhere, is sorta immortal, in one of the infinite universes.
Now, the stupid part.
Somehow this turned into "you cannot die because your consciousness will only exist in the universe that you don't die it, so you won't ever experience death, since your consciousness will just live on in the universe where you live". It ignores the fact that yes, in many of the universes, you fucking die if you jump off a 50 story building, and your consciousness does not live on.
