Yes. You cannot bend the fabric of the universe.

You didn't say at all how;
mathematical models not exactly lining up with the physical world = fabric of space time is unbendable. I see what you're trying to say, but we're talking relative to the observer, not in the grand scope of the shape of space. We can't really bend it because we're in it, but you know what I'm fucking referring to. Can we initiate an action that bends space time? Yes we can

>>8421139
>You cannot bend the fabric of the universe.
Umm... You cannot, not, bend the fabric of the universe - basic relativity. It bends all the fucking time.

>>8421033
But yes, it is. While they may theoretically exists (and in fact, probably do, given that all the other predictions have been solid so far), traveling through one would be a lot like traveling through a black hole - you become spaghetti then and are eventually reduced to elementary particles.

You might be able to send information through one though.

Creating one involves some non-FTL travel between the two points, so there's limited usefulness in that.

No, the mathematical models says that space bends, and the experimental and observational evidence says that space bends. Which is why we see shit like this, and why your GPS works.

Whether *we* can artificially bend it (beyond sticking a lot of heavy stuff in one spot) that's another thing, but naturally occurring bent space is everywhere.

in relation to pic above,

basic topology prohibits it.

in order to make space time overlap (which may be impossible) you first have to rip it apart (which is also likely impossible)

wormholes could exist from a topological point of view, but not as described in pic above.

I watched that movie again recently and there are a lot of unresolved plot threads

for example they use the scanner to detect lifeforms across the ship but I don't think they even explain wtf that means. Was it supposed to be ghosts? Can the machine detect ghosts? Are they ghost busters?

>>8421754
*The scanner detects thousands (more?) lifeforms on the ship.

>>8421757
Haven't seen that movie in years, but maybe it meant the ship itself was alive, and possibly just as insane as everyone else who came back. Unable to mutilate or kill itself it utilized the rescue crew for that task. That puts a whole new spin on things. I think I need to watch it again.

>You cannot bend the fabric of the universe.

You can't into gravity. The currently accepted, most complete theory of gravity the human race has, is built on the premise that it is directly due to mass bending and curving spacetime.
By the way, the recent detection of gravitational waves from the merger of two black holes, is concrete proof that spacetime is constantly warped and bent by mass/energy.

>>8421442
Do you know anything about general relativity? Learning it now in uni. Black holes were predicted as a result of certain boundary conditions in the Einstein field equations. We have recently (empirically) detected the merger of two black holes into one larger one, and the subsequent emission pattern of gravitational waves (also a prediction of the field equations).
Really anon, I have the paper sitting in front of me right now.

Given that the rest of the universe burns out, and the large black holes absorb all the remaining matter that hasn't been put beyond their reach by the accelerating expansion of the universe, magnitudes of trillions of years before they evaporate, yes.

But the sun will probably expand to fry us before we run into one, and the biosphere rendered useless for life well before even that, so meh. Bobby McFerrin had it right.

The idea is that there are two or more black holes bending space in such a way between them as to create a funnel.

>>8424437
GPS works by satellites and timing. Since the geostationary satellites in question are in a higher orbit, they are under less gravity, and, relative to us, time slightly moves faster for them. Einstein's relativity calculations are applied to compensate for this, as otherwise, within a week or two, the GPS information would be off by a few thousand miles.

Poorely formulated but yes, in GR the gravity doesn't change a manifold, it changes its metric tensor. Which is perfectly sane. With wormholes you have to change the whole topology of a manifold.

Micro black holes aren't a threat - if they already had strong vectors, they'd pass through the Earth with little to no effect. If they did get caught in the gravity well, they'd oscillate in the middle, but wouldn't gather much matter.

The reason for that is micro black holes put off a shitton of Hawking radiation. So, as a certain heavily accented speculator once said, getting matter into them is kind of akin to getting a beach ball into a fire hose, that's turned on.

If they passed close enough to you, rather than sucking you into a timeless vortex, they'd fry you with radiation.

Also the article is neglecting the fact that atomic sized black holes don't actually last very long. Any created at the dawn of time would have long since evaporated. However, they may still be common, as they can theoretically be created by other means.

>>8426591
Yeah... True it's interesting, and maybe not entirely without purpose, but until you can find a way to test it... I mean, like string theory, you can make up perfectly functional mathematical models explaining why everything is as it is, but with no way to test them, it's just really elaborate mental masturbation. Math isn't reality, it's only a language, and can describe all sorts of perfectly logical things and interactions that are, nonetheless, not real and not happening.

Though there is also the matter of doing the work to see if it creates more problems than it solves. (Like say, Electric Universe theory did, well before Rosetta crushed it for good.) A lot of these explanations don't even pass that test.

More to the point, it operates on such a small scale you can't test for their existence, not even indirectly.

If we one day build a particle collider the size of the orbit of Mars, maybe we'll finally kill it once and for all, but until then, you can say almost anything you want when working in that realm.

Well, if you're worried that you might get struck by lightning, win the lottery, and be stuck by a meteorite, all at the same time, then you might have to worry about a micro-blackhole passing close enough and slowly enough to fry you as well.

But, even then, at least you still don't have to worry about getting sucked into one, as they don't work that way.

White hole is something that emits matter/energy because someone thought that black holes has to have opposite.
But now we know that black holes are "white holes" as well because of hawking radiation. They even can emit visible light.
Things that fall into black hole doesn't disappear or get moved to somewhere else. They all are become energy and are slowly returned back to universe as radiation as black hole "evaporates".

>>8427127
That's... Not actually what a white hole is supposed to be, or what the theory was about. But as they probably don't exist, meh.

No, a wormhole is two black holes that connect "at the bottom". You could survive jumping into a black hole IF it was large enough, but you die when you hit the singularity regardless of if it's the singularity in the hole you jumped into, or the one that's connected via the wormhole. There's no way back out of the hole at either end so it can't be used for travel or communication or really anything useful.

>>8428583

Shuttling degenerate matter? Or is it just some sort of weird distortion in space and time?

That's a Schwarzschild wormhole, Schwarzschild wormholes are not traversable wormholes (lest you go all Kip Thorne on them), and thus not what we're talking about.

We're talking about Ellis drainholes, those related Raychaudhuri's theorem, or the flux pinhole wormholes.

The funnel can be created by an interaction between black holes, other heavy objects, and/or dark matter, but it doesn't necessarily have to lead to any one of them, in much the way a series of large objects floating in a pool can make a whirlpool between them, the center of which does not connect them. (And in some variants, the objects that created the wormhole no longer need to be there, or the hole maybe the result of a cosmic string in the primordial universe.)

You still suffer the spaghettification effect as a result of the forces involved, but, in most of those models, as the forces are twisting in a specific rotation and exiting in open space, thus nothing gets trapped inside a singularity as a result of passage.

>>8428605
Black holes have all sorts of potential uses...

Provided you can build thousand mile wide orbital solar arrays to power super-accurate lasers to create them on the trajectory you want them...

https://www.youtube.com/watch?v=x32AkL6HPfc

Traversable wormholes are only good for communication though, and if they can be setup artificially, it'd require you to make the journey at sublight first, setting a whole series of blackholes up along the way.

>>8428605

Yes they are indeed interesting. I believe they play a major role in our universe as ultra obsessive interstellar psychopaths devouring everything in its wake...creating massive amounts of destruction in its wake until everything is consumed; Leaving itself the sole survivor until the next encounter.
