Multiverse Question

[CrazyGirl17]

I like the concept... but the technical details make my brain ache. For instance, if any choice leading to any alternate outcome leads to an alternate universe, shouldn't there be like billions of them? Or do some of them fold into other alternate time lines?

...Gah....

You can't reach parallel universes. It's a fundamental law of the theorem. Take heart in the fact that in one of those universe a parallel you tired and failed though.

It is theoretically possible to enter a black hole and by avoiding the singularity then enter into and be expelled from a white hole into another universe.

Okay, you go jump in that black hole. Have fun with relativity and ensuing time dilation causing you to take millions of years to pass through. Also, have fun traveling faster then light to get out.

Firstly I said it was theoretically possible, not plausible. Secondly if I could be the first person to successfully explore a black hole beyond the event horizon, and somehow returned unharmed possibly in my present (since the event horizon of the white hole will take you to the past) then I would, and I'd be a hero for doing so and some kind of super space badass If I happen to explore an alternate reality as well.

The whole multiverse thing is almost certainly bullshit. The whole concept is incredibly silly, with no basis in fact, theory or even logic.

Each parallel universe is supposed to be the same with only a slight change between them, so it could be that those universes don't have that kind of technology either. Or, it could be that they went to every other parallel universe except this one.

If you make a slight change between universe 1 and 2, then another between 2 and 3, and so on and so forth, eventually you will reach a universe that shares absolutely 0 commonalities with universe 1. If there are an infinite number of parallel universes, at least one has come up with the way to travel between them. And since there are infinitely many parallel universes, there are infinitely many who have such technology. Thus, we can conclude that there have been infinite visits to every universe. As such, they have visited our universe.

The multiverse theory is complete bullshit, Hollywood science at it's absolute worst, made worse by the fact that so many people actually believe it's true. It would be acceptable if it was a religious theory, at least that way it could take refuge in theology, but it's presented as scientific when it's anything but.

I don't think you've quite grasped the meaning of infinity, at least that's what it looks like. Simply put it doesn't work like that. If you have an infinite amount of universes and a infinite subset of those who can 'hop' between the verses there will still be an infinite amount of universes that have never had any outside visitors. Look up the Hilbert Hotel example, it explains it well.

Also, Occam's Razor does not work that way and simplicity =/= a single universe.

I would think the laws of physics would stop travel between Multiverses. Namely the laws of Thermodynamics because the Universe is a closed system, and travel between would require a gain/loss in the total amount of energy contained in that system.

Unless you simply switch places with an alternate "you". Then the law of conservation of matter isn't broken. And there are no paradoxical effects causing event-horizons. The universe works like Windows. If there's an error, it crashes. Black Hole = system crash.
