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.

you just walk out. might need to build a bridge first

Are you capable of moving faster than the speed of light?

[–] CheeseNoodle@lemmy.world 2 points 2 days ago (2 children)

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.

[–] Fleur_@aussie.zone 4 points 1 day ago

Doesn't matter once your breaking constants

[–] pressanykeynow@lemmy.world 5 points 2 days ago

But travelling faster than light you can go to the past before you passed the event horizon.

or have a time dilation device from sg1, that is modified by replicators

[–] zaphod@sopuli.xyz 5 points 2 days ago

That's the fun part, you don't.

[–] HatchetHaro@pawb.social 3 points 1 day ago

same as you would anybody's hole: just pull out.

You'll be slowly radiated out one half of an entangled pair of particles at a time. Arranging for reconstruction might prove difficult.

You evaporate over billions of years via Hawking radiation.

Try more like trillions of trillions of trillions... repeat a few more times.

[–] pressanykeynow@lemmy.world 1 points 2 days ago

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.

[–] scarabic@lemmy.world 3 points 2 days ago

Well your information is preserved in the universe and that’s all any of us can really lay claim to anyway.

You can eveporate your way out of it, given enough time.

[–] dogs0n@sh.itjust.works 38 points 3 days ago (1 children)

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.

Generally speaking, as Hawking Radiation.

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.

[–] Pika@rekabu.ru 1 points 1 day ago

To be fair, we only recently actually saw a black hole, and before that, it was just assumed to exist by its gravitational effects.

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 3 points 2 days ago (1 children)

So if you walk backwards, every direction leads out. Easy!

[–] phoenixz@lemmy.ca 1 points 1 day ago

So if you walk backwards, every direction leads further in. Easy!

Exactly!

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.

[–] WoodScientist@sh.itjust.works 11 points 3 days ago (1 children)

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 5 points 2 days ago* (last edited 2 days ago)

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.

Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.

As a jet of energy, assuming you haven’t actually crossed the event horizon

[–] nikosey@lemmy.world 16 points 3 days ago (1 children)

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.

Just use the same technology that allowed you to enter a black hole without dying.

[–] JPSound@lemmy.world 19 points 3 days ago* (last edited 3 days ago) (6 children)

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.

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.

[–] YiddishMcSquidish@lemmy.today 4 points 2 days ago

And never trust it when it says "quick save" always make a manual backup!

[–] RizzRustbolt@lemmy.world 2 points 2 days ago

Find the Myotrope, invert your orthocameral orbit, grab your ankles, and hold on!

[–] db2@lemmy.world 24 points 3 days ago (18 children)

You wait for it to reach a critical mass and explode. Might take a little while.

[–] remon@ani.social 29 points 3 days ago

You're maybe thinking of white dwarfs. Black holes don't do that.
