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.

It would suck for a while. Then it wouldn't.
Depends on how big the black hole is. Small, and we'll be ripped to shreds before the event horizon. Big and we'll be immortalized in an ever-shrinking amount of red shifting photons from the external perspective. From an internal perspective we'll also be ripped to shreds tho.
And his wife?
If you press the universal terminal button, type in the command for spawning a black hole, set the mass to 1 kg, you get something very spicy. It’s so small, that it evaporates pretty much instantly, which means that all of that energy gets released as hawking radiation and the end result resembles an explosion.
How explosive is the explosion of 1kg black hole?
E=mc^2 should cover it, proper physicists can give you a better answer. Either way, it’s a big boom. Wolfram says, it’s about 90 PJ, which is firmly in the nuclear weapons territory.
A lot Please, please, please, someone check my googled physics and AI math:
E = mc² = 1 kg × (3×10⁸ m/s)² = 9×10¹⁶ joules (90,000,000,000,000,000 joules)
or
~21.5 MEGAtons of TNT (by comparison, the Hiroshima bomb was ~15 KILOtons)
It would have a temperature of ~1.2 × 10²³ K (1,200,000,000,000,000,000,000,000 Kelvin) The sun is a 5,772 Kelvin.
Like a 'small' star, it would radiate energy of about ∼3.6×10³² Watts (3,600,000,000,000,000,000,000,000,000,000,000 W) The sun puts out about 3.8x10²⁶ Watts (380,000,000,000,000,000,000,000,000 W)
Final burst duration: less than ∼8×10⁻¹⁷ seconds, or slightly faster than it takes for your mom to drop her panties.
Now for the best part. All of that energy would emanate from a very, and I can't express this enough, very tiny spot, like a billion times smaller than a proton:
~1.5×10⁻²⁷ meters
A proton is about 10⁻¹⁵
From seemingly nowhere, instant God-boom. I like to imagine that whatever was next to it would just disappear, and then the shockwave would happen.
Again, I googled and used AI to run the code for the calculations, so..you know, correct me and downvote.
So it would resemble the beginning of the universe, but smaller. Neat.
So would it have a similar effect to a radiation bomb, but without the radioactive fallout?
No one mention this to the US military
I wouldn't mind being spaghettified
If it's very large and stationary, we could survive, couldn't we?
Edit: Now that I think of it, we could survive even getting into the rotating black hole, given it's massive enough (like the supermassive black holes are).
From my understanding, no. The center of a black hole is theorized to be smaller than the planck length at at least one "pinch" point. I believe you're mistaking surviving the event horizon with surviving the entire journey to the splat zone. You'll still be spaghett before the center. It'd be like hitting an impenetrable wall at the speed of light and coming to a complete stop, you'd be more like a bunch of neutrinos by the time you get there, I think.
Yeah, I didn't mean surviving reaching the center. But on the other hand, a singularity cannot exist (as far as we know), so what's going on inside the black hole is one big unknown.
I'd actually guess that we'd end up in an accretion disc first and would be ripped to shreds there due to all the other stuff in orbit and less from direct influence from the black hole itself.
If it's rotating, yes. All real black holes are, so you've got a point. The tidal force ripping happens in the accretion disk regardless, though. The spaghetti just forms nearly perpendicular to the hole instead of directly towards it.
There's a theory that we already are. That our entire observable universe is, actually.
I wouldn't have to set my alarm for work.
bad things probably
we'd probably die
It will be a fucking improvement.
it would all be torn apart in a process that's called the spaghettification
Mm, spaghetti....
We all die.
Don't get my hopes up.
If you're really interested in this stuff I highly recommend reading "black holes and time warps" by now Nobel prize winner kip thorne
Thanks, fixed.
The universe would be a better place
It becomes part of the black hole. Then it will be very slowly evaporated.
Essentially, it wouldn't really matter what happens at that point. 🤷🏻♂️
We'd suffocate and then be crushed.
Most likely is that we would die eay before anything would happen from radiation, intense magnetic fields and black hole gravity fucking up with all sorts of asteriods in orbit. Not expecting anyone to survive long enough to get anywhere near the black hole in reality
It seems it's already in one, it's so dark all around other than the sun.
We don't know. Forces in and near black holes break physics. There is tons of speculation, but speculation is all there is.
Nothing near a black hole breaks physics. And I'd argue that outside what the heck is singularity really breaks physics as we know it.
We literally took pictures of supermassive black holes, can see black holes eating stars, have the math figured out pretty well and we can see black hole collisions with gravitational wave detectors due to their rippling effect on the fabric of our space-time.
We knew they existed before we found them, because of maths, andthe math actually gets us pretty far. It's the singularity in the center, or past the event horizon that we can't know about, because reality is shy like that. It boggles my mind that we were able to look around and say "hey guys, I've been measuring stuff, like how fast things fall down, and well, you're not gonna believe this."
