We don't know for sure. We have theories.

>>9211814
You would know how it feels to chew 5-gum.

>>9211819
But i would love to hear theories, even personal ones no matter how autistic.

Die , its the void you would be crushed

>>9211814
the radiation and gravity would kill you before you even went in

It would be extremely painful

>>9212370
You're a big hole

>>9211830
It's not a void, you fool. That would imply there's nothing there. Just because nothing comes out doesn't mean there's nothing there, much can be contained within a black hole.

we're in a black hole right now

Die

>>9211814
There would be bookshelves that create a link to your past so you can send messages to your daughter.

>>9211814
You'd get burned to death by the firewall that's just below the event horizon.

You found jesus inside

>>9211814
Imagine all of your matter being compressed into an infinitely small and infinitely dense point in space. It's sort of like that.

>>9211814
you fall into a space of infinite bookcases where you go encode data to make a wormhole into a watch at your house using Morse code so your daughter will get it and save humanity.

you'd go into a library and communicate with your daughter still on earth

did you even watch interstellar OP?

>>9212372
For you

and you will accomplish all this using the greatest power of all

Literally nothing. You cease being part of the universe. What happens at that point is undefined from our frame of reference. Asking what happens after falling into a black hole is like asking what happens when you divide by zero, it doesnt.

>>9214448
Depends on what you divide by zero.

>>9214450
Fuck off with your semantics. Its undefined.

>>9214466

Blacks holes are the most interesting things in the universe precisely because in a sense they're beyond the universe. They're the ultimate cosmic clusterfuck, terrifying glimpses into infinity, things that evaporate due to obscure effects at rates that make our current universal time scale look like picoseconds.

I cannot wait for the first direct image of one of them in all its light-absorbing glory. Just a blob of pure negation amid the stars,ripping atoms into screaming jets of relativistic madness at its poles.

>>9211814
Taking time dilation into account, what would eventually end up happening is that, since the gravitational force surrounding the event horizon is so massive, time relative to those observing us would be much slower. As we would be pulled apart and reduced to atoms, we would be descending into the singularity at an infinitely small rate, st least to those on earth observing us. At least, this is how I think it might play out.

>>9211814
Do we actually know that they exist, or is it all just math on a white board?

>>9214726
Well, gravitational anomalies which satisfy the "math on a white board" have been discovered. So, yeah, they do exist.

>>9211814
literally nothing. The pure nothingness will destroy you to a point where even the physics of you being destroyed vanishes into nothingness

You live forever

>>9214474
On contraire, nothing could be more absolute than a black hole. They are literally the point where density equalizes with the speed of light and forcing all futures to point inward (because physics dictates nothing can be faster than time). They're a whole number in a universe of uncertain quantities and cosmic unfolding.

>>9214726
We know the Schwarzschild Radius must exist, and therefore black holes must exist.

>>9214712
Light is faster than time, so the idea that time stops at a black hole would only be relative to the omniscient observer, and an omniscient observer would not be bound by time simply by way of the fact their scale of observation would be greater than the relativity the black hole could affect. Miniature black holes are happening everywhere. In a sense you could say the splitting of the atom is a high speed decompression of the mass inside a black hole.

>>9212683

>>9216842
Cont.

So nothing would happen if you were sucked into a black hole. You'd just be neutralized by the singularity (the area around the black hole), but you would never actually become part of the black hole itself. You couldn't pass into the black hole unless there were some sort of collapse that compromised the Schwarzschild Radius through a shifting of the constant density. So you wouldn't be pulled apart at all. You'd just slowly float towards the singularity at a relative pace, almost lulling you to become one with it, and once you're within the event horizon, then you'd start to free fall rapidly as you approach infinite G's and then that's when you'd black out and wake up in the after life.

>>9211814
Maybe buy it a drink first?

Do black holes actually rip spacetime or do they just curve spacetime finitely

>>9211814
We ARE in one.

>>9217182
Deforms it finitely

>>9214474
Virgin detected

>>9217182
Depends on if string theory is right or not

>>9211814
Try sucking your item dick, basically the same thing, you end up in a infinite loop if shame

>>9217235
Why

>>9217182
The singularity has infinite curvature. The event horizon has finite curvature, in fact the curvature at the event horizon falls with the mass of the black hole, so there would be no noticeable effect at the event horizon for an infalling observer.

>>9217290
Correct.

>>9211814
Whelp, provided you can make it to the surface intact....
The you and the information of the matter that compromises you would become permanently encoded on the surface of the event horizon and after you passed through you would experience time in three dimensions.
Maybe.

>>9217340
That's okay with me.

>>9217290
How can it have infinite curvature?

Does that mean it's just a hole in spacetime

What is really meant by"curvature"

>>9217290
Instructions unclear, dick caught in accretion disk.

>>9217512
KY?

>>9217387
Yes, the way people deal with the singularity in mathematical terms is to remove that singularity from the spacetime manifold.
The curvature refers to the Riemann tensor, which is a geometrical object telling you how space is curved at particular point. From the Riemann tensor we can construct a quantity called the Kretschmann scalar, which is just a real number assigned to each point in spacetime, telling you how curved spacetime is at that point; it is a lot simpler than the Riemann tensor which not only tells you how much spacetime is curved, but also the manner in which it is curved. This Kretschmann scalar goes to infinity as one approaches the singularity at the centre of the black hole -- in fact, it's proportional to [math]\frac{1}/{r^6}[/math].

>>9217543
Oops, should be [math]\frac{1}{r^6}[/math].

>>9217618
yes a good a good. what if a baad??

>>9211814
It is merely twisted space-time.
You would fall in at the same rate as perceived outside. Then you would be crushed when you hit the solid mass inside.

Time would slow down as you approached the event horizon until you're rescued by alien archeologists 10,000,000 years in the future curious about the time in which you lived.

Don't say it won't happen, you would be gold to them.

>>9211814
i don't get why people are arguing about this? you would obviously die as you passed the event horizon because the part of your body that crossed cant communicate with the part that's outside the horizon. if you went head first into the black hole, you'd be decapitated

>>9217290
>The singularity has infinite curvature

>>9217927
Holy fuck you're retarded.

>>9217987
can you explain why?

Could you hypothetically get away from a black hole if you just struggled really hard to move?

>>9218126
A black hole's event horizon is a coordinate singularity, meaning it's an artifact of the coordinate system. The north and south pole are singularities in the latitude & longitude coordinate system, but spacetime isn't having a hernia there.

>>9218126
Imagine you are falling headfirst and your head has passed the event horizon. You send a signal from your head to wiggle your toes.

That signal will never reach outside the horizon, but your toes will wiggle.
Why? Because you, your head, your toes and that signal are all falling.
By the time the signal reaches your toes, they will also be within the event horizon.

>>9218181
Clever girl.

There is no such thing as a singularity.

It is though. It's called the electromagnetic field.

>>9218134
I dont think so
