What happens to the person when he is inside a black hole?
151381
The gravity forces between his head and his feet will be very different while he gets closer to the black hole, and this will make him strech like a spaghetti. Many other things will happen, but surely he will not live to see them.\n\nAfter many billon years, maybe his mass transformed in energy will come out of the Black Hole in the form of radiation, called Hawking Radiation.

A blackhole is a collection of matter with gravity so immense that nothing can escape how strong the pull of it is unless when you are in it's pull you can accelerate faster than the speed of light and beyond, thus the blackhole swallows up light as well.\n\nWhat happens is large masses collapse under their own weight. Think of a house of cards. The more you pile on, the greater the weight becomes until the cards on the bottom can't take the weight anymore. When the house of cards falls, the cards still exist but have lost their structure do to gravity.\n\nNow instead of a house of cards, replace that with an enormous sun that has tons of matter inside. The sun is teetering on the brink of collapsing as the matter inside grows and grows until eventually, like the house of cards, it falls down. Except since this is a sphere in space is is being pulled inward by it's onw gravity, and not down like earth gravity, the sun doesn't fall down, it falls IN.\n\nWhen this does happen the gravity doesn't stop existing because the matter doesn't either, it becomes smaller and the gravity grows as it pulls larger and larger amounts of matter into it's core. Eventually it because so dense and so massive and so small that the gravity involved will not allow even Photons, or light particles, the fastest thing in the universe to pass through it.\n\nThere ya have it!

Nothing; the "hole" in space isn't like a hole in your shirt, but rather like a giant pit.  What falls in stays in (of course, this is a three-dimensional hole that sucks stuff in from all directions, but we'll stick with the hole-in-the-ground analogy for simplicity)\n\nWhat has been discovered mathematically by people like Hawking and Chandrasekhar is that black holes actually do give off radiation (so-called Hawking radiation) through its effects on local space-time right at the event horizon.  At this specific region of space, charged pairs of virtual particles appear, and every now and then, rather than rejoining and annihilating each other in a tiny flash of light, one particle escapes and goes flying off away from the black hole while the other gets drawn in.  The escaping particle is considered matter, while the one getting drawn in becomes antimatter.  As the antimatter reaches the center of the black hole, it cancels an equal mass of matter and the black hole gets infinitessimally smaller.  An old black hole (one that has consumed all the matter in its vicinity) therefore gradually "evaporates" over a VERY LONG TIME (about 10^61 times the age of the Universe for a 30 solar mass black hole!) until its mass is so small that its gravity is no longer strong enough to hold in light, and it may do any number of things -- explode, fade out and become a really big hunk of red-hot metallic stuff, sit and remain a giant, dark gravity well... depends on what kind of math you like and the current theories at the time you calculate it.

There's most likely not an 'other side'.  A black hole is a bunch of matter that's been compressed down into a singularity, or an extremely dense spot.  More stuff falling into the hole isn't going anywhere; it's just contributing to the density of the black hole itself.

Nothing will happen. THere is no sense of time when travelling at the speed of light. No time - nothing happens.\nYour clock is stopped cold.

It depends on the mass of the star in question. For example, a star is born, it grows old, it gets larger (Red giant stage) and it dies. Depending on its mass and newly discovered turbulence inside a star before collapse, it will either go supernova and create a planetary nebula and reduce to a white dwarf, or go supernova, continue to collapse and turn into a black hole. It all depends on the mass of the star, and the amount and directionality of the turbulence inside the star's core.

well no one would know because no one can escape from a black hole not even light, the fastest thing in the universe, can escape. some scientist believe that everything in a black hole is singularity which means everything is one dimension. well it won't take you across the universe Wat he/she means is that inside a black hole there may be planets stars rocks gases and so much stuff that it would be considered a universe. or he is mistaking it with a worm hole but like the guy above me said there is no evidence that they exist.

Black holes are huge concentrations of mass in a very small area.  So small that it is too small to contain conventional matter as we understand it.  There is a perimeter around a black hole known as the event horizon.  Beyond this point, nothing, not even light can escape the gravitational pull of a black hole.  If you were to be able to stand on the event horizon and have telescopic vision like Superman, looking tangent to the event horizon, you would see the back of your head.

The photon sphere is the area around a black hole where photons travelling at a tangent to the sphere will become trapped in orbit. (link1) Inside the photonsphere it is impossible to orbit the hole, but you can still escape from it, and you can even hover between the Schwarzschild radius and the photonsphere - if you accelerate hard enough!\n\nWithin the ergosphere (but outside the event horizon) it is impossible to stand still - the gravity and rotation of the hole drag you arround even if you are travelling at lightspeed. But the rotation means that you can still escape, so long as you do not cross the event horizon.\n\nThe event horizon is the real 'do not cross' boundry of the black hole. Within the event horizon the escape velocity is greater than the speed of light, so if you get in there, you're stuck. Outside the event horizon, you can escape if you try hard enough.\n\nThe second link has a lot of good info on blackholes.

No one knows for sure.  The force of a wormhole theoretically can rip someone apart.

It creates a black hole.

unless this is a "zen" question, it doesn't "go" anywhere.  A black hole is a former star that has died and collapsed in upon itself and had its mass "infinitely" compressed into a tiny tiny volume.

A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it except through quantum tunnelling behaviour (known as Hawking Radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can let one exit a black hole. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.

Yes...and just paid off his bet to John Preskill in regards to whether information can escape from black holes.\n\nIn 1997 the three cosmologists Stephen Hawking, Kip Thorne and John Preskill made a famous bet as to whether information that enters a black hole ceases to exist -- that is, whether the interior of a black hole is changed at all by the characteristics of particles that enter it.\n\nIt now looks like Stephen Hawking and Kip Thorne may owe John Preskill a set of encyclopedias of his choice, since physicists at Ohio State University 'have derived an extensive set of equations that strongly suggest that the information continues to exist -- bound up in a giant tangle of strings that fills a black hole from its core to its surface.'

Yea, entering a black hole might not be the smartest idea...unless you like being compacted into a space smaller than your fingernail.

Black holes are food for my brain and curiosity. I love the subject it is so interesting!\nBackround info: A black hole is a concentration of mass great enough that the force of gravity prevents anything from escaping from it except through quantum tunneling behavior. The gravitational field is so strong that the escape velocity near it exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word "black." The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return. Theoretically, black holes can have any size, from microscopic to near the size of the observable universe.\nBlack holes are predicted by general relativity. According to classical general relativity, neither matter nor information can flow from the interior of a black hole to an outside observer. For example, one cannot bring out any of its mass, or receive a reflection back by shining a light source such as a flashlight, or retrieve any information about the material that has entered the black hole. Quantum mechanical effects may allow matter and energy to radiate from black holes; however, it is thought that the nature of the radiation does not depend on what has fallen into the black hole in the past.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying supernovae and X-ray emissions from active galactic nuclei.\nMy answer 1)time travel when you, or in this case an object, goes fast the world goes slow. and if something, a black hole, is going, or sucking, fast enough, the world around you will eventually begin to reverse.

First, due to the extremely low pressure- 0 pascals - all of the liquids in your body have their boling/freezing points lowered to the same temperature; all of your exposed fluids will boil: tears on eyes, saliva, urine (depending on the person's ability to keep his or her cool). Then, the capillaries around and on your eyeballs and other mucous membranes would rupture, spraying boiling blood into space. After about 20 seconds the normal person would be unconcious, though NASA trains its astronauts to last a full minute. After about 3 minutes you would succumb to suffocation, and you body would drift to space, nearly perfectly preserved, until:\n-It finally reentered Earth's atmosphere (assuming you were in Earth's orbit), where it would vaporize; \n-It hit another space object, such as an asteroid; \n-It is pulled in by another planet. \nIt all really depends on your location.\n\nP.S. contrary to popular belief, you would NOT explode. Your body structure and skin tautness will prevent that; however, you will probably reach a very unsightly level of bloating.
