| Mar 3, 2019 at 16:48 | comment | added | dmckee --- ex-moderator kitten | The sign depends on your convention for writing 4-vectors or for forming scalar products. Obviously the convention used by particle physicists is superior in every way to that used by cosmologists. Obviously. | |

| Mar 3, 2019 at 15:59 | comment | added | Žarko Tomičić | Isnt it c squared times the mass squared with a minus in front? | |
| Mar 3, 2019 at 15:58 | comment | added | Eli | four-momentum squared Is always c square | |
