put strong magnet in both hands, same pole face each other, feel the repelling force/tension? yes.

now move 1 hand back and forth to the other hand, what do you feel?

that is the mechanism of light/em wave/photon/quantum.

instead of magnets, all electrons in the space are connected by electrostatic force f=ee/rr. they repel each other all the time. any 1 is moving, all other electrons share the force according to distance.

science told you light is wave or photon particle or mixed, all wrong, light is oscillating electrostatic force, there is nothing waving or passing space but vibrational em force.

after you understood all this, you will realize the sun will never cool down, all energy is shared by all masses in the space according to their mass and position/distance.

there is no nuclear reaction in the sun, the sun's energy is from its mass.

gravity is induced electrostatic force between masses.

similar to married couples sexuely attract other married couples.

mass is came from charges carried within it, the more mass equal to the more charges. 

electrostatic force decay at 1/rr, gravity decay at 1/rr, nature showed us gravity is induced em force, scientists just don't get it yet.
