    Graduate Electron falls into black hole. what happens.

    you are right, didn't think there. So what happens then? What effect does the curved spacetime have on the electron?

    Graduate Electron falls into black hole. what happens.

    the electron falls and emits radiation. will it lose all it's energy by the time it reaches the event horizon or will it have enough (>2m) to produce a particle shower? Will other things happen?

    Graduate How Do Photon Degrees of Freedom Reduce from Four to Two?

    i haven't take a QFT class yet, but I'm learning ahead. any good books that cover gauge fixing or is it only published in journal form?

    Graduate How Do Photon Degrees of Freedom Reduce from Four to Two?

    what about real photons that couple to fermion fields?

    Graduate How Do Photon Degrees of Freedom Reduce from Four to Two?

    I just learned about the quantization of the em field. Then EM field 4-potential has components A^mu, giving you 4 degrees of freedom. That gets reduced to 2 degrees of freedom (2 polarization states), that gets done to impose the Lorenz gauge onto free photons. SO what the hell happens to the...
