You explained NOTHING, just hand waived, and spouted nonsense.
But this has nothing to do with your em universe, where you say light from the sun is em therefore em us more important.
But you are forgetting......
Without the strong nuclear force there would be no atoms the sun is made of.
Without the weak force there would be no fission to create the interaction that make the em emission of light and the rest of the spectrum.
Lastly without gravity there would be no sun at all.
So you have to look at them all as a sort of team and the electromagnetic force, is only one of the four that create everything in the sun and under it.:)
So what does it cost you to have someone change a tire for you?
You are obviously weak on figuring out how to do such things. Or lazier than hell. Or both.
