HYPOTHESES

Were we to solve Einstein’s formula E=mc2, for m we would obtain the expression m=E/c2. However, both E (which stands for energy and c (which stands for the speed of light in vacuum) are quantities which refer to waves, with the latter referring exclusively to EM waves.

 How is it possible for quantities which refer to waves to define the mass of a material particle, if this particle is not comprised of EM waves?

 In that case, how is it possible for particles, if they are indeed comprised of EM waves that propagate at a speed equal to c, to be able to stay at rest?

The questions above are particularly simple, yet, the answers are devastating.

I believe that humankind will never cease to be fascinated by how Nature actually works.
