Ok, heres the story
Lets say you build a tunnel straight to the center of the Earth, build a 1 cube mile of air (using cooling and solidifying techniques on the molten, of course) in the center. Now theoretically you would just simply float, since the same ammount of gravity is pulling on you from every angle (excluding the pear shaped earth [or banana shaped earth]) So there would be a kind of no gravity around you (exept when you float to one side of the chamber, you will start floating towards the middle since there is more gravity on one side than the one you are on)
Now here comes the question
Ive heard that there would be just wheightless ness. You would feel no pressure. Why is that? Its not like your in 0 gravity, just that gravity is pulling on you from every angle.
If you were to dig a tunnel straight to the center of the sun, you would simply explode from the incredibly gravity pulling on you, correct?

About the earth question, the earth gravity is constantly pulling on we, so in the center of the earth you would just feel ingravitation.
About the Sun I'm not sure, you can try to find info in google about that.

As for the Earth, I'd guess you'd die. The center of the Earth is where there is the most gravity applied to keep that little point together (which grows, and grows and etc... to give Earth).
If you do break that balance, lava will just rush so hard (preasure) that you'll just... Die.
And if you did freeze everything, GG us

Wait, now that I think on it, if in the middle of the earth there is no gravity at all, there would be an empty space. Is the core of the earth empty?!

I was under the impression it was some sort of fiery core, sorta like a seed in the middle of a peach.
And another thought: wouldnt the gravitational pull be relatively the same throughout, except when youre noticeably closer to the middle of the earth?

The earth is an oblique spheroid, not pair shaped. Every object with a mass has its own gravitational pull. There isn’t a center point in the core of the earth that produces all the gravity.
The gravitational force you feel is made up of the hugh masses of molten magma in the earth. So if you made a spherical gas ball in the exact center then you would not be pulled towards the center but you would instead be pulled outwards. Thus once you drift off one direction the pull on that side would become stronger and you would float to the edge of your air sphere. So balancing in the center of your imaginary bubble would be just as hard as hovering a marble under the edge of a vacuum.

A question I just though of, if under the crust of earth is a layer of molten rock then where did all the heat come from? (stupid question I know) but if you went to the center of the eart wouldnt the gravity just pull you apart from all sides at once because on the outer crust wouldnt the gravitaional field be weaker than the center, where it comes from?

The heat comes from the weight of all that is on top of it. The energy has no where else to go so it is converted to heat. I'm not a expert at physics but i would assume that the gravitaional pull in the center of the earth would be too weak to tear a human apart. But a person would die from the heat long before he reached the center anyways.

have you ever been on the gravitron
it would be exaclty like that inside the gravatron is he center of the earth it spins wich is the gravity pulling us away from the center,but if you got to the center you wouldnmt move because the gravity is spinnign around you,and besides if you went to the center of the earyh you would frigging burn to death,but thats not the point all im saying is the gravity goes around the center point like the eye of the storm cause a storm goes around one point and inside that point is the only area in the storm that you could survive in do you get what im saying that the gravity travels around the point and not through it but chances are you WOULD explode before you go to the center and you WOULd burn to death
ps:you would die on your way there its to much pressure for humans to survive and anything hollow that woyuld hold humans would be crushed sumply because it is hollow

Well, actually, even if there was one center point in the Earth, you couldn't be exactly at that point. You would have to be so small that you would be able to fit inside the atom at that center point. If you were regular-sized, gravity would pull on different parts of your body differently. You'd probably feel really screwed up, that's all.
My guess about the strength of gravity at the center of the Earth is that instead of the entire Earth pulling on you from one direction (down), only half of the Earth is pulling on you from every direction (up). Wouldn't the gravity pulling on you from above you cancel out the gravity pulling on you from below, and vice versa? That leads me to believe that you would feel no gravity whatsoever.

Stop complaining about how you would die on your way there..
It's a hypothetical question about if you were to somehow reach the center, how would gravity itself effect you.
Anyways, I don't really have anything to type, since anything I would have typed has already been typed.

Well I figured that if you went down there to the center, the Earth would want to collapse in on itself. The Gravity would be must more intense down there. It would want to pull your body to the exact center so your body would also want to collapse in on itself. I dont belive that you would feel no gravity.

can you prove for sure where the center of the earth is? I mean, if you were to begin drilling to reach the middle, and you didn't die along the way, wouldn't that shift where the source of the gravity is? I would think it would be like two very powerful magnets being slid across a field, one on the top and one on the bottom.
However, doesn't the gravitiy in the center of the earth have an effect on where it is in the solar system? If we were to shift the middle, than that might cause us to go plumating into a planet, or the moon plumating into us.
I could be way off on this, and I apologize. I haven't had much earth science classes, and I don't generally pay that much attention to them when I'm in them

Every object with mass has a gravitational pull. The chair you sit on roof above you they all have there own gravitational pull. If your were in the center bubble of the earth the mass would be all around you making you feel weightless. The center point isn't where the gravity comes from. Gravity isn't a thing, it is a force.
The gravity we feel on the earths surface is made up of all the ground mass below. The amount of pull is directly related to the amount of the mass. The moon has less gravity than the earth because it is smaller. The sun has more than the earth because it is larger. So much larger in fact that the earth revolves around it as it slowly falls to the suns surface. When compared to the suns gravitational pull, the earths gravity is insignificant, like the chair when compared to the earth.
PS. Its not earth science FireKame, its physics. Obviously some of you have never had it.

For the people that didnt understand what we are talking about:
1st you should know is that everything creates gravity, I create a very low gravity around my body, you too, my house too, etc.
Now look at the picture. If you are on the earth (circle #1) look at the "red" dirt, it creates a gravity that pulls to it.
If you are in the middle of the earth (circle #2). You have 1/2 of that dirt pulling you to up, and 1/2 of that dirt pulling you to down. The forcesare in the opposite direction so they cancell eachother, and the result is 0 gravity.

No squirel. Think about it as if your were in space.
Consider yourself suspended between two planents, both equal size and haveing equal pull on you. If you move closer to one of the planents then the pull from that one will be greator since your closer to it.
Moving away from the source of gravity does not make it stronger. Besides the extra earth that is left behind you doesn't amount to much. Most of it is off to the sides thus trying to pull you in a compleatly differant direction, not strait back.
The ¯ and _ on your pictures is above and below your comma. The land mass in those directions are trying to pull the person up and down and cancil eachother out. Of course were looking at a 3 diminsional scale so rather than just a top and a bottom you have a whole ring, but thats not important.
I love debating tihs kind of stuff.

Explanation:
Have you seen plant grow?
The root, no matter what, always grows down and the branches and trunk always grow up. Even if you started growing and then turned it upside down, the root will curve and grow down. Someone wondered how a plant would grow in 0 gravity so a method was used on earth to create 0 gravity. They used a rotator that rotates around a centre point (like a car wheel spinning) and plant some plants on the edges (which is like the black parts of the care wheels / tyres). However, the gravitational pull in fact still existed (created by the rotation) and the root grew to the centre of the wheel and the trunk grew outwards, the wheel is like the earth, the roots are growing towards the centre - which is the earth's core. Then someone planted a plant in the centre of the wheel, but this time the wheel is a completely spherical shape that rotated evenly. This time, the seed simply did not grow at all.

hmm lets see if you were to drill a hole to the center of the earth. Assuming you could survive the thousands of degree temperatures, once you got to the center you would be effectively stuck. Since at the center the gravity would not only be pulling at your feet but every inch of your body in some direction.
Going to the center of the sun again assuming you would survive the few million degree tempuratures and blinding light. You would not be stuck in the center of the sun you would simply be dead. Standing on the surface of the sun would crush you to something close to a atom think protein smear. Going to the center where the gravity would be pulling you at all sides simultaneously, you would get ripped apart.
