| Jan 13, 2013 at 18:08 | comment | added | anna v | You have already proven it yourself , it is called proof by "reductio ad absurdum" . When you reach conflicting solutions as you have, you have proven that the hypothesis, in this case that a real gamma can go into e+e-, is wrong. So you have proven it cannot. | |
| Jan 13, 2013 at 12:00 | comment | added | anna v | But it is not possible to have pari production in vacuum. The photon needs to interact with another particle . | |
| Jan 13, 2013 at 10:40 | comment | added | 71GA | Yes, but could someone than show me how can we mathematically derive WHY pair production in vacuum is posible? | |

| Jan 12, 2013 at 14:54 | comment | added | anna v | It is due to the fact that the photon has 0 mass whereas the electron positron pair will have a positive invariant mass. A third particle is needed with which the photon can interact so as not to come to a paradox. | |
