swansont Posted January 13, 2015 Posted January 13, 2015 If you have an electron and an observer,if the observer accelerates does the electron emit photon? No. Acceleration is not relative. If the observer accelerates, then we know it is the observer who accelerated.
derek w Posted January 13, 2015 Author Posted January 13, 2015 No. Acceleration is not relative. If the observer accelerates, then we know it is the observer who accelerated. Does it matter what method we are using to observe the electron?
swansont Posted January 13, 2015 Posted January 13, 2015 Does it matter what method we are using to observe the electron? I can't imagine how it would. Acceleration is not relative.
derek w Posted January 13, 2015 Author Posted January 13, 2015 I can't imagine how it would. Acceleration is not relative. Does an accelerating electron emit a photon,because it is accelerating relative to its own electric field?
swansont Posted January 14, 2015 Posted January 14, 2015 Does an accelerating electron emit a photon,because it is accelerating relative to its own electric field? It's because of what happens to the field.
derek w Posted January 15, 2015 Author Posted January 15, 2015 If you have an electron in a vacuum chamber onboard a space ship,if the space ship accelerates does the electron radiate energy?
swansont Posted January 15, 2015 Posted January 15, 2015 If you have an electron in a vacuum chamber onboard a space ship,if the space ship accelerates does the electron radiate energy? Yes, though what happens depends on the details of what's happening with the electron. If it started at rest, absent any forces on it, it will remain stationary as the ship accelerates. Eventually it wills slam into the wall of the vacuum chamber, which would cause it to radiate. If it was accelerating along with the spaceship, it would radiate.
derek w Posted January 17, 2015 Author Posted January 17, 2015 Are all particles considered to be an excitation on the same field? Or is there an electron field for electrons,a positron field for positrons a photon field for photons,a gluon field for gluons etc? With energy being transferred from one field to another?

Or is there an electron field for electrons,a positron field for positrons a photon field for photons,a gluon field for gluons etc? With energy being transferred from one field to another? The latter. You can just think of different particles as being excitations in different fields, and those fields can interact with each other according to some rules we call "laws of physics."
