If the earth's core had burned out, and I was in it's exact center which way would I fall, or would I fall at all?

You would stay still and attracted back if you move in any direction...

depends where if falls.

I think,to a good approximation, at the centre you would not feel an appreciable gravitational field from the mass of the earth. \n\nIt's a nice result in physics that if you're on the interior of a spherical shell of mass then you feel no gravitational force. You can think of the centre as being surrounded by layer after layer of spherical shells of radius ~0 up to the radius of the earth.\n\nIf you do the calculation, once you start going interior to the earth the gravitational attraction varies linearly with distance from the centre-going from 9.81m/s^2 at the surface to 0 m/s^2 at the centre.\n\nOutrageous!

Let me ask you, what would it be like of you were at the end of the Earth? Would it be like a cliff that you could jump off? That is silly because the Earth is round. It has a finite surface area but no edge. The edge is the surface you are standing on. Every place on Earth is the edge. It is believed that in a similar way the 3D universe is curved in the 4th dimension, so that it has a finite volume but no edge. Or you could say you are at the edge all the time but don't know it since you cannot perceive the 4th dimension.

If you didn't die from the intense heat, you'd probably be weightless seeing as gravity would be pulling you from all directions.

It would change the Earth's rotation and the Earth would tilt on its axis. What if all of us asked the same question at the same time that violated one of  Yahoo's community guidelines? Would the system completely break down?

When you jump off that building, not only are you falling towards the Earth, but the Earth is falling towards you. That's an equal and opposite reaction. You just won't see it because it's minuscule in size, because the Earth is so much bigger than you are.\nLikewise when you hit the ground, not only do you stop your motion towards the ground, but the stop the tiny motion that the Earth had towards you. Again, an equal and opposite reaction.

middle layer would be mantle, center would be core.

Not unless the wind carries it because whilst the earth is spinning around rapidly, so is everything on it. If this were not the case, and a person jumped straight up into the air they would shoot of in a direction and this doesnt happen

Yes, there is gravity at the center of the earth, but it would exert the same force in all directions at once, resulting in a net acceleration of zero.  Therefore, yes, you would float in the same manner as if you were in outer space.

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?

Since I was standing upon the earth’s surface before I started to levitate, my body would have a certain amount of kinetic energy prior to the levitation.  Upon levitating, this kinetic energy would “propel” me in the direction of the earth’s rotation.\n\nSo would I come down in the same place?  That would depend upon the resistance of my body to the friction of the atmosphere and the direction of the prevailing wind during the time period of levitation.  It might be possible for a very strong wind to push me faster than the earth is rotating or to push me perpendicular to the direction of rotation.  Or even "backwards."\n\nIn an “ideal” experiment, with no atmospheric friction, I should land exactly where I left the ground, give or take the distance of one step.

Neglecting all factors, including air resistance, you would fall faster and faster until you passed the center going really fast, and "fall" up to the surface on the other side of the Earth, slower and slower, until you stopped at the surface on the other side. To someone standing there it would seem as if you had been been thrown up from deep in the hole just hard enough to reach the surface. The time it would take to go through the Earth this way would be the same as the time it would take to complete half an orbit around the world, or about 45 minutes.

What do you weigh at the center of the earth? Zero, because the mass of the earth is pulling you equally in every direction.\n\nYour weight is greatest at sea level. Of course your weight decreases as you go to Mt. Everest, because you are now at a greater distance from the center. \n\nBut as you go down, your weight decreases for a different reason. Now there is mass of the earth above you pulling on you in an upward direction. That is why you weigh zero by the time you get to the center. \n\nIf you are on the surface of the earth or above, the earth's gravity acts as though it is concentrated at a point at the center of the earth. When you are INSIDE the earth, as in Death Valley, earth's gravity no longer acts that way.

In earth's atmosphere there is gravity that comes from the core of the earth. In Space, there is no gravity or "Zero Gravity", which means space is does not move except for the obitization of the planets around the sun. But, space is endless, so, we could be falling but never hit because of infinate space. but i do not think we fall.

No way to know.  What is the shape of "everything"?  I think it is round and that if you go to one end, you'll end up back at the same point if you keep going the same direction.\n\nGood question.

You won't be warned.  The earth will just start moving.  The danger isn't the earthquake.  The dangers are the things that fall on you, the fires that burn after (assuming gas lines or electricity or some source of fire and fuel).
