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.

    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?

    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.

    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.

    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.

    Black holes don’t just roam around looking for planets to snack on.

    Don't be so sure. There's plenty of cases of black holes devouring entire star systems. There's so many black holes just drifting around that you could make a case that they are just roaming around looking for their next snack.

    If you're really interested in this stuff I highly recommend reading "black holes and time warps" by now Nobel prize winner kip thorne

    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. 🤷🏻‍♂️

    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.

    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."
