Would you float in the Centre of the Earth?

At the very center, the gravitational force is zero because there’s equal mass pulling on you from all sides, and it all cancels. If you built a room there, you could float around freely. That’s what it means to say that gravity is zero at the center of Earth.

What would happen to gravity at the Centre of the Earth?

So that even if we’re closer to the center of mass of the earth, gravity will not go up much. If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!).

Is there gravity in the Centre of the Earth?

Yes. There’s gravity everywhere – it’s an intrinsic property of all matter that has non-zero mass. If you were at the centre of the Earth it would feel like you were weightless. This is because all of the forces on you that result from the Earth’s gravity are balanced.

Can the earth’s core collapse?

The earth’s core is a blob of molten metal and stone, already compressed as far it could be under its own gravity. As far as we know, there are no hollows or bubbles inside the earth, because the total mass of the Earth matches with what we know of its composition and densities. Earth’s core cannot collapse.

How much would you weigh at the center of the Earth?

At the centre of earth, there will be mass but there will be no effect of acceleration. Hence, weight is zero.

Would you be weightless in deep space?

In orbit, there is only the gravitational force—leading to that feeling of weightlessness. Actually, you don’t even need to be in orbit to feel weightless. Since you are at rest, the total force must be zero—that means the downward gravitational force pulling down is balanced by the upward pushing force from the floor.

Would you be crushed by gravity at the center of the Earth?

Just getting to the center of the Earth and surviving is impossible. The Earth’s core is about 9,000°F—as hot as the sun’s surface—and would instantly roast anyone who found himself there. Then there’s the pressure, which can reach roughly three million times that on the Earth’s surface and would crush you.

What will happen if the core stops spinning?

When the molten outer core cools and becomes solid, a very long time in the future, the Earth’s magnetic field will disappear. When that happens, compasses will stop pointing north, birds will not know where to fly when they migrate, and the Earth’s atmosphere will disappear.
