if the center of the Earth was hollow would you float around like you were in space.

How can a centre be around the edge of something?Wonderbread said:you change the position of the center of gravity if the Earth center was a hollow sphere, the the gravitational center would be around the edge of the spere equal in all directions,
Wonderbread said:The traveler accelerates toward the center of the Earth and is momentarily weightless when passing through the geometric center at about 7900 m/s or almost 17,700 miles/hr. The traveler would pop up on the opposite side of the Earth after a little more than 42 minutes. But unless he or she grabs something to hold on, they will fall back for a return journey and continue to oscillate with a round-trip time of 84.5 minutes.
The force of gravity in the center of the earth is caused by the immense amount of mass present in the core. The core of the earth is made up of mostly iron and nickel, which have a high density and therefore create a strong gravitational pull.
No, the force of gravity actually increases as you go towards the center of the earth. This is because the mass of the earth is concentrated at the core, creating a stronger gravitational pull.
The extreme pressure in the center of the earth does not significantly affect the force of gravity. While pressure can affect the density of the materials in the core, it does not change the overall mass and therefore does not greatly impact the force of gravity.
No, the force of gravity is the same at both the north and south poles of the earth's core. This is because the core is symmetrically spherical and the force of gravity acts towards the center of mass, which is the same at both poles.
No, gravity cannot be cancelled out in the center of the earth. The force of gravity is an intrinsic property of matter and cannot be eliminated. Additionally, the immense mass of the earth's core creates a strong gravitational pull that cannot be cancelled out.
