There is a question I've always wondered about. Could black holes be a gateway to other worlds?

The problem with black holes is all of our theories about how physics work start to fall apart. Or we just don't know how to make sense out of the math.

There is very little evidence pertaining to what is on the other side but based off what we know right now it is more likely that a black hole essentially punches through a piece of the fabric of reality itself. What in science is called space-time. Nobody knows what's on the other side, if there's another side or what it might be like there.

It seems there's enough room for speculation that there could be other realities beyond them, but unfortunately even as an idea, it's impossible for anything going in to come out in one piece

[strateguy632]

i don't know which website fed you that stuff, but real science knows black holes are mass so stuff falls in.

[Telekinetic-Potato]

@strateguy632 Well, it's pretty complicated for someone who only knows the basics but I'll try.

I guess the first thing is understanding the concept of a singularity, NASA has a pretty great explanation.
science.nasa.gov/universe/black-holes/anatomy/

They doing go much deeper into it because of the war on string theory that's happening in the science community right now. (if you've ever heard that there's 10+ dimensions, they're probably referring to string theory)

The big issue with black holes and singularities is that they make no sense. Nothing should be able to be infinitely dense over an infinitely small space.

[Telekinetic-Potato]

Adding to the mystery, black holes don't release radiation proportional to what is entering them.

The NASA link refers to particle jets, which are commonly misunderstood to be coming from the black hole itself, but this is not the case. There are certain types of radiation coming from the black hole, but again, not even close to what is expected.

So the question is, if matter cannot be created or destroyed, where is all this matter going?

Many scientists who have theorized about wormholes, the shape of our reality we live in (which is largely a string theory thing), and other bizarre possible phenomena have their guesses and within the confines of what these people have mathematically worked out and been able to test. Which isn't very much at all, it is believed that it is mathematically plausible there could be realities which are largely separate and outside the confines of our own.

So far as the fabric of spacetime goes a basic course would be about how gravity and spacetime bend according to general relativity. There are plenty of videos on YouTube so I'll just pick one.

Neil isn't my favorite guy but he gives a very concise overview of how wormholes work which plays into some of what is required to understand this concept. Plenty of articles/ videos you can look at to cover everything he talks about here in depth.

[Telekinetic-Potato]

Here is a interesting paper discussing the chararistics which shape a wormhole and alludes to them collapsing into black holes under certain circumstances.

www.researchgate.net/.../276243607_Wormhole_Dynamics

The shape of reality thing is controversial and takes on many forms. This article does a good job at glossing over this topic on a surface level kind of way.

As for other universes, here's a video covering a research paper on this topic. Obviously there are others of varying levels of credibility but it's an interesting conversation that helps shape what were talking about.

Some might be, but you would never survive the trip without being shielded by a really large amount of negative mass, which itself probably doesn't even exist.

Assuming you did somehow manage to get enough negative mass to make the trip, it's one-way only so you would be forever lost to the universe you came from so you had best get your affairs in order first.

Finally, you don't know what kind of reality is awaiting you on the other side: it could be like ours, be an endless empty void, or a chaotic hellscape with different laws of physics like the warp from 40k. Your odds of ending up on a parallel Earth, or even something resembling habitable are beyond astronomical.

TL;DR even if you succeed you will probably die, and nobody you care about will ever see you again.

[Jessica405]

Better terminology would be blak sphere. As far as we know, they are spherical in shape. Like a massive dead star that sucks in matter and possibly time as well. Its mass and its gravitational pull steadily increase. As an object approaches, the leading edge or surface is pulled harder than the rest, so it would be stretched , but would eventually flatten as it forms a new surface of the black sphere.

The only gateways that might exist are "worm holes".

[Sarah2007]

Consider it the same as a big whirlpool eccept 10000x bigger, things fade inside it and get destroyed / die.

There is no such a thing as another dimension / other worlds.

This is the issue with todays world as people watch a lot of movies and think it's what actually happening in real life.

Reading and educating is very important when it comes to such things.

[FunkyMonkee]

How do you know there's no such thing as other dimensions? We know of at least 13.

[Sarah2007]

@FunkyMonkee as an old person, you should understand such things rather than questioning it like my 8 y/o brother lol

Other dimensions don't exist, we are not in a movie, but ofc the solar system is wide and full of hidden secrets which no one discovered yet ( still no other dimensions )

[FunkyMonkee]

As a young person, who would you know there's nothing else out there? Comic books? Star Trek TNG? Stargate?

[ClaircognizantEmpath]

hey, my instincts have always been like a portal.. they taught it sucked things in that never got out... well now things have come back out... energy force has been detected coming out of it... like a charge or a purge? who knows... i imagined them up there like an invisible pac man just munching its way around.. and when you step through one it pops you out into another universe with a billion galaxies... I've also thought its like our universe could of exploded out of one, as in birthed into existence.. maybe when ours collapses the energy will escape through a black hole because energy cannot not be..

[normalice]

Worlds? No. Universes, maybe, but it's unlikely. While we don't really know what goes on in a black hole, we know how they are made. And there are no ingredients that would populate a parallel universe or something. Indeed, the energy that continuously holds it together is evidence that that energy is remaining in this universe. Moreover, when we say we don't know what goes on in a black hole what we really mean is we don't have equations for when the progression of time is halted. We do know the core of a black hole is just a lot of iron.

[Cice137]

An interesting and thought provoking book that goes into the physics behind some of this stuff that I really like is called 'Causality, Electromagnetic induction, and gravitation' by Dr. Oleg D. Jefimenko. FYI its VERY math and physics intensive.

[jshm2]

No.

At best, black holes are the ultra "dumping grounds" for matter in the universe. Sort of like where all the universes garbage gets chucked into to get "compressed".

But it all comes down to dark matter's role in all of this. Once we know that, we can know what black and white holes really are.

[purplepoppy]

No they just crush you. I invented black holes to deal with the problem of an ever expanding universe that risked tearing itself apart. Black holes act as buttons that pull it together and keeping everything in balance.

[Lynx122]

Thank you master of the universe for looking out for us :)

[worldscolide]

Its entirely possible. Supposedly Black Holes are supposed to have a counterpart called a "White Hole" But its all theoretical because no one can ever get close enough to test said theories. They are also the most dangerous things in the universe. At the heart of every galaxy resides a super massive black hole. In the case of the Milky Way, There are several super massive black holes in its core.

[RebelinSteel]

Probably not, however no one really knows. The fact they are extreme gravitational zones points to them not being useable. However technology over next thousand years might change that. It’s 1.6 trillion g's that we have on earth.

[FunkyMonkee]

Maybe somebody else already has the tech to use them as transportation portals.

[RebelinSteel]

@FunkyMonkee maybe, however it’s the 1.6 trillion g's that anyone needs to overcome. For example you could not use laser comms or any system using fibre optics.

[FunkyMonkee]

In the meantime, aliens have the tech to go at least light speed and turn instantly without the the incredibly massive G's effecting them in the process.

[RebelinSteel]

@FunkyMonkee they need to go beyond light speed, which then causes issues with having crew if at that speed. De acceleration is a major thing. If we do have Aliens ever visit, they will walk over is in a few hours.

[FunkyMonkee]

They've BEEN coming here for millennia! If they WANTED to destroy us, they have the tech to do it so, what's been keeping them FROM doing it?

[RebelinSteel]

@FunkyMonkee no they have not, that’s the worst crap in the world 🤣🤣🤣🤣🤣🤣

[FunkyMonkee]

Yeah, they have! We're proof of that! They created us! We're their science experiment and this planet is their laboratory.

[RebelinSteel]

@FunkyMonkee yeah sure 🤣🤣🤣🤣

[IslaTheWitch]

in theory, they can

but we wouldn't survive this gravity... so what's the difference?

[Icaine702]

There is a scientific theory that black holes do lead somewhere, and they exit out something they call white holes. Now wheather that’s to another universe, dimension, time and space, or what have you is what we do not know, or if the trip through would be survivable. The general consensus is they would just crush you but that is just a theory as well because we haven’t sent anyone or anything through yet.

[Static_In_The_Attic]

Gateways could be where we least expect it & as for a gateway to other worlds within a black hole it’s certainly possible & worth exploring if we have the right technology.

[NamerOfStars]

No, unless you count the afterlife. Despite the name, they're not actually holes; they're more like balls.

[jahaims]

In theory you can connect two black holes to make a wormhole to travel spacetime. You use them to bend spacetime to cut down travel time. We have no way of manipulating them in a useful way with current technology.

[strateguy632]

but if you get close you can never get away on same side or even if imagine the other second one.

[WhitneySnow]

Probably. Or they might just destroy everything that falls inside them

[DannyUk2017]

We will never know! unless one of us makes it Above the Firmament.

[strateguy632]

they can't be, you are thinking of the bridge called wormhole but black differed.

[Staximus]

We know approximately jack shit about black holes, but it's reasonable to assume that if stuff goes into a black hole then it must come out or go somewhere, and who knows where that is.

[ChicoFromThe305]

I don't know but I'd jump into a black hole for science

[pethouse]

Everything we know about black holes are based of theories.

[Yannae]

A gamble too risky and costly to take.

[abc3643]

Probably not.
