Your theory on a black hole?

I’m a theoretical physicist (Ph.D., Stanford), and I actually had a chance to hear Steve Hawking lecture on the subject of black holes shortly after he discovered black-hole evaporation.

The basic “"spaghettification" story would be true for a moderate-sized black hole, if quantum effects did not exist. For an extremely large black hole, you would fall through the event horizon, and eventually be “spaghettified” inside the black hole, again if you ignore quantum effects.

But you cannot ignore quantum effects, as Steve showed.

So, how does the evaporating black hole thing change what happens?

Well… near a black hole, time slows down so much (gravitational time dilation) that you never really get into the black hole. It shrinks away by evaporation before you can actually get inside it. On the other hand, it is emitting radiation, towards the end fast and furiously rather like a super-enormous nuclear bomb, and you are in the midst of that radiation.

This is probably not a good thing.

Curiously, as the other answers here indicate, almost no physicists have bothered to reconsider the classic “spaghettification” scenario in the light of what we know now about Hawking radiation and evaporation (mainly because this is sort of a science-fiction scenario that most physicists consider a bit beneath them to really think through in detail – they’d rather spend their time figuring out what black holes look like from the outside to real astronomers).

There are still arguments about exactly how Hawking radiation works: for example, Steve himself recently conceded that he was wrong and that many of us (including me!) were right about a complicated issue of whether information can be lost in a black hole. (This is the only time I know of that I was right about something when Steve Hawking was wrong!)

So… there is no final answer yet to your question – we physicists are still figuring this stuff out. But the classical “spaghettification” scenario that ignores the hard Hawking radiation is almost certainly wrong.

well it actually depends on the type of black holes, you get sucked into. Some have stronger tidal forces than others and some have heavier radiation emitting than others. Some have lower temperatures. A Supermassive black hole is the most plausible to travel into and live because it emits little or no radiation, has moderate tidal forces, and relatively low temperatures. So unlike other black holes in which you would be stretched like a noodle called spagettification and incinerated, a supermassive black hole may allow you slip past the event horizon and into the hole itself which according to loop quantum gravity may harbor its own universe. Fascinating!!!!

Your brother is correct. It's important to remember that in science, a theory is NOT speculation or an educated guess. It is a description of how the world works based on what we know from observations and experiments. In this case, we know for a fact what will happen to you based on the laws of gravity. If you fell in feet-first, you would be both stretched lengthwise (vertically), and crushed horizontally. Probably not the best way to die.

You don't get sucked rather, you as matter, get attracted to it's enormous gravity. It would rip you up to shreds and you would become a part of the black hole at an unimaginable small size until the black hole spits you out. Sounds great.

in a small black hole... your brother is right... of course you would die long before you were spaghettified , but in a larger supermassive black hole.... you might survive quite comfortably inside the event horizon.. possibly for your whole lifetime if you have enough supplies, because the singularity is so much further away from the event horizon when the black hole has millions of solar masses.... perhaps even ... in theory... a planetary system inside the event horizon could host whole civilizations of beings for quite a long history of time.... before being drawn into the singularity

Ha!

Black holes are the Planet and Star eaters of the universe! They call that stretching "spagettification" btw so clever, i know.

I dunno- you can be crushed- since the pressure generated by black holes generates enough gravity to hold entire galaxies together (there is one holding the milky way together as we speak)

you could implode- since the sound of a black hole is 62 octaves below what humans could possibly hear- and since sound creates waves- that could tear us apart.

OR you could be transported to another part of the universe and die there-LOL! since some scientists speculate that black holes are tears in the fabric of the universe (wormholes) and you could end up elsewhere...

Thats a creative way to die. LOL!

I believe that the matter isn't destroyed or sent anywhere; I think it is just compacted all into the size of an atom or less. Possibly similar to the primordial atom that underwent the big bang.

it will crush you to less that the size of one billionth, zillionth of a pin head. And maybe even smaller than that

gonna die kaz gravity in front of u is way stronger than in back so u gona get riped in 100000000000 peices

your brother is correct

its called spagettification
