a black hole needs to be of a certain size for you to get stretched out
couple of km in diameter, but not sure
black holes thar size last for a very long time
only a micro black hole would evaporate in the time it takes to fall into it
but you can't fall into a micro black hole, it would pass through you and kill you

What about if object falls under certain angle, and just spins very long time inside, and even longer outside. And wen spagettification will start the black hole would be microscopic

have heard that everything that falls into a black hole will forever be visible on its surface until the hole is evaporated
so the astronaut will fall in, die and leave an afterimage
afterimage will shrink with the hole as it evaporates, become impossible to see and then disappear with the hole, turned into energy

>what will happen with my item
when you drop object into black hole it will most likely get absolutely anihiliated by sheer power of gravity tearing it to atoms levels. also the initial impact of whatever is left out of it on the surface of black hole (which also happens to spin really really fast) will probably turn it into unrecognizeable atomic mush. kinda like when you grind stale bread into pic related.

so questioning "where exactly is my bread" when all you can observe is unidentifiable tightly packed ball of both energy and matter is kinda null.

>what happens when it runs out of energy
explosion. black hole exists because its gravitational pull is strong enough to hold infinite amount of everything. but if our observations and theories are true, then black hole loses its energy by radiation. this implies after enough time the hole will lose enough gravitational pull which holds its together: all remaining material and energy will start to regain its original properties and dimensions. explosion.

now the real question is how long does it take for a black hole to deplete its energy to collapse. my guess is universe isnt old enough for anyone to seen it yet.

what is it about black holes that makes them the number one most popular popsci topic of discussion amongst the brainlet soience fangoys?
is it the comic bookish aspects of the spectacular, unrealistic and completely non disprovable conjectures which go along with the topic that make black holes so popular amongst the scientist posers and wannabes?

From the pov of an object what will happen? Will it just disappear during spaghettification? Because as far as we know this process should not make the object from his pov annihilate it until the process is done, but the hole will evoparate before annihilation from pov of the object

What if the hole will not have time to annihilate the object before it evaporates. The hole will disappear, but from the pov of object what will happen? It didn't Finnished its annihilation but the doesn't exist anymore

again, null type of question. as i said before, if our models of black hole are correct, they will very violently explode once they shrink enough that the gravitational pull isnt strong enough to hold all the mass and energy it accumulated over aeons anymore. the explosion will anihilate your object.

now if you dont believe into explosion scenario, the object will simply look like it went through centrifuge which accelerates to very high g levels: torn. the closer to the horizon, the stronger the gravitational pull. so if it was a space ship, its front would be completely gone, its middle most likely completely teared on multiple places as the material would give out and "least" damage would be in the back.

but again, considering how long it takes for hole to lose fraction of its energy via radiation, the probability of timing object getting sucked into the hole just as its about to collapse is... impossible.

the current theories talk about whole universe going cold and dark because all stars will run out of fuel and then space will be full of nothing but zrozen planets and black holes which will have enough energy to exist for millions times longer than the stars and the universe itself to that point.

that is why this is all theory: nobody observed shrinking black hole, we just measured it emits energy. as to how precisely this happens or how come some type of energy is not captured by gravity is unknown.

So it's likely in second scenario that the information about the object will go back to reality from the black hole, even though distorded. It would solve the information paradox

They would've been absolutely destroyed by tidal forces already.

I have experience with stretching cm wide black holes. What changes when they're bigger? What do they smell like?

A blackhole is just a whirlpool in space. Don't overthink it, everything works in the same way.

>A blackhole is just a whirlpool in space.
Its a border, not a whirlpool
Ever wondered as a kid (or dumb adult) what would it be to reach the end of the universe, if there was a wall? Well a black hole horizon is a universe wall.
Which is interesting because it would mean that space can have holes, like swiss cheese
But such holes would imply a change in the topology of space, because a hole isnt just created by stretching, but by tearing and reconnecting

It will get ripped apart from the gravitational forces before it even reaches the event horizon

No, it won't, if you were to fly inside a black hole and not die you would not see anything, as all the light entering from the outside would just instantly shoot to the middle, all you would see are periodic bright flashes.

You are continously elongated so the spagettification does not kill you. Idiots of general relativity did not calculate this, so they just guessed evaporation. But maths don't work like that.
