Question: how can we avoid spagetiffication (I hope I spelt that right)when entering a black hole and what causes hawking radiation

spagetiffication is a fantastic word, and I think it’s unavoidable, stay away from black holes kids!
Hawking radiation is to do with something called vaccum energy. Although space seems empty, its actually buzzing with pairs of particles that appear out of nothing then crash into each other and disappear again, all so quick the universe doesn’t notice.
However, if one of these particles appears in a black hole and the other one outside, then they can’t recombine and disappear. It’s these particles that are called Hawking radiation.

You can’t avoid spagetiffication, it is the laws of physics.
I explained Hawking radiation at another question. -

If you approached a sufficiently large black hole (like the supermassive one in the middle of the galaxy), you might* pass through the ‘event horizon’ without even noticing! You’d never be able to escape, though, and you would get spaghettified the deeper inside the black hole you went.
*I say ‘might’ because even if you weren’t pulled apart at the horizon, you might get burnt to a crisp by the boiling mass of particles on the edge caused by Hawking radiation. There’s still some debate about whether there’s a horrible ring of fire at the event horizon, though… o_O

Spaghettification, what a great and scary process isn’t it? Anyways, am I the only one that when hear this word thinks of an XXL portion of spaghetti? 😀

nope i used to think that it literally turned you into spaghetti and wanted to make a spaghetti farm in a black hole
