If multiverse theory was true and infinite, there would be a universe where someone figured out how to destroy every universe.

🀫 Don't.

Ah, but there would be another where someone anticipated this and figured out how to stop it.

Of course that then suggests a universe where a madman figured out how to destroy the multiverse and keep it from being stopped, and one where a dogooder anticipated that...

Such a multiverse could end up existing in a state of indeterminate existance. Like a certain cat...

Only if destroying every universe were possible

Lol, good joke but wrong, even existing an infinite number of Universe, to be stables they need a infinite number of physical conditions, if not they can't exist. A multiverse, even if there are formong an infinite number of universes, most of them are destroyed in the same moment when are not present this conditions, even so it can exist an infinite number of survivor universes with the correct conditions (∞/n = ∞), paradox conditions are not among these (apart of the infinite itself, used in physics)

there is a universe full to the brim with chickens, all that chicken space.

I love multiverse theory! I also love how a lot of people don't really understand how finite infinites work in the context of multiverse theory!

There might be a universe in which magic exists. However, there is no universe in which I exist and magic exists. That's because I was born into a mundane version of the universe, so there are infinite possibilities, but because my existence in a magical universe is 0, being accepted into a witching school is something that'll never happen for me.

So no, within the context of multiverse theory there is no universe in which multiverse theory doesn't exist, because that is a paradox and as such, has 0 chance of existing. However, it totally possible that a magical universe does exist (I would say we don't know enough about the formation of the universe to accurately judge whether or not such a universe could be possible under the right formative circumstances); it's just that the chances of any of us existing in that universe is 0.

huh

isn't this just Russell's paradox

wikipedia

if I recall correctly Russell's Paradox was how ZFC set theory became the standard set theory

ZF handles it. The C adds the axiom of choice. But ZF is enough for dealing with the Russel paradox. Oddly enough, Zermelo, the Z in ZF, published the Russel paradox a year before Russel.

There's a parallel universe in which the fundamental laws of physics are different: the weight of an electron, the gravitational constant, how many fundamental particles there are, the cosmological constant, ...

And one where I have a goatee and I'm the evil version of myself, right??

You're getting into omniverse territory here, I think. But if accurate, then the dimensions without multiverses just lack the ability to perceive, observe, understand, measure, prove, or travel outside of their own universes. There's a whole multiverse of such isolated bubbles that will "know" that there's no multiverse, and we have a 50/50 chance of being in one.

That’s not how statistics works lol

[–] groet@infosec.pub 4 points 1 week ago (7 children)

If there are infinite universes, covering all permutations of all properties (i asume thats what they mean by omniverse), then there will be exactly as many universes with a certain property then there are without it. So it is actually 50/50.

In the "multiverse of all possibilities" there will be 50% without a multiverse
