what if you slide into a blackhole?
85170
Not long after "sliding" in to a black hole your body will be totally shredded down to individual atoms. When you stand here on Earth your feet are actually pulled downward more forcefully than your head. This is because your feet are closer to Earth's center of mass where the 'pull' of gravity is strongest. Same thing happens inside a black hole, only the difference in gravity pulling at your feet and head are many millions of time greater--you get ripped apart.

black holes happen when stars colapse.  Stars are massive fusion engines.  Their mass alone should make them colapse on themselves due to gravity but the nuclear fusion reactions going on in them where hydrogen atoms are being smashed together and forming helium atoms create huge constant explosive energy forcing the gasses in a star outward.  Eventualy the hydrogen gets used up.  The fuel for the star is gone and the star has nothing to keep it's mass from collapsing on itself.  All the star's gas molecules attract each other toward the center through the force of gravity and finaly all that mass which had taken up the space of thousands of planets is contained in the space of, ooohhhh I don't know a bowling ball.\n\nThat small ball of used up star has a huge density.  Density is mass divided by volume.  For example,  A nerf ball and a small marble may both weigh the same, but the nerf ball has a larger volume so the density is smaller and therefore the nerf ball is softer and if it has a density less than 1g/cc it will float while the marble will sink.\n\nSee when the the mass is in the numerator and the volume is in the denomenator is the volume.  As the volume (denomenator) gets bigger while the mass (in the numerator) stays the same the whole number gets bigger. \n\nThis is what happens in a black hole as it collapses.  It has the same number of gas molecules as it collapses but they get closer together and the volume gets smaller.  Let's say the mass of the star is 1 and watch what happens to the density as you divide it by a smaller and smaller number.\n\n1/10 = .1\n\n1/1 = 1\n \n1/.01 = 10\n\n1/.001 = 100\n\n1/.000 1 = 1000\n\n1/.000 01 = 10 000\n\nSee as the mass stays the same and the volume decreases the density gets bigger.  It quickly approaches infinity.  Math doesn't handle infinity well and we can't predict what happens at this point.  We call a point of infinite density a singularity.  \n\nThis singularity in a black hole has a huge density and huge gravity so nothing can get out, not even light, hence the name BLACK HOLE.  \n\nSo how do we know they're there?  We can see the efects of the black hole on other stars and Stephen Hawkins predicted that the black holes would actualy emit radiation which was detected proving him right and proving black holes.

You would rip a hole in the time space continuum...  \nIf you hit an egg with a  rod it explodes and you have to clean up...

stick a black ball in a middle of a usless disc. color the disc yellow because the black hole is very bright!

This is the process that your body, or any other object would experience when falling into a black hole.  You would be stretched out into a stream of atoms, one atom wide, falling towards the centre.  This is because under the tremendous gravitational gradient, the force pulling on your feet would be a lot stronger than the force pulling on your head, and you would also be squashed into a thin strand by gravity pulling both sides of your body towards a single point below the centre of your body.  An excellent and original science project if you were looking for one.

Once you cross the event horizon of a black hole there is no going back. You have essentially crossed into a different universe... or a part of this universe that is permanently cut off from the rest of it. \n\nBut, crossing the event horizon is not quite the end of your journey - in a large enough black hole you can cross this boundry without doing any harm to yourself, and it can still take millions (or more) years before you reach the black hole - the only problem is that you can never stay still, and you will always be getting closer to the centre. You can also never send signals back outside the hole (because light is also dragged towards the middle of the hole.)\n\nBut what's in the centre? The answer is 'a singularity.' This is a point where spacetime has infinite curvature. Still no help? Well... it's hard to describe, because we don't have a good enough theory of quantum gravity - quantum theory breaks down when things become very big, and gravitatinoal theories (ie relativity) breaks down when things become very small. A singularity is a lot of mass squashed up into a minute volume - so neither of our two best theories of the universe are much help.\n\nBut... if you want a mental image of a singularity, think of an awful lot of stuff squashed up so small and so dense that it rips a hhole in our universe.

No, u will stuck in center. As it is familiar that the earth is more or less spherical in shape. So the "point of gravity" lies at the centre of the earth (the core we say).\n\nSo when u jump into that whole (which u digged) u will go inside, due to gravity. Once u reach the mid point (core), the gravity becomes zero. But with the old force, u will move further, making negative gravity, (that is gravity in opposite direction), from the opp direction, u will come back to the centre. \nThis will repeat until the gravity becomes zero, after that u will stuk up at the core.

i'm assuming that you are ralking bout a hole being drilled right thru the earth and somebody falling into it...............you would accelerate and move towards the center and reach the opposite end of earth, at which point your velocity will reduce to zero and you will again move back to the cetre of earth and then onto the starting place.............in simple words you would execute Simple Harmonic Motion(SHM)

It creates a black hole.

The closer you get to a black hole, the greater the gravity gradient gets.  That is, the force of gravity is much stronger near the black hole than far away.\n\nAs you fell into the BH, the difference between the force of gravity at your feet and your head would become so great that your body would be ripped in two.  Then as the two pieces of you fell closer to the hole, the gravity gradient would increase still more, and the two pieces would be ripped into four.  This would continue until, by the time you reached the event horizon, you would be ripped into countless tiny pieces.  \n\nThe little pieces of you would fall through the event horizon, then continue falling and ripping into smaller pieces until they reached the singularity at the center of the BH.  No one knows what would happen then, because a sinuglarity does not obey the laws of physics that we know; gravity and density are infinite there.

First of all, you'd be stretched. Believe it or not, they call this process "spaghettification". Because gravity increases as you get closer, and a black hole has an amazing amount of gravity, your feet (assuming you're falling in foot-first) would fall faster than your head. When you reached the singularity, you'd be squished into a speck.\n\nThe weird part is that the people watching you from the ship would never see you go in. Once you reach the Schwarzschild radius, light itself cannot escape from the gravity. The light rays reflecting off of you would never reach back to the ship. Gravity bends light, so when the gravity is that huge, light bends 180 degrees backwards into the hole.\n\nAlso, relativity kicks in when the gravity is that high. People from the ship would see you fall in, slower and slower, until you stopped, because of time dilation. You'd see billions of years go by in an instant because of the same thing.\n\nAs for the wormhole thing, no one knows if they exist; they are purely speculation. Regardless, you'd be dead long before you'd ever come out somewhere else.

goes in the black hole ->O.\nonce past the point of Singularity which is believe to be much smaller than an atom's nucleus. then past the event horizon where time becomes irrelevant. and if that something is still in 1 piece, then it should come out to the white hole O->.

The black hole would suck that iron into it like soda through a straw.  Then if you could retrieve it, which of course you couldn't, it would be be cute and little, but you couldn't lift it and you probably wouldn't even see it.

assume that just for 1 second gravity goes off and comes back, what will happen??? is it possible??? no funky answers please. genuine replies are appreciated.

Refer to this article from Home Reference Library - Astronomy:\n\nWhat would happen if you fell into a black hole? Space is so warped around a black hole that you would feel a much stronger gravitational pull on your feet than your head (assuming you were going in feet first), and this difference would RIP you apart. \n\nSome say that if you could survive the tidal ripping and avoid the crushing force of the singularity at the black hole's heart, you might find yourself in a different universe.\n**\nNobody has gone through a black hole before (obviously), and it exerts such a powerful force on what is near it and goes through it, that it is literally impossible to survive going through a black hole. The article does not refer to time travel at the other side of the black hole, but perhaps if you survived it you'd find yourself in a different universe. That's cool, but basically impossible to survive one with our current technology.

Travel close to the speed of light or get really close to the event horizon of a black hole.\n(Well, you DID ask it in the physics forum!)\n\nIf you just want to relax, why not spend some time on Yahoo! Answers!!!!! It's fun.\n\n\n:)

actually scientist have a lot of theoretical knowledge of black holes. \n\nYou would fall until you were at the center(in a finite amount of time from your frame of reference), at which point you would be compressed almost to nothing. An outside observer would still be able to see you though for a while and things would appear stretched.  try wikipedia's entry on black holes. http://answers.com/black_hole\n\nRepeat? Where's the original?
