| Nov 9, 2018 at 2:30 | comment | added | user4552 | @JEB: "No preferred frame" still holds. The interpretation is the same as in SR: if we have some nearby matter that's in a certain state of motion, then we are free to use that matter to define a frame of reference. | |
| Nov 9, 2018 at 0:19 | comment | added | JEB | Two tenets of SR: "there are no preferred frames", and "nothing can travel faster than light", just don't apply on a cosmic scale. | |
