Space just got like, deep, man.

[Atlasion]

I don't know much about space or anything (it confuses the hell out of me) but hearing that a black hole could contain another universe, not just connected to one, is new to me. That universe would just be compressed down or something. Like in Men in Black.

[Drinhkinn]

If our universe was a black hole for another universe, then wouldn't we be able to find an "entrance" point where we can observe incoming light from the universe we are a black hole of?

Accounting into fact that the closer you get to a black hole, the slower time gets, couldn't be theorized that at the exit point of a black hole, all the matter it has/will ever accumulate will come out in that new universe all at once, creating a big bang?

I mean hell, we're dealing with theories, so this is as likely as anything else.

[Not Kuno]

You wouldn't be able to go inside it anyway. Because you know, the whole "your body being stretched out till you're a long strip of molecules" because of the gravity associated with black holes. If you can fix the whole "dead instantly" thing, it would be interesting to go.

[Koga]

Isn't there some labortory in Europe that has the ability to manufacture microscopic black holes that last for like a second or two or something like that?

[VZX]

Why did I think their definition of wormhole = my definition of black hole and vice versa?

Is it only me?

AFAIK,

Wormhole: hole in space, enter it on one side, come out the other side wich is at a completely different location instantaneously, while remaining in the same universe.

Black Hole: Gravity implosion, that sucks in every known matter, light&photons included into it's gravity center. Could be interpreted as a wormhole in the sense that there might be an exit point somewhere, but might be in the same universe or most likely a different one, thus explaining why we never discovered the existance of any White Holes. (Theorized to be a black hole exit, where matter appear out of it)

Bottomline, a black hole can be a wormhole, but a wormhole is not a black hole.

Wouldn't the matter just accumulate over really really slowly, not all at once?

[Fhqwghads]

If we are soul-less creatures (which is a very safe assumption imo), then there's nothing preventing our molecules from being ripped apart into a single line, as long as they're put back together again in the exact same way and state (preserving the chemical and electrical signals that make up our memories and personality.) With that said, if there's a theory that black holes are a gateway to other universes, it would be an incredibly exciting prospect, as long as that theory includes a way for material that enters that black hole exiting the black hole in the same state it was prior to entry.

Also an interesting FYI: Black holes don't consume everything forever. They do let photons escape every now and then. Perhaps those are fired from the other side by beings trying to communicate with this universe?

[Drinhkinn]

Hard to tell, really. Time slows down exponentially the closer you get to the core of a black hole. So as matter ends up reaching a point where time plataus to nil (the transit between entry and exit?), matter would just accumulate into a singularity over infinite time and appear at the exit apperture all at once.

Or i may very well be horribly wrong and it comes out slowly off the exit like a stream of matter, but then i dont know how the decompression of time would be handled.

Until the day we find a way to send something safely through a blackhole in a timeframe shorter than infinite, and it have means to communicate back to us from the exit point, we really will never know.

On the plus side, my theory sheds new light on the big bang theory and the creation of our universe. Then again i never took physics at any university, but that's just my understanding of it.

[Kaylia]

Except would these other universes be capable of supporting life? Afterall, all material that passes through, organic or otherwise, would be destroyed. Unless it's possible to take organic material, compress it to a single point, and then after it passes into another open universe, it can gradually decompress over time once the incredible pressure is removed.

If I had to make a guess, I would say our universe is the one in a billion that allow matter to be organized the way it is. I seriously doubt the definition of matter in this universe would be similar to the definition of matter inside a blackhole considering every parameters would be different (lightspeed [assuming there is even photon], gravity, electrical and magnetic force...etc). Take the 1st second that followed the big bang, change anything and you might say goodbye to galaxy or any form of organized matter. "Is it possible for life to appears in a completly different universe?" is still an interesting question, but it's kinda hard to imagine another lifeform. Gravity being? Antispiral being?

If our universe was a black hole for another universe, then wouldn't we be able to find an "entrance" point where we can observe incoming light from the universe we are a black hole of?

The big bang would be the entrance in that kind of model. A black hole is a region of time/space that make a complete circle around its center basically. The definition of time once you're inside would be completly different, and you wouldn't be able to escape it.

[Khamsin]

Given that there's always been the idea of colonizing other planets someday once Earth fills up and technology advances enough, then assuming the multiple universe part is true, perhaps one day we'll discover how to enter and exit the other universes and explore/colonize them, as well.

I wonder just how far reaching we can be. Sure, one day our sun's going to go supernova or Earth will implode due to global warming, but hopefully by that time we'll have figured out other places to live. Plus, once we figure out how to inhabit other planets, issues like global warming or the environment will pretty much disappear since there's always more planets (and someday, more universes).

[Alleya]

This universe being contained within a black hole doesn't make much sense to me, since the universe is expanding. Kind of the opposite of what black holes do. I think it's more likely that our universe was born out of a super massive giant huge colossal black hole that formed after the collapse of a previous universe, became unstable, and exploded again. Though now most predictions show the universe continuing to expand forever.

I'm more interested in the boundaries of the universe. Is it something infinite, and the "expansion" is just risidual energy from the big bang or something finite that will eventually have some kind of effect on the movement of matter? I think that's what makes containment theories intriguing and popular, it's much easier to imagine something with theoretical limits than something infinite, even if it's thousands of googol light years in diameter.

We could compare someone flying inside a black hole to someone who is flying at the speed of light I think. If you are going at 300 000km/s, time is going to stop for you and everything outside will happen at the same time. That would be the equivalent of t = 0 when you are on the border (time progress is slowing down until it freeze completely). That would be why the big bang is instant, since everything happen at the same time.

In a way you will always appears at the beginning of the new universe no matter when you entered inside the black hole. If you manage to affect the blackhole from the outside (tidal force), you would affect every time period at the same time.

After the initial t=0 bigbang, it's easy to imagine time slowing down the same way it did for universe.

[Fhqwghads]

Our sun will never supernova, btw. Not enough mass.

As far as the expanding universe, maybe that's the opposite and equal reaction of some super-super-massive black hole in another universe. In that universe, the black hole is consuming matter, and in this universe, it's expelling it. The expansion and acceleration of our universe could be the result of unfathomable amounts of material being consumed in the other universe and explled into ours.

Couldn't it also be the displacement of current material?
IE Black Hole at Point A 500 Billion Light Years away is putting matter out at Point B 250 Billion Light Years away and Point B is closer to us in proximity and thus the displacement of the material makes it seem like its coming from another universe?

I dont want to start the whole debate again, but most scientist agree this step is too huge, and we will most likely never be able to accomplish such feat. Exploring other planets is physically possible, but there is large technical constraint. First problem is light speed and time it take to travel from one star to another. Closest star is 5 lightyears away from us, so expect traveling 100 years to reach it (and sadly, it's not likely this one has anything interesting for us. To compare, moon is about 100millions (7seconds/5years) time closer than the closest star...so the step isn't little.
To this problem is added material problem. No matter what you mix tungstene in 1 millenium, it wont make a magical alloy. Matter has limit, and it will never be able to resist extreme force.

Leaving our universe require force that are infinite, division by zero and negative square root,so it's even less likely considering the mathematical constraint that bind matter to this universe.

I think your view of space/time is too static when you put it that way. It's possible to have an infinity within a finite space, that's basically what a black hole are.

Earth won't implode due to global warming, either.

Although, isn't the total amount of energy/matter in the universe constant? If matter enters a black hole into another universe, wouldn't that subtract energy/matter from ours and add it to the other? Unless that sub-universe counts as a part of ours, and so the total across both are still constant. In which case, eventually, our entire universe would be sucked into a black hole.

Isn't there some geometric shape or fractal that has an infinite perimeter but finite area?

Still going to get big enough to roast us tho ;/

I know that articles made it sound that way, but I doubt it works like this. I can't see how 2 black hole would connect each other randomly considering their creation is an unique event completely unrelated with the creation of another black hole.
Maybe I missed something important, but there is something illogical with that theory proposed in the article.

Black hole =/= portal. The black hole itself, even if it's an universe on its own (or not) is still considered as a physical object with a mass and normal gravity that can be calculated with Newton's physics. If the sun would become a tiny blackhole, the Earth would continue to rotate around it like nothing happen. So yes, those sub universes would always count as part of our. They could possibly be destroyed and matter would be recuperated by our universe.


A scary thought is that our universe expansion might be caused by the destruction of the blackhole in the "above" universe.

Armchair science! Armchair philosophy would be if we started talking about the meaning of life and what our place in the universe is.
