I tried rewriting it, but it was reverted and my addition put in a footnote, so I'm guessing I misunderstood it.

Just a couple of things. First unifying gravity and electromagnetism is not the same as unifying matter with light.

Also, further down it says that the energy of an atom has nothing to do with gravity. However, since both protons, electrons and neutrons have mass, there will be a gravitational component to the potential energy of an atom. Using an atom is a bad example, since the formula is talking about the energy associated with mass, and not talking about any other sort of energy. This is similar to how the formula for kinetic energy only tells us the kinetic energy component of a particle's energy, and says nothing about its potential energy. It would be better to talk about a sub atomic particle such as an electron here. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 12:06, 11 September 2016 (EDT)
