Peeling this out into its own thread for clarity:
How is time dilation of extreme reference frames (photons, black holes, intergalactic space-time) taken into account in Big Bang cosmology? Since from the POV of a singularity or a photon, their clocks have effectively stopped and any lower inertial reference frames have already run their whole timelines (reached max entropy).
Doesn't relativity mean that from the POV of any photon or black hole, all slower or lower-g bodies instantly age near-infinitely (and thus photons & black holes perceive the Big Bang as already over)?
How can there be any *absolute age of a universe with physically infinite options of inertial reference frames an "object" can attain?
