    Because this is a science thread I’ll be a bit pedantic. Mostly because I think it’s an interesting topic. It’s a mass-energy equivalence (≡) and not just an equality (=) they are the same thing.

    So it’s meaningless to say convert mass into energy. It’s like saying I want to convert this stick from being 12 inches long to being 1 foot long.

    You can convert matter (the solid form of energy) into other types of energy that are not solid. But the mass stays the same.

    It’s like when people say a photon is massless. It has energy and therefor mass. It just has no rest mass. So from the photons frame of reference no mass but from every other fame of reference there is mass.

      Yep. The Higgs field interacts with matter, both holding the waves it’s made up of “in place” (so it can seem macroscopically like it’s not a wave), and carrying a bunch of energy.

      There’s also mass-energy just in the very fast and powerful internal movements and fields of the nuclei and the individual protons and neutrons (which are made of gluons and quarks). Not sure about the breakdown off the top of my head, though.

      If you blew up an atomic bomb in a magically indestructible sealed container, it would stay the same weight, just with a noticeable contribution from pure electromagnetism now.

          That’s most of what I understand, honestly. It also connects to the weak force somehow, and I think other fields can have the same effect in certain case.

          I’m confident about the basic quantum mechanics of matter here, but I can’t actually do quantum field theory, so I guess I could still be misunderstanding something. Buyer beware.
