| Jul 15, 2018 at 17:16 | comment | added | Owais | I meant to say that photons have relativistic mass but how do they form electrons and positrons which are more massive than photons😊 | |
| Jul 15, 2018 at 17:13 | comment | added | ACuriousMind♦ | Can you be more specific as to why you think the photons' mass is relevant here? | |
