The observable temperature dependence of gravitation

Newton's inverse-square law of gravitation is the oldest standing mathematical description of a fundamental interaction. However, Galileo, Newton, and Einstein failed to explain the Anomaly of the Space-Probes and flybys. Moreover, they also failed to explain experiments on the weight reductions of a charged metal ball, a charged capacitor, and heated-up metals. They did not see that gravitation is actually a combination of effects. In particular, the formula E = mc² misled us to believe that all the gravitation is attractive. In fact, if gravitation is a force acting on the mass, it is a combination of at least attractive forces and a repulsive force. The observation of Galileo is actually incomplete, because the existence of repulsive gravitation can lead to neutral matter with different falling accelerations. The repulsive gravitational force is very weak and thus escaped detection for a long time. However, now the advancement of technology and theoretical developments allow a direct observation of the repulsive gravitational effects by using a sensitive torsion balance scale. In this article, we shall describe an outstanding experiment on observing repulsive gravitation done by Li Hua-Wang in Dan Dong, China. However, to have accurate numerical values of this dependence on the temperature still requires more work since such a relation also depends on the metal used. Nevertheless, it is worth reporting because the publication of this work would encourage more experimental physicists to get better and extensive detailed results.
