Is it too much to ask if two photons can combine to make a proton and an anti-proton?
I never heard of photons 'colliding' with each other since there is nothing to collide...
Is there any particle at all that would not make photons when it meets its anti-particle?
neutrino? anti-quarks? What about any very unusual particle?
Sorry to come at an odd angle on this one...
When matter is turned to energy does this mean that all the quarks and other particles are converted to photons?
I want to know if all particles can end up as photons (by any process at all).
Its important to me to know this.
Please answer only if you know the real answer without...
