Can electrons become protons?

A neutron-like shell formed about a positron makes it a proton. Proton exhibits all properties of its constituent positron. However, proton is huge with large numbers of primary 3D matter-particles in it, compared to electron, which appears as a single indivisible body. Therefore, electrons cannot become protons. read more

Electrons are indivisible protons are not. You can split protons into quarks but not electrons. Or so we believe at present. This is satisfying intuitively because protons are heavy and electrons are light. They both have the same charge. So we expect protons to be more than elementary. read more

are different. Quarks can be put together as protons, neutrons, and a wide variety of other particles. How they are assembled has a large effect on mass. Due to both quark mass and assembly details, a neutron ends up with more mass than a proton. read more

Actually, our sun is converting electrons and protons into neutrons all the time, to the tune of trillions of tons per second, in the form of proton-proton nuclear fusion. Two protons get close enough for the nuclear strong force to take over and allow them to fall together and fuse into one nucleus. read more
