Is the idea of parallel universes unfounded? How do we know

They exist and are full of waifus who love us.

Thank you analytical philosophy.

Depends on whether you believe there are infinite other universes

>>575743

everyone lives in a paralLel universe since everyone perceives different realities.

I am not sure how this is history nor humanities.

>>575743
depends on what model of physics you're using
our dank standard model doesn't really have a good way to make it work, although the idea isn't necessarily precluded.
spicy string theory seems to tell us that a number of parallel verses exist, but no core theory or fact of string theory has ever been proven in a rigorous sense. the math works, but you can explain a geocentric model of the solar system and force the math to "work" -- that doesn't make it right though.
also in almost all cases, the idea that parallel verses exist is almost meaningless. for the most part, they're not alternate histories, they're alternate physical realities, ie. different physics -- not "lel the alternate world where Hitler cured cancer." there are a handful of people who think that alternate verses spin off from "decisions" (which they routinely fail to define in a way that explains what free will is and why it creates alternate timelines), and also some who think the same concerning uncertainty/quantum effects. that would mean there is an infinite number of verses, but again there rarely is an explanation why they spin off in the first place.
an additional idea is that our universe is the one that's stable. its physical laws hold together, while the spin off verses crumbled apart in a kind of cosmic evolution. it implies other stable verses might exist with altered physics. again, it lacks a genesis hypothesis, but it's an interesting idea. to my knowledge, no-one has really pursued it.

If there are unlimited parallel universes, there is one in which the theory of parallel universes is unfounded.

So it is unfounded

>>575743
Its is just a common fantasy of man. People dwell on past events and wonder at the possibilities if something different was done in the past.

So, unfounded and impossible to know if they exist.

Fucking retard. Many worlds is completely independent of string theory. Guess which one says anything about parallel universes.

MW an attempt to do away with quantum decoherence with mathematical wankery which impressed neither the physicists nor the mathematicians; and you, being the gullible idiot that many are, doesn't care about being factually correct but instead conflates two "smart-sounding" things so that you can appear intellectual on a Siberian donkey fisting bulltein board. Absolutely typical.

If we steer it into modal realism and waifus, then it's philosophy.

From a scientific perspective Parallel Universes are idiotic. If they exist they are distant in such a way we are unable of ever interacting with them. And by that I mean we can never even detect them. They may as well not be real.
There is no way to test for their existence, and so until we find some way to do so they're as good as fake.

Go to /sci/, we're being pseudo-intellectual here

Do people in other universes go to the same afterlife as us or a parallel afterlife?

>>576101
Detecting rainbow gravity or gravitational waves would give us a strong hint that they exist

Problem with infinite universes, is if there's any interaction between them, at all, then every universe would be filled with an infinite amount of energy generated by an infinite number of interactions, and I wouldn't be here to bump this shitpost thread.

So either there's a finite number of universes (such as 1), or there's an infinite number of universes, but no interaction between them is possible, so it doesn't matter.

>>576101
So... The unobservable universe doesn't exist?

Hey, we're almost actually in /his/ territory now!

Granted, in about 100 billion years, due the accelerating expansion of the universe, you'll be able to say the same of every galaxy we see today (save Andromeda) and the microwave background radiation.

There'll be no evidence of the big bang, or anything outside this galaxy. Thus, the universe, as we know it now, is as good as fake.

Which kinda makes ya wonder what else we might be missing out on in the meantime for the same reason.

Sadly, I believe this. The reasonable alternative I can think of is that some "universes" are contained inside other universes (think simulations).
