How would one exit a black hole?
(lemmy.wtf)
You don't.
Are you capable of moving faster than the speed of light?
Maybe my farts are
Real
Pretty sure even that wouldn't work? Once inside all directions become further in, or all futures become further in, or some bullshit like that.
But travelling faster than light you can go to the past before you passed the event horizon.
Doesn't matter once your breaking constants
or have a time dilation device from sg1, that is modified by replicators
That's the fun part, you don't.
same as you would anybody's hole: just pull out.
you just walk out. might need to build a bridge first
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!
Find the Myotrope, invert your orthocameral orbit, grab your ankles, and hold on!
I don't know about exiting but I like Entering A Black Hole Backwards followed by Chilly Water.
You evaporate over billions of years via Hawking radiation.
That assumes black holes aren’t the Big Bang white hole events of new pocket universes of the fizzy foam multiverse.
You could be part of a whole new universe! You wouldn’t know it, but how fun!
Try more like trillions of trillions of trillions... repeat a few more times.
Luckily time flies fast inside.
As if being shredded to atoms wasn't harsh enough, you don't even get keep your neutrons and electrons in this process. I guess it still counts as "exiting" the black hole, but just barely.

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.

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.
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.
I love how mind bending it is imagining what lies inside a black hole. Everything we know about physics may essentially go right out the window beyond the event horizon.

You wait for it to reach a critical mass and explode. Might take a little while.
You're maybe thinking of white dwarfs. Black holes don't do that.
Do they do that? Is that what the Big Bang was?
They don't. They do evaporate though.
That's a hypothesis though, right? They haven't detected any yet afaik (which the article could make clearer in its introduction).
Yeah, it mentions it at the end under the "Experimental observation" section.

More or less. In my layman's understanding: Black holes 'evaporate' slowly through Hawking radiation, losing mass as a function of their surface area (simplistically, particle/anti-particle pairs 'pop out of nothing' near the event horizon, one gets swallowed up the other escapes, this means a net loss of energy, which has to 'paid' by the black hole losing mass, think E=mc^2^).
Since a black hole behaves (geometrically) like any other sphere, the proportion of its area to its volume will grow as the black hole loses mass (i.e. it will have more and more relative area the smaller it gets), this process speeds up over time thus ending in what I guess you could call an explosion (more a whimper than a bang, to borrow a phrase).
Part 2 of your question: We don't know.

Through the gift shop.
Just use the same technology that allowed you to enter a black hole without dying.
With super massive black holes, you could pass the event horizon and not even know it. To you, everything would remain relatively (no pun intended) comfortable. You could live for a couple days, falling towards the singularity before the gravitational gradient becomes enough to rip you apart, thus ending your life.

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.

Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
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.
You'll be slowly radiated out one half of an entangled pair of particles at a time. Arranging for reconstruction might prove difficult.
feed it taco bell
As a jet of energy, assuming you haven’t actually crossed the event horizon

No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.
