At the very center of the earth is the inner core, a 760-mile-wide ball of iron. Seismic studies show that it consists of iron crystals that are kept solid by tremendous pressure even though it is hotter than the surface of the Sun.
The strength of gravity at the center of earth is zero because there are equal amounts of matter in all directions, all exerting an equal gravitational pull. With such thick air, you eventually lose momentum and stop your yo-yo motion about the center of the earth. You would end up stuck floating at the center of the earth.
