We are in a Black Hole

As much as it pains me to stick up for mattemuse, he has actually gone back on that stance.

I’m going to be perfectly clear here, this response will be totally grounded in nothing other than pure speculation.

I think the alternate universes occupy the same dimensions as ours. (“dimensions” could just be the base units of the “multiverse” if you were to somehow observe it from “outside” any of the individual universes.) It’s my understanding that our universe occupies all dimensions, it’s only that we can perceive a limited set. In fact all universes would tend to be highly similar in every aspect, because the initial conditions leading to creation are likely virtually identical from black hole to black hole . It’s entertaining to conceive of alternate universes that are 100% identical to ours, i.e. billions of alternate “mattemuse” are now typing the same response in different universes, but quantum randomness probably (but not definitely) precludes this from happening. I lost my train of thought, here, so much for that.

Another way of interpreting it is that, for a black hole in our universe, another universe is literally contained within the spacial (3-dimensional) boundaries of that black hole. The articles referenced in the OP refer to the multiverse as being like one of those russian dolls with more dolls inside it, but I have no idea if the analogy is supposed to be taken literally in the spacial sense or or not.
Since nothing can enter or leave, the space “inside” those 3 dimensions can become infinitely larger within that finite space, since it’s impossible to breach the boundary. I don’t know why, but it intuitively makes sense that infinite expansion within a finite space would account for the fact that, since our universe is expanding at a constant rate without slowing down, in a few million (billion?) years, the space between individual atoms in a human body is going to be literally hundreds of miles apart in today’s terms, but the subjective experience of that human would probably be identical to ours (assuming any humans are left at that point).

I’m accepting it as valid (note: not the same as “fact”) because there is evidence it is fact (the math behind it) and no evidence which suggests it isn’t valid. At the time it’s invalidated either mathematically or evidentially, I’ll have no problem whatsoever accepting whatever theory replaces it as the best guess at the time. The discussion of when a scientific theory becomes a fact (even after evidence is found supporting it, there’s always a chance that an exception will be discovered that disproves it) is I’m sure a contentious one even among scientists, so I’m open to other perspectives on it. The only thing I’m taking issue with is people denying there is any evidence to support the theory when its been mathematically proven.

That’s pretty much what I was trying to say, if I understand you correctly.
Using an analogy, two different universes would be like two different lines (4D lines) in a plane (5D plane).
As for our universe occupying all the dimensions; that is indeed the case, but the higher dimensions (starting from the fifth) also contain other universes.
At a 4D level, there is our universe (or any universe for that matter). At a 5D level, there are all universes with the same starting conditions. Something like that.
I know I have linked it before, and I’m not sure if you’ve watched it yet, but this does a great job of explaining how to imagine the dimensions. This model is being supported by scientists, so I think it’s reliable.

I don’t think the russian doll analogy is to be taken quite as literally as that. One of the articles (the NG one I think) refers to the black holes as having wormholes in them, which is then a “portal” into another universe (probably within our “instance” of the fifth dimension).

As far as I understand it, when we’re talking about different universes, expansion is irrelevant, since at that point we have to consider the universes at a 4D level, i.e. from the “beginning” to the “end”.
Time is subjective to human perception (“time does not exist”) and therefore so is expansion.

They never mention other dimensions in the articles. 3d matter can’t become 4d.

I don’t think we’re on the same page, the way I understand dimension theory, it’s not that a particular universe occupies a particular “level” of dimensionality - they are encompassed by all dimensions. Objects in our universe have the property of length, width, height, 4, 5, 6, 7, and so on, the fact that we can only perceive the first 3 isn’t relevant to the fundamental nature of reality. Maybe 8,9,and 10 are the equivalent of length, width, height in the multiverse, but that doesn’t mean objects in a particular universe don’t also have those properties.

They never mention dimensions in the article because at the current state of our scientific knowledge, relativistic physics is totally incompatible with whatever kind of physics you’d call multi-dimension theory. There’s a ton of research being done to combine the two, but as of right now we can’t do it.

I think you misunderstood me. I didn’t mean that a particular universe occupies a particular level of dimensionality.
I meant that in a four-dimensional continuum (space-time) there is only one (any) universe, whereas if you look at the bigger picture (five dimensions or more) there is any number of universes.
In other words, if you look at four dimensions (like humans do), you’ll only see one universe. If you look at five or more dimensions, you’ll see that one particular universe and other universes.
This means that any universe occupies all the dimensions, but the higher dimensions also contain other universes.

In this theory, black holes could be considered a five-dimensional “direction”. However, since humans are tied to four dimensions (only one four-dimensional direction, time, at that), it is impossible to go in that direction, since it would take an infinite amount of time.

I wish man could travel to other galaxies without using 100.000years (or something like that)… but it shows up, It is impossible, you can’t break the speed limit of space AKA: the speed of light! (epic cliff-hanger music, please)

fuck off, that’s not even relevant

Dear god, please leave.

I guess I did misunderstand - if I’m getting you correctly, it’s an interesting idea. A alternative interpretation would be that the dimensions themselves are properties of universes, and are created as a result of the white-hole “big-bangs” that create the universes. In other words, they aren’t fundamental properties of the multiverse, but are created along with every other universal property as matter inverts itself inside a black hole. I’m leaning in this direction although I haven’t given it too much thought.

I think any scientific progress as far as dimension theory goes will be something interesting to look out for in the near future.

Damn me and my “most… make… comment…”-thought-syndrome-thingy! This makes my comments just more and more stupid!

Did you know that the no two experiments have ever given identical values for the supposedly “constant” speed of light? In fact, since it was first determined, there is a consistent upwards trend, i.e. the speed of light is getting faster as the universe expands.

Also, some interactions on the quantum level happen faster than the speed of light.

That’s it I’m out of here before I do any more damage!

And if I’m not mistaken there is some sort of radiation (can’t remember what exactly), that escapes black holes.

Besides, it’s common sense that any aliens supposedly visiting earth would have some sort of technology that allows them to overcome limitations of speed.

I think it’s high energy electromagnetic radiation that can escape. If it has enough energy it can spontaneously turn into a quark and an anti-quark (I think those are the particles). One gets sucked in and the other is sent shooting out into space.

If that’s not cool enough, if a binary system gets too close to a black hole, the same thing happens with fucking suns.

Also, light changes speed in different mediums meaning that depending on the location, it’s not too hard to get to FTL speeds. Hence Cherenkov radiation.

IM BACK AND IM GOING TO STAY!!!

Stay Banned

Reminds me of the Futurama episode where they have alternate universes in a box.

Then you got a black ass hole.
Wait…
That didnt come out right.

nobody got that and i am slightly disappointed
