Feeling like taking a vacation.
same as you would anybody’s hole: just pull out.
How would one exit a black hole?

You don’t.

That’s the fun part, you don’t.
fritobugger2017@lemmy.world 7 months ago
I don’t know about exiting but I like Enter A Black Hole Backwards followed by Chilly Water.

With space time snapshot machine I guess, you setup space time snapshot machine to take snapshot and setup detector on your body particles to roll you back from snapshot after your every particle is altered and it rolls you back to previous state. I think this should work.

And never trust it when it says “quick save” always make a manual backup!
RizzRustbolt@lemmy.world 7 months ago
Find the Myotrope, invert your orthocameral orbit, grab your ankles, and hold on!

You’ll be slowly radiated out one half of an entangled pair of particles at a time. Arranging for reconstruction might prove difficult.
AA5B@lemmy.world 7 months ago
As a jet of energy, assuming you haven’t actually crossed the event horizon
wreckedcarzz@lemmy.world 7 months ago
You go into a white hole, duh
jerkface@lemmy.ca 7 months ago
The only direction is forward.
RickyRigatoni@retrolemmy.com 7 months ago
You just pop out the white hole on the other end.
BrainInABox@lemmy.ml 7 months ago
One wouldn’t
PetteriSkaffari@lemmy.world 7 months ago
You can eveporate your way out of it, given enough time.
Strider@lemmy.world 7 months ago
Through a white hole.

since black holes are incredibly common in the universe, if everything that went into a black hole came out the “other end” from a white hole, then it would logically follow that white holes would also be incredibly common. however, while white holes might exist, nobody has ever observed one, or found any mechanism capable of creating one, or evidence suggesting that they even exist, or have ever existed, or will ever exist. meanwhile, we have directly imaged the accretion disk around a supermassive black hole.
one definitely exists, the other is firmly within the realm of theoretical only, where it is expected to stay indefinitely.
Olhonestjim@lemmy.world 7 months ago
Or if every Universe begins with a white hole, you now have a set of keys to the Multiverse.
phoenixz@lemmy.ca 7 months ago
Space time gets so curved that literally every direction around you is the center of the black hole.
You look forward? Black hole center.
Behind you? Center
Up down? You guessed it
From your perspective, the center literally is the only direction you can go, deeper.
SkyezOpen@lemmy.world 7 months ago
So if you walk backwards, every direction leads out. Easy!
phoenixz@lemmy.ca 7 months ago
So if you walk backwards, every direction leads further in. Easy!
Exactly!
renamon_silver@lemmy.wtf 7 months ago
Vacation is seeming further and further away.
ilinamorato@lemmy.world 7 months ago
Well, the end of it is, at least.
phoenixz@lemmy.ca 7 months ago
The good news though is that so does work. So does anything, really.

Spaghettified… Mostly.
DeathByBigSad@sh.itjust.works 7 months ago
Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
dogs0n@sh.itjust.works 7 months ago
When you’re ready, you should see a bookshelf. Start messing with the books to send a message to your daughter and maybe she will help you.
Prerequisites: daughter

don’t fight against gravity by trying to fly directly towards the universe. Instead, fly parallel to the universe until you are out of the black hole’s pull, then angle back towards the universe.
Backhandedsmack@lemmy.world 7 months ago
No no no. You need to take the u-turn at the other end of the universe.
xePBMg9@lemmynsfw.com 7 months ago
With the assumption that we are alright in there, wait until it evaporates naturally. I hope you brought a lot of books, cause depending on its mass, it can take some time.
ilinamorato@lemmy.world 7 months ago
Actually, it may be that it quite literally can’t take any time inside a singularity! As you approach a singularity, the spacetime curve representing the passage of time approaches zero, meaning that from your perspective, the universe outside the event horizon moves more and more impossibly fast, and from an outside perspective, you move more and more slowly until your motion appears to stop entirely.
At the singularity, our understanding of spacetime basically just shrugs in an infinite manner, puts on its hat, and clocks out for the day. It may be that, for the singularity, the entirety of time between the collapse of the star that formed the black hole and the eventual evaporation of the black hole due to Hawking radiation are compressed into a single instant, and no time at all passes for it.
So you might not need any books at all, because by the time you reach the singularity (which wouldn’t take a particularly long subjective time), it may well be the end of the universe. Hope you paid the meter.
RedGreenBlue@lemmy.zip 7 months ago
Enjoyable read!
667@lemmy.radio 7 months ago
Only from an outside perspective. Inside the black hole it’s already next Tuesday.
BeatTakeshi@lemmy.world 7 months ago
You just need water and magnets
BeatTakeshi@lemmy.world 7 months ago
You throw a big party in a place as far as your eyes can see. You call it the event horizon.
Kolanaki@pawb.social 7 months ago
Generally speaking, as Hawking Radiation.
HeyThisIsntTheYMCA@lemmy.world 7 months ago
what if i want to use my legs afters
adespoton@lemmy.ca 7 months ago
You’d have to build them first.
Anything more complex than an atom is going to be disintegrated before it even enters a black hole due to the intense energies at play at the interface.
zakobjoa@lemmy.world 7 months ago

Tiger666@lemmy.ca 7 months ago
The singularity will pull you in, feet first, then the tidal effect will spaghettify you. You will be ripped apart atom by atom by those same tidal forces. You cannot escape the event horizon.
Good luck!
CatDogL0ver@lemmy.world 7 months ago
Perhaps op can escape in a form of radioadiation…
thatradomguy@lemmy.world 7 months ago
feed it taco bell
Im28xwa@lemdro.id 7 months ago
go to the other end
Notyou@sopuli.xyz 7 months ago
Exactly, when you’re going through hell, keep going. Maybe you’ll find a white hole in the other end with a new universe to explore.
allo@sh.itjust.works 7 months ago
with a stronger blackhole next to your blackhole. just have a stronger pull.
its like how do u have bribed politicians not vote according to that bribe: bribe them with a bigger bribe.
JPSound@lemmy.world 7 months ago
Literally, impossible. To exit the event horizon of a black hole, you’d have to travel faster than the speed of light. We know for a fact that anything with mass cannot travel at the speed of light. (And anything without mass MUST travel at the speed of light) Once you cross the event horizon, you’ve been entirely and irreversibly separated from the rest of the universe.
aeternum@lemmy.blahaj.zone 7 months ago
And anything without mass MUST travel at the speed of light
You’re not the boss of me! I do what i want!
WoodScientist@sh.itjust.works 7 months ago
It’s not even about needing to exceed the speed of light. Once you cross the event horizon, spacetime around you is so warped that “out” doesn’t exist anymore. Point your ship in any direction and fire up your FTL engine; it doesn’t matter. No matter which way you try and fly your ship, you’ll be getting closer to the center. Once you cross the event horizon, there is literally no way out.
JPSound@lemmy.world 7 months ago
I love how mind bending it is imagining what lies inside a black hole. Everything we know about physics essentially goes right out the window beyond the event horizon.
chicken@lemmy.dbzer0.com 7 months ago
Does this also mean that black holes are totally indestructible?
JPSound@lemmy.world 7 months ago
Well, there’s the hypothesis of a “naked singularity” whereas if enough charge or spin could be added to a black hole, the event horizon, aka, the black part of a black hole, could just vanish. This would expose the singularity at its center but its just a hypothesis. Or better yet, a thought experiment at best. This wouldn’t eliminate its mass though.
WolfLink@sh.itjust.works 7 months ago
Basically.
They slowly decay as hawking radiation, but there’s nothing you can do to speed up the process.
Batman@lemmy.world 7 months ago
you just walk out. might need to build a bridge first
