Hubble radius, Hubble sphere (not to be confused with a Hubble bubble), Hubble volume, or Hubble horizon is a conceptual horizon defining the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time. Note that this does not mean the particle is unobservable; the light from the past is reaching and will continue to reach the observer for a while. Also, more importantly, in the current expansion models, light emi… WebWhile the tension in the Hubble constant has received much attention in recent years, it has been pointed out that the H 0 tension should not be considered in isolation, because there is an anti-correlated tension in the parameter r d.
