What Exactly Is Light?

Light and matter are both single entities, and the apparent duality arises in the limitations of our knowledge. - Werner Heisenberg

All these fifty years of conscious brooding have brought me no nearer to the answer to the question, 'What are light quanta?' Nowadays every Tom, D i c k and Harry thinks he knows it, but he is mistaken. - Albert Einstein

It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way. - Richard Feynman

Light is oscillating electricity carried by atoms on the surface of matters. 

Pass a laser beam through a vacuumed glass bottle, we can see it disappeared in the vacuum space. (We cannot see the surface of the inside glass wall repels itself)

Do the double slit experiment in vacuum chamber, wave property of light will be disappear. (All waves are co-existing with wave carrier/matter)

Light is visible frequency oscillating electrostatic force carried by vibrating atoms on the surface of matters

Light is not electromagnetic wave or photon particle propagating in space at 3 x 10^8 m/s.

The surface of atoms are negatively charged. Therefore line of sight surfaces of all matters repel each other with Coulomb's force F=Ke x Q1Q1/R^2. Scientists used to call it levity, I name it universal repulsion force.

Light does not radiate into space at light speed, light induces light throughout space through universal repulsion force instantly simultaneously.

Watch the moon, can you see the light beam from the sun to the moon? Why night sky is dark?

If sunlight exists in vacuum space, how can we see any stars?

Sunlight is circling earth constantly, it has never radiate in or out our atmosphere.

Atoms are formed from charged atom parts. Atom parts are constantly attracting and repelling each other under electrostatic force. Atoms are perpetual machines that constantly generating and transferring oscillating electrostatic force. 

So called EM wave is alternating current in the atmosphere produced by oscillating voltage in the antenna/atoms. 

Electromagnetic wave is misinterpretation of electrostatic wave. Electromagnetic force is misinterpretation of circular electrostatic force. Electromagnetic radiation is misinterpretation of electrostatic induction.
