Light is occilating electrical force carried by vibrating electrons on the surface of atoms.

All lines of sight electrons in space are directly repelling each other with force F=Ke x e1e2/rr. That force is inherited, co-existed, therefore it transfers electrons kinetic energy instantly.

Sun light speed is infinite in space. Only when it pass through matter/medium/air/water it has limited speed, due to F=ma, all matters have mass, can never reach infinite speed.

Light speed in a medium is the rate of induction of electric force in that medium. For example, light speed in air is C, in water is 3/4 C.

Light must co-exist with matter. There is no light is space. There is no energy in space.

Hold a strong megnet in each hand, same pole face to each other.

Keep two hands at a distance and feel the strong repulsion force.

Now if you wave one hand, what would happen to the other hand?

Will it wave instantly at same frequency and opposite direction?


The repulsion force between the two magnets is the carrier of energy.

Kinetic energy of the two magnets are shared over the repulsion force.


Electrons are on the outer surface of all atoms/matters. Electrons repel all lines of sight electrons directly with the strongest repulsion force in nature F=Ke x e1e2/rr.

All electrons are constantly vibrating on the surface of atoms due to thermo energy, that energy is shared with all lines of sight atoms/electrons instantly through the repulsion force between them.

This is the mechanism of radiation, light, em wave, quanta, photon and radiant energy in space.

When energy transfer within matter, matter will wave with energy and show wave property. If the energy is bigger than electrons biding energy, electrons will escape from the matter, this is the mechanism of photoelectric effect.

If you can feel and see any amount of force.

When you hole an electron in each hand, can you feel the repulsion force F=Ke x e1e2/rr between them?

Yes, it is a very strong force, the only force that you can feel and see between the two electrons.


Now if you wave one hand, what will you feel the other hand?

Will you feel the electron wave at the same time? Will it wave at the same frequency?


What is energy? Motive force? Electromotive force?

How can energy from one hand transferred to the other hand?

Is energy transferring between electrons instantaneous?

If you can hold the sun in your right hand, hold the earth in your left hand.

Can you feel the attraction force F=K x m1m2/rr between them? Sure, Newton's Law stands.

Now, if you move one hand, what will you feel the other hand?

Will you feel nothing until 8 minutes later?

Will you feel force F instantly at the same direction?


Gravity is inherited, co-existed between all matters, stars and planets.

Therefore it is instantaneous, indestructible and immortal.

If the sun has a quake, earth, moon and every planets will feel it instantly.

Understood?


Still believe LIGO detected

Gravitational waves from 1.3 billion years ago

From two so called black holes merged?

The nature has two kinds of forces.

Positive charges attract negative charges, attraction force.

Same charges repel each other, repelling force.

Those two forces made up/formed all the matters from charged particles.

Those two forces are the foundation of gravity and magnetic force.

Coulomb's Law F=Ke x pq/rr and Newton's Law F=K x m1m2/rr have been tested extensively, and all observations have upheld those law's principle.

If we can see force, we will see all the matters in the space are connected by force.

All the stars, planets, masses and matters are attracting each other with gravity.

All the electrons on the surface of stars and lines of sight electrons on the surface of planets are repelling each other.

Both forces are like perfect springs that connected all matters as one.

Forces are inherited, co-existed, instantaneous, immortal and indestructible.

Matters have to move, change, involve and reform following force.

Nothing is at rest, all things are changing.
