Gravity is the most accurate measured fundamental force in the labs. Tyson pretends he does not know that fact. shame on him. Ask Tyson why didn't he answer my question? I sent him and 500 top physics professors around the world, no one reply, why? Professor, I think I discovered a new force, how do you think? Thanks Universal Repulsion - a new fundamental force. Similar to universal gravitation force between matters, there is an universal repulsion force between the line of sight electrons on the surface of matters. Without gravitation, we cannot orbit the Sun. Without repulsion, Sunlight cannot reach us. Because electrons are on the surface of all matters, and because the line of sight electrons are constantly repelling each other with Coulomb's force F=Ke x ee/R^2, therefore between the surfaces of matter A and matter B there exists an universal repulsion force F=Ke x aebe/R^2. In the equation, a is the number of lines of sight electrons on the surface of mater A, b is the number of line of sight electrons on the surface of matter B, R is the average distance. This universal repulsion force is always existing at any distance, therefore the line of sight electrons are constantly connected by this force at any distance, therefore they can share their kinetic energy instantaneously at any distance. This universal repulsion force is the conductor of light energy in the vacuum space between stars and planets. Light energy is instantly shared between the line of sight vibrating electrons on the surface of the Sun and electrons on Earth's outer atmosphere, then it becomes alternating current and traveling in the air at light speed C. This universal repulsion force is the conductor of light between things you see and your eyes. Due to air in between, light speed in air is C. This universal repulsion force is the conductor of alternating current between antenna and receiver. Due to air in between, light/AC speed in air is C. Due to the existence of universal repulsion force, all the star lights reach Earth's outer atmosphere instantly, become light waves traveling in the air at speed C. Sunlight takes 8 minutes to reach us is mistaken. Time delay in space communication is impossible. If light speed in vacuum space is infinite, relativity, electromagnetism, and quantum physics will be all wrong. Use MIT trillion frame per second camera to measure light speed inside of a vacuum glass bottle, we can prove light speed in a vacuum is infinite. Light only exists in the air, water, medium/matter. The light must coexist with the matter. There is no light in the vacuum space. Light energy instantly induced from the Sun to Earth's outer atmosphere due to the existence of universal repulsion force between electrons on the sun and our outer atmosphere. Einstein and Newton thought light is something traveling through space at light speed. It has both wave and particle properties. They were both wrong.
