Energy is electrostatic motive force carried by moving matter and vibrating electrons/atoms.

Energy must coexisting with matter. Therefore there is no light wave, no photon particle traveling in space at light speed.

All theories based on light speed in space is C are mistaken.

All energy is came from atom formation. Opposite charged particles attract each other to form atom, atom carries charged particles kinetic energy.

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. -Feynman

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. - Einstein

You must read and think to learn the truth. You obviously can think, read some basic physics first.
Learn what is matter, energy, motion, force, time. Make up your own mind. Don't read and believe, fake news is everywhere.

All theories based on light speed in space is C are mistaken.

You are the one who needs to read some basic physics.

no photon particle traveling in space at light speed.

I major in physics. Read and think. Tried to figure out the mystery of gravity since a kid.

Follow the logic, understood the mechanism, before accept any scientific theory.

Otherwise, how do you know it is true or not?

[Yahya A.Sharif]

Follow the logic, understood the mechanism, before accept any scientific theory.

if you understood the mechanism then you would accept c and photons.Because c is experimental.If you understood how c was measured then you would accept it.

All theories based on light speed in space is C are mistaken.

We know for a fact that light does travel at c in space. You just try to sweep that fact under the rug by invoking a conspiracy for which not one iota of evidence exists.

Otherwise, how do you know it is true or not?

Because it says things that we know are false.
 For example it says that the speed of light is not c,.
We know it is.

We also know that you do not understand science.

All the fuel we used in the past produced a lot of energy, how come earth temperature stays stable?

The Sun heats earth constantly, how come earth temperature stays stable?

Energy leaked into space? Energy vanished into space? How? What is the mechanism?

If earlier universe was hotter, now is cooler, where is the missing energy? Is energy really conserved?

[Kryptid]

All the fuel we used in the past produced a lot of energy, how come earth temperature stays stable?

The extra heat is radiated into outer space.

The Sun heats earth constantly, how come earth temperature stays stable?

The excess heat is radiated into outer space.

Energy leaked into space? Energy vanished into space? How? What is the mechanism?

Hot objects have fast-moving molecules. Molecules contain electric charges. An accelerating charge emits electromagnetic radiation. This release of electromagnetic radiation causes the hot object to lose energy and cool down.

If earlier universe was hotter, now is cooler, where is the missing energy? Is energy really conserved?

The Universe is much larger now than it was in the past. When you put the same amount of energy in a larger volume, the energy density (and therefore temperature) is lower.

What is the mechanism?

radiation

"Radiation is a process in which a body emits energy that propagates through a medium or through empty space, but is absorbed by other bodies."
