Imagine
What is our actual Hubble "speed" ?
Bonjour,
Upon Hubble constant, recession speed is decreasing with distance (or time!-). That could be interpreted as deceleration but some persons articulate that as metric expansion (or metric expansion decelerating over time ?-).
What is our own recession speed? Zero ? Since temperature seams to decrease with time, is it, or could it be, related to CMB?
