Lookback time in units of the hubble time

WebHubble 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 … http://astro.unl.edu/classaction/animations/intro/lookbacktimesim.html

WebThe dimensions of H0 are inverse time, but it is usually written H0 = 100h kms−1 Mpc−1 (2) where h is a dimensionless number parameterizing our ignorance. The inverse of the Hubble constant is the Hubble time tH tH ≡ 1 H0 = 9.78× 109 h−1 yr = 3.09× 1017 h−1 s (3) and the speed of light c times the Hubble time is the Hubble distance ...

This distance corresponds to its lookback time in years. For example, Star D is 1.75 light-years from the Observer star, which means that if it were to go supernova, 1.75 years would pass before the Observer would see it.
