What happens to an object when it is sucked into a black hole?

Question

What will we theoretically find if we can go inside a black hole? Do the objects get destroyed or there is a seperate world there?

Answer 1

Holy crap... 19 answers so far and every last one is wrong (God's was the closest to being accurate, but that is NOT what Hawking Radiation is, if you want to know what it is really all about just post the question).

All the stuff people are talking about regarding physics breaking down and things getting ripped apart and squashed only applies at near the singularity. A black hole's event horizon (what we normally think of as the size of the black hole) extends WAY beyond that.

Someone mentioned the black hole that is believed to be at the center of our galaxy. If it exists, it can be as big as 20 LIGHT YEARS in radius. That's a lot of black hole where physics doesn't break down and we can still talk about what's going on.

So let's talk about it.

If you free fall into the black hole, you'll never know that you cross the event horizon. You are free falling which is an inertial reference frame and the principle of Special Relativity still holds, and will still hold, all the way down to the singularity. It'd be no different than if you were just floating around in space.

We won't find anything in our decent down to the singularity, save for what we brought with us / things that are falling along with us. Everything else will have already met it's doom before we got there down in the all consuming singularity.

At the singularity though, our models for physics break down and we can't say for sure what happens. We can say though, that immediately before you hit the singularity, the gravitational differences will curve spacetime enough to rip you apart. That only happens when you are close to the singularity though NOT the event horizon.

As far as a "separate" world, you could think of your life as you plummet down to the singularity at the center of the black hole, as being a separate world in the sense that nothing that goes on past the event horizon will ever be known by anyone outside the event horizon.

There's no other universes though.

Point of Techicallity: Black holes are theoretical objects and all this discussion is just theoretical. Also, the life I described inside the black hole only applies to ones that aren't spinning very signicantly / don't have a significant amount of charge. Simply put, ones where the Swarzchild Metric can be considered valid.

Answer 2

As it approaches the Event Horizon, the gravity becomes so intense, that even the difference in the length of an object creates enough gravitational difference because of the amount of pull from one end of an objecy to the other, that an object is pulled and stretched and is pulled apart(spaghetti). as the individual particles( it is argued how far matter is pulled apart before entering the event horizon), reach the Event Hoizon( a boundery defined as the point of no return, even light), that from the perspective of an outside observer, the observed object disappears, but from the standpoint of the object(now very small pieces), time then stands still. It is argued that nothing ever reaches the center of a Black Hole because as time is so warped that the effect of movement is forever halted. Oters speculate that even though time is not perceived from the objects standpoint, there is now no defined end point or center to get to. Cheers!!

Answer 3

No objects can enter a Black Hole. All the mass of any object is converted to energy and radiated as X rays as the object approaches a Black Hole.

Answer 4

I am going to resist the urge to ask if you were dropped on your head as a child. No, there is no alternate reality inside of black holes. If you are thinking of wormholes that is different, but a black hole is an immensely dense object in space that is the remnants of a large star (our star is an average size star) that has Supernovaed. Black holes come in all different sizes ranging from so small that we could theoretically drag them into the earths orbit and use them for power to Super-massive black holes that are theorized to exist in the center of all galaxies. When an object falls into a black hole (or more appropriately it is drawn into it) it is so dense that not even the fastest moving particles (aka light) can escape from it. It is so dense that physics in its most primitive forms breaks down, so that time itself no longer exists. Matter is broken down and returned to its original state- energy and is expelled from the black hole in the form of radiation. This expulsion was first observed by the physicist Steven Hawking and was therefore named Hawking Radiation for him. Wormholes on the other hand- all we know of them is that they are too unstable to be of any use to us at the present. But a wormhole would be used to travel across vast distances, not to live in.

Answer 5

Well, if something gets sucked into a black hole, it will probably be crushed because of the intense gravity that is said to have created a black hole. One scientific belief is that a black hole was once a star or planet that has "died" and no longer exsists, but the gravitational force which has become greater does.

Answer 6

there are several theories too, but this is the one I like the best.

When the black hole has the gravity that can suck within the vicinity of 2 million light years, for example, the body/material will extend to the black hole, so imagine a rubber band extending from a certain space in...er... space 2 million light years in distance. Anyway, when it dissipates in a certain time, the rubber band will turn to electrons... talking about cheap electricity...

Answer 7

science thinks that a black hole is just an object so dense and so gravitational that light cannot even escape.(hence "black")

so basically its like something the size of the sun compressed into the size of a marble.

anything that goes into a black hole gets crushed and smashed and becomes part of the black hole.

Answer 8

There are several theories. What is known is that the gravity exerted within makes it difficult if not impossible for light to escape. and so the phenomenon which can be as tiny as a pin hole can appear as large as a planet in space. What happens once something enters is still unknown.

Answer 9

One, black holes aren't actually proven to exist so there are only unproven hypothesis about what could go on in them. If they do exist than they are simply gravity wells that would crush everything that entered them. There would be nothing inside of them because everything would get destroyed.

Answer 10

Astronomers debate this a lot.

1) the object might emplode or explode.

2) it could be a short cut to another universe or galaxy.

3)It might allow us a means of time travel.

They just don't know yet.
