I really hate to triple post but why does no one like to answer my extremely easy question?

Is it because
a, you are tired of virtual particles questions
b, question is too simplistic
c, too silly
d, others

EDIT: or e, is it one of the great unsolved mysteries in the physical sciences, there is no answer yet

Your view seams correct to me. Real photons can be measured and are quanta of electromagnetic radiation. Virtual photons cannot be measured and are used to describe interactions between charged particles.

Before I heard about Feynman diagrams and perturbation theory I thought about virtual particles like that:

If atoms decay or electrons get accelerated real photons get transmitted, since there is energy transfer. The ripples in the electromagnetic field transport energy, and photons are the quantum description of that process.

When there is a static electromagnetic field virtual photons are exchanged between the charges. Since there are no waves in the field, no energy is transported from one body to the other.

What’s wrong with that view?
virtual photons also existent in non-static electromagnetic .
