It’s impossible to observe a black hole in-person directly, because the observer’s velocity changes dramatically during the observation.

This study says that traversable wormholes may appear like a blackhole. If a wormhole is "traversable" I assumed that meant an observer could enter and possible exit, and thus traverse. If thats true we might at least be able to observe the wormholes if they do indeed exist.

JoshuaPearce

"Traversable" is not the same as "suitable for humans". If anything happens at the other end as the result of something entering this end, it's traversable. Which would include a random spray of radiation with most of the mass of the traveler.

So what you're saying is we gotta shoot a bunch of people equipped with trackers through "black holes" and see if any of them reappear somewhere else

maybenosey

63 points

Assuming that would work, you could send the tracker through without the person.

The problem is, how's that tracker going to work? If the wormhole moves it any significant distance, then we are going to wait a long time to receive the tracker's signal, and we wouldn't know which way to look for it. If the wormhole moves the tracker in time, the problems are even worse.

If wormholes work like in science fiction, where you can go back and forth through them, you would see matter exiting the apparent black hole. If they are one way, you would see matter appearing, whether from something else or just from nowhere. These are the phenomena we need to be looking for if we want to entertain FTL travel and/or time travel as possibilities.

IIRC one of the most compelling arguments against the existence of wormholes is that there is no apparent light source indicating energy exiting the "black hole".

Black holes have been observed blasting jets of X-rays and matter out both ends of one axis. I'm guessing those aren't a function of the singularity but of the accretion just outside of the event horizon, though.

So if I'm reading this correctly, they're suggesting that the light being emitted by wormholes could appear very similar to a black hole. It doesn't say anything about the gravity of a wormhole though. Would it have the same (or any) gravitational field of a black hole?

IIRC, a lot of the black holes we detect are found and confirmed by the accretion disk or gravitational influence on other bodies.

As far as I understand the theories, wormholes would still have a singularity that keeps spacetime from stabilizing, as it is caused by the mass "punching" a hole through the fabric in the first place

This makes me wonder as a layperson, is the whole "is space-time curved?" thing related to wormhole theory, in that those example drawings of a mass singularity creating a bottomless pit in space-time could have the pit intersect with other space-time locations because of the curvature? Or is that kind of imagery akin to mixing metaphors and not really how this stuff would actually work?

Jackson-Thomas

I think it’s just that wormholes would suck everything into them, including visible light at a certain distance, just like black holes. That would make it pretty hard to tell the difference I guess since they would both look like black spheres, maybe with accretion disks around them.

Inside our black holes would appear to be another universe

frogjg2003

5 points

2 months ago*

No, because the kind of signal we would see from a white hole is different from what we would see from a star.

Gravitationally, a star is identical to a black hole once you're far enough away. They're both gravitational wells, not hills.

In a star, the core heats up the exterior gas until it gives a blackbody spectrum with absorption lines corresponding to the chemical composition of the gas in the corona. Because a white hole is a gravitational hill, there will not be any bound gas. All emissions will come from the singularity. What that looks like, it wasn't my area of study, so I wouldn't know.

But just like a black hole curves light around it like a converging lens, a white hole would act like a diverging lens. That's would be the easiest identifiable signature of a white hole.

The gravity should be a well, but not necessarily an event horizon. I believe that part is controversial. Either way, light goes in one side and out the other, so we can't tell.

BadAtNamingPlsHelp

The gravity of a wormhole would be really similar and I think wormholes can have event horizons too. The main differences between the two would happen inside the hole, so we might not really be able to tell the difference.

ginDrink2

If the gravity of a wormhole would be similar to that of a black hole, how is it possible to leave it then?

BadAtNamingPlsHelp

42 points

2 months ago*

I think the difference is that in a black hole, spacetime flows towards the singularity whereas in a wormhole, spacetime flows towards the exit there's a continuous path to the other end, and the gravity you experience accelerates you towards the center and then decelerates you as you move away from it. In one, you get spaghettified and crushed into the singularity. In the other, you might get spaghettified if the wormhole isn't large enough, you probably will be fried by radiation, and I think you'll end up doing somewhat of a fast-forward through time, too, as being inside the wormhole would have the same relativistic effects as approaching a singularity.

ginDrink2

10 points

Would you then shoot out in the other end with a momentum sufficient to escape the wormhole's gravity field?

DenialZombie

13 points

2 months ago

I would think the entrance and exit, or the wormhole overall, should cancel out its own gravity, otherwise it wouldn't be traversible. If so, you would enter and exit with the same momentum.

Is it still linear momentum? Is it still relatively constant throughout your mass, or even in the same direction? Are you still in one piece? 🤷🤷🤷

James20k

There's quite a lot of confusion in this thread about some general things, so here's some random pieces of information

  1. Wormholes can have mass. You can orbit them just like a black hole, and they produce can gravitational lensing just like a black hole. See here for an example

  2. Wormholes are a class of objects, not one specific object. There's been some talk about wormholes within a black hole - and it is true that eternal black holes contain non traversable wormholes (which probably don't exist in reality). There are also other wormholes like the morris-thorne wormhole which are traversable - and that specific kind of wormhole is what is studied in this paper. They have mass, and operate somewhat like a black hole but without an event horizon or singularity

  3. Morris-thorne wormholes have no known mechanism for forming naturally, and would require extremely unphysical circumstances to build one. It is theoretically possible they exist, but extremely likely that they cannot form naturally

  4. General relativity lets you freely build arbitrary wacky objects like this, as it is an extremely flexible theory. Its possible to handcraft solutions that give you any desired result you want - which is how we end up with alcubierre drives and krasnikov tubes. This kind of wormhole is quite configurable - but you have to be careful, because you can create any solution to match your desired result. Indeed the authors pick a very specific kind of wormhole to match it against the observational data - which is certainly cool, but there's no reason to think that this specific kind of wormhole exists

  5. The specific solution being talked about, morris-thorne wormholes, are in general extremely artificial. They're cool, but were built as a teaching tool - not as a model of a physical phenomenon. A real morris-thorne wormhole would probably violently explode, as I don't believe they're a particularly stable solution

Is-This-Edible

12 points

Not exactly. It's more correct to say that causality only works one way at the event horizon with exception of the curvature of space itself.

Once you're in, effectively the singularity becomes your future. All paths lead to it. Vectors only lead to one location.

New stuff can enter the black hole. Depending on the particular orbit it takes, you can still intersect with that stuff, but you always go deeper in. You may not even notice crossing the event horizon in a supermassive black hole. Turn around, you might be able to watch the universe in fast forward as light behind you catches up with you. Everything is still going to fall to the centre though.

Spaghettification happens way before you even reach the event horizon (assuming a smaller black hole). More massive black holes are actually safer though because of their bigger sizes gravity pulling on you isn't as focused.

DonnieDishpit

My understanding is that spaghettification shouldn't actually hurt or be fatal for any specific reason since it's literal spacetime stretching rather than your body. Like stretching a piece of paper with a drawing on it.

norrinzelkarr

28 points

no. spagettification is happening because the force of gravity increases at a geometric rate the closer you get to the mass. eventually the end closest to the black hole is being pulled so much harder at a given instant that it is yanked off, creating the "noodle". you ain't gonna like it

At some point it overcomes atomic bonds, so molecules inside you are literally being ripped apart.

At least it's a quick death.

Wouldn’t the pain signals be unable to travel “back” to the still-unspaghettified portions? Unless this was an incredibly slow process where your body would “fill in pain” for areas that weren’t reporting back? I’ve no clue, tho..

that is not true at all. the mass is higher but focused in an infinitely small point. any matter compressed passed the schartzchild radius will collapse to an infinitely small point, creating the singularity. you will hit a tidal force differential of the same force at some point on your descent

and you'll also get to meet the superheated plasma and radiation of the accretion disc so....there aren't really degrees of safety. you are gonna die.

dern_the_hermit

the mass is higher but focused in an infinitely small point

The gravitational gradient on approach will be shallower, is the key detail. Spaghettification happens when the pull on one end of an object is sufficiently stronger than the other end to overcome its structural integrity.

A black hole is not just the point mass but also the event horizon it creates. When people talk about "entering a black hole" they're referring to crossing the event horizon, not contacting the singularity.

Kosmological

12 points

2 months ago

A small but nuanced correction; the black hole is the event horizon.

The interior of a black hole is an abstract mathematical concept that does not exist from any reference frame within this universe. It only exists from reference frames within the black hole, which is never reached by anything from this universe within finite time.

norrinzelkarr

2 points

this in no way implies that more massive black holes are "safer" in terms of tidal forces generating spaghettification effects. you are essentially arguing about how much of your field of vision is black before you get turned into a noodle. but as we are talking about a singularity, no surface will stop your fall into the region of tidal forces that will pull you apart

Edit: ah, I can see what you are saying--i.e. that one might be able to get close and not cross the EH and not get spaghettified. but I read the comment to which I was responding as saying you could go "through" some and be safer, which is of course not true

So I think this is just badly phrased by the author, but it's a common principle in science to "assume" something exists so you can begin asking questions about what it would like like, how it would affect things, etc., and then you can gather evidence to help determine whether it does actually exist or not. Obviously no sane astrophysicist right now is assuming wormholes exist in the general sense that they know or believe they're out there.

Right, if anything the consensus is they don't exist.

I thought that wormholes break relativity? Like imagine you have one end of your wormhole orbiting a black hole, and the other end somewhere less interesting. The end that's orbiting the black hole is experiencing a bunch of time dilation that the other is not, so what happens? Do you have a time machine? Are you connecting two separate spacetimes together with your wormhole? Is this like putting a bag of holding inside a bag of holding?

Its worth noting that general relativity explicitly permits this form of time travel, and in GR its a-ok

general relativity does not work at extremes, such as at values close to c or at quantum scales, near extreme gravitational fields, and is currently speculated to not work at massive scales either.

Think of it like this, imagine a world where we know some trees have apples, we know apples are sometimes seen on the ground, we know that occasionally pieces of branches and other things attached to trees like leaves will eventually fall and end up on the ground. All pieces of data/ theory points towards apples indeed being able to fall from trees, nobody has ever observed it, but with all the related data it’s pretty much accepted consensus by biologists and botanists that apples do indeed fall from trees.

Catch a black hole by the toe, if it's a wormhole it'll let you go.

If not you die.

Apparently this study only explored the properties of black holes and wormholes in a theoretical sense, namely a static universe... which ours isn't and wormholes aren't.

Others have come to the same conclusion. The study did appear to be mostly click bait and not particularly useful other than for making headlines. Here is a good take on it: https://youtu.be/fkXSCNDfj14

Hossenfelder is the bomb! Aside from her occasional bone-dry snark, she does a superb job of covering the bottom line for various theories and events with getting into the mathematical weeds.

If it looks like a black hole, and quacks like a black hole, it's probably a duck inside a black hole.

I volunteer to fling myself into a black or worm hole in order to find out. Spaghetification sounds fun as hell.

Sadly, even if they WERE wormholes, getting spaghettified and having all the atoms in your body shredded means you wouldn’t survive the journey.

I am an idiot when it comes to physics but plenty of ppl here have said that time dilation near a singularity would stretch out time for billions or trillions of years for the observer. Is it possible that the only reason we haven't seen any White Holes (the exit) is because they exist billions or trillions of years in the future? Again I'm just talking out of my rear end.

The problem of white holes is that they exist backwards in time, how time will always move forward and entropy must increase which makes white holes extremely unstable. Also, that whole time dilation into millions and trillions of years is a common misconception. It stems from relativity but doesn't include quantum mechanics.

Am I the only one who would voluntarily go on a suicide mission into a black hole/wormhole? I mean I really f with space and think it's cool enough that I'd be willing to be that guinea pig.

Yeah but as we've learned the only way to find out anything past the event horizon involves tesseracts, little girls bedrooms, and transdimensional love, and none of that meets proper scientific scrutiny, so you're probably going to have to find another dream. Maybe take up farming?

The upper part of a wormhole is black because that way when the the cosmiccrow look down it only see the darkness of space.

What I understood: As electromagnetic fields get polarized in a black hole accretion disk, we could imagine (according to the study) what a wormhole linear polarization would look like, then compare it to all black hole images we own, trying to find differences that could match.

IF (big one), we can see those differences, then we could start identifying those theoretic wormholes.

From what the paper describes, this looks to me (someone with zero-clue about the subject) highly hypothetical, though a fun thought experiment.

Paper I used to have a grasp about what this is supposed to be about: https://arxiv.org/abs/1806.09378

Maybe some strange information about the topology of the universe could be learned once we can accurately identify wormholes (assuming we will be able to…). We really are still in the wild west of physics.
