The energy equation for a particle contains the rest mass and momentum. If the momentum is zero, all the energy comes from the term
. That means the particle still holds some energy. What is the form of that energy? For example string theory explains particles as vibrating strings, and I suppose we can think that the energy is stored as the vibration.
Another thing I can imagine is when we look at the electron- positron annihilation. The energy stored in the mass of these particles turns to a form of energy specific to motion, we can call kinetic. Can we say that these particles already had this form of energy within themselves? If not how do we call it and how do we explain it.
There is also a problem regarding the uncertainty principle that I was told it is related to this subject. If the position and momentum of a particle cannot be determined with absolute precision, does it mean that no particle can be at rest? If so, should it influence the rest mass? I think not.
