Theory and Simulation of Artificial Antigravity

This article shows that a rotation of an object can make antigravity, in which there is strong gravity that distorts time and space. At first, we derived the curvature tensors upon Einstein's field equation, using spherical polar coordinates, and then calculated the coefficients of the curvature tensors, to simulate the strength of each component of the tensors, assuming that the stress-energy tensor reflects the strength of the gravity. As the result, we conclude that antigravity can be made by rotating the gravitational field, if the gravity is strong enough so that time and space can be distorted inside of the object.
