Some physicists believe that gravity is not a real force like the electromagnetic or the strong force because an inertial frame of reference eliminates the effects of gravity. However, it can be...

This question is ultimately about an electron’s structure. It is a common belief that an electron is a point particle. This view requires that we ignore the mass/energy in an electron’s electric...

Quantum field theory has a named field for each particle. There is an electron field, a muon field, a Higgs field, etc. To these particle fields the four force fields are added: gravity,...
