There are several ways to disprove gravity.
1) Experimentally One simple experiment shows there is no gravity. The Helium Balloon. It rises. How is this possible?
Classical Mechanics shows that Force equals the Constant of Gravity multiplied by the Mass of Object 1 multiplied by the Mass of Object 2 divided by the Distance between the two masses raised to the second power. F=GM1M2/r^2 With this logic, the mass of the Earth is so great that the helium balloon would have no choice but to be attracted to the Earth.
We have mass 1 pulling on mass 2 and mass 2 pulling on mass 1. F1 = F2. This is just wrong. The force of the balloon that pulls the Earth is not equal to the force that the Earth pulls on the balloon. It would not rise. What we see in the experiment that the helium is rising to meet its level of density.
2) Commutitive The mathematics of gravity is a concept called Zero Point Mass. This is a mass without a volume. This is not found in the universe. The main problem here is the reduction of 3 dimensional densities to 0 dimensional masses. Once a density is reduces to a mass, the mass cannot be returned to the original shape of the density. So we cannot cube a zero and get anything but another zero.
This breaks the commutative properties of addition. Let’s look at some of the equations and how gravity fails at a fundamental level. F=ma : Force equals mass times acceleration. We have a zero dimensional mass * a 2 dimensional vector and that does not equal a 3 dimensional field.
