I guess I’ve always been confused by the Many Worlds Interpretation of Quantum Physics and the fact that it’s taken seriously. Like is there any proof at all that universes outside of our own exist?

I admit that I might be dumb, but, how does one look at atoms and say “My God! There must be many worlds than just our one?”

I just never understood how Many Worlds Interpretation was valid, with my, admittedly limited understanding, it just seemed to be a wild guess no more strange than a lot things we consider too outlandish to humor.

    I don’t think it proves many worlds any more than it proves you have a fairy godmother manipulating quantum states for you. All you’ve done is shown an unlikely occurrence happened, not what caused it.

      All you’ve done is shown an unlikely occurrence happened…

      That’s all science is. Collect data, and show how it’s unlilely unless your hypothesis is true. Five sigma later, and you’ve made a discovery.

        Collect data, and show how it’s unlilely unless your hypothesis is true.

        The quantum immortality experiment doesn’t do that, though. The outcome, by definition, always occurs within the realm of random chance. Your environment needs to create an outcome that is extremely unlikely to occur by random chance. The experiment is not repeatable. It makes no predictions about what’s going to happen if you try again. It doesn’t do anything useful to bolster the many worlds theory.

          If you survive 32 half lives, I’d call that extremely unlikely! Give a try.

            The experiment, as defined, only leads to your survival by random chance. The experiment does not create any outcome except by random chance so it cannot be used to prove anything.

                The chance you’ll survive a half life is exactly the same whether MWI is real or not. It doesn’t give you any useful information. You have no way of distinguishing between being just that lucky or MWI being true.

                That’s not the case with other experiments. If you assume your hypothesis is correct, the chance of the experiment being successful is higher than the chance of it happening by random chance if your hypothesis is not. That’s a key difference.
