In general, you can't do that: There's no distance parallelism in curved spacetimes...
- bananabreakfast 7y agoWell, curved spacetimes only matter when you're dealing with gravitational redshift, which we aren't in this situation.
- cygx 7y agoWhy would you think that? FLRW spacetime isn't Minkowski space, thus has nonzero curvature.
