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'm not sure that there is proof. But there are quantum effects like wave function collapse, what a wave or particle seems to exist in multiple ways until measured.

That's kind of out dated...

Like, physics has been fucking crazy the past couple years.

It looks more like the right answer is "both" these days.

Like, the OG double slit experiment was 1801, we just did a new using individuals atoms as slits and individual photons, with measurements taking only a millionith of a second.

Old experiments just didn't have the mechanisms for further testing.

It's like that time we "proved" that a body takes action before the brain sends instructions, and really we're just rationalizing things the body does autonomously... Which, was really fucking huge.

Then we realized that we just didn't have the tech to measure it, and while the brain will rationalize actions, that's not what's happening 24/7.

The problem is there's constantly new discoveries with this shit, but most people just stick with a simplified version they learned in science class.

I hadn't heard about a recent double slit experiment, I'd love to know more. If you have a link, or some info about where it was done, I'd be grateful.

And what's the autonomous body reaction stuff? I'm curious about that too (which I'd always assumed anyway, but if there's research I'd like to read about it).

Thanks!

I had a though experience years ago on mushrooms, that our universe lives in a blackhole. Just think about it, when stars big enough implodes it creates a black hole in the fabric of space, where nothing can escape (not even light).

The beginning of our universe is somehow related to a condensed hot/light that explodes and creates the actual expansion we see right now... Kinda curious right?

Also there's somehow a limit how far we can see through our universe, that's also odd... It's impossible at the moment to see outside our own universe, because remember nothing can escape outside a blackhole, not even light !! Soo yeaah that's why I think we live in a multiverse.

Also on a final note, Rick&Morty said so 🤷‍♂️

An analogy, if you're into programming, is that when the universe splits it will not duplicate the code of the universe but rather branch the state out.

Still though the universe would need some endless amount of memory to handle all the different deltas.

You're asking a couple different questions at once...

But basically assume that there are multiple (maybe infinite) big bangs, and each time that happens, the resulting universe has its own laws of physics. We wouldn't see slight changes, things would be drastically different, but since they keep popping up. Eventually we'll see every permeation happen. Including identical everything to ours, but just one random difference that created the TV version of alternate realities.

You might think entropy prevents that, but "entropy can't be reversed" is less a fact and more "the simplified version laypeople are told in science class".

And a different option would be that rather than one straight line of time, any possible choice can branch and create its own timeline that can then branch, etc.

And that might seem like we're "stuck" but nothing in physics even requires one way direction of time. The only reason we need to perceive it in only that way, is without linear time consciousness couldn't happen. Without cause and effect, consciousness can't exist
