What happens to physics when time is defined as the speed of light?

A lot! It is truly amazing! It is absolutely beautiful! If you are a person who enjoys science, then I believe you will love this theory. The first -- and most important -- implication for physics that occurs when time is defined as the speed of light is: elementary particles are "Balls-of-Light." In other words, matter is made of light spinning around itself.

This is very intuitive to most scientists, or anyone familiar with E = mc². It is well known that matter can be converted into energy and energy can be converted into matter. Why? Because matter is made out of energy. Matter is simply electromagnetic and gravitational energy -- that is, a form of "light" -- spinning around itself.

Matter is spherical, standing waves of electromagneticgravitational energy.

(When I say a "form" of light, I am literally referring to the geometry that the light takes the shape of. I am not trying to imply that there are different types of light.)

Spherical Harmonics

The most difficult aspect -- and the key detail -- to this theory, is understanding this kind of wave, understanding what is called a "standing wave" -- a standing spherical wave. There are many easy to understand analogies for explaining waves of all types, but the mathematics for describing spherical waves -- called "spherical harmonics" -- will be beyond most people. Heck, most of this math is still beyond me. To this day, I still do not have the mathematical skills to easily work with spherical harmonics. I find it far easier to visualize spherical harmonics than to try to describe them with traditional mathematical terminology.

Originally, I created the Ball-of-Light Particle Model solely by visualization. I visualize the electric, magnetic, and gravitational fields moving across and within spheres 3-dimensionally in my mind.

From my point of view, the biggest tasks left in developing the Ball-of-Light Particle Model -- to make it capable of predicting physical situations -- is for scientists to: agree on new definitions for Basic Units; to create a computer model of the cross product, E cross B = G with the appropriate constant, and to plug it into a supercomputer to see what the harmonics are!
