I think everything here on earth is attracted to the earth and can't escape its gravitational field. This gravitational field is unlike the magnetic field that only attracts metals but rather a centripetal force created by earth's revolution and rotation around the sun. If the earth were sitting still, then everything will float and escape to space or the earth will dismantle itself. I think everything here will float if the earth revolves and rotates at a lesser speed. The lesser the speed, the higher we float.
