Which way does the gravity pull at the exact center of a large object?

Hypothetically, if the exact center of the earth or the sun was cool enough to not burn us alive and we travel there.  We dig ourselves a little room with the exact center of the room being the exact center of the earth.  My question is, which direction would gravity pull us?  Would we be pulled towards the nearest wall comparable to the centrifugal force of the spinning carnival ride?  Would we float around in the room since the gravity from all the mass of the earth is pulling us in every direction instead of down?

You would feel no force at all at the very centre. Indeed, if you were to hollow out a spherical cavity centred at the origin, you would feel no gravitational force anywhere in the cavity, due to the spherical symmetry and the nature of the force law.
