One of the most glaringly obvious examples of what I am talking about is in very high energy particle physics, where an electron can scatter off a photon as if the photon were a hadron composed of separate point-like quarks.
Because the electron is moving at such high energies, from the frame...
How does that mean anything?
That would be the same case in normal annihilation too.
Yes, obviously the energy of the outgoing photon would be the same sum as the input in rest mass plus the energy of velocity of the two ingoing particles.
I wonder though, is it possible to have a different outcome depending on the reference frame?
It's well established in quantum theory that two different outcomes can simultaneously occur and it depends on your reference frame.
Can you explain why it would be impossible?
I do not see why it would not be possible under these special conditions.
The outgoing particle will still have the same overall vector and energy of the two beginning particles.
Unless I'm missing something very obvious, it seems both of your...
Can electromagnetic radiation escape from the event horizon of a Black Hole if the wavelength is long enough?
What if a Black Hole contains electric charge, hypothetically supposing we dumped a large number of protons into it? Electric charge is mediated by the electromagnetic force. So the...
I was reading about electron-positron annihilation. Typically it results in two photons, each with an energy of 511 keV, that go shooting out in opposite directions. But I read that in some instances three photons can result. Electrons have an intrinsic spin of ½, while photons have a spin of 1...
