The Hubble constant describes the expansion rate of the Universe, and the expansion may, in turn, may be decelerated by "regular" matter/energy, and accelerated by dark energy. It's more or less the norm to use the term Hubble constant H 0 for the value today, and Hubble parameter H ( t) or H ( a) for the value at a time t ... WebThe time-dependent expansion of spacetime is characterized in the FLRW equations as a function of redshift z by the Hubble parameter H (z). Under the assumption of ΛCDM, H (z) = H 0 * sqrt (Ω m (1+z) 3 + Ω Λ + Ω k (1+z) 2) (e.g. Wei & Wu 2024, Chen, Kumar & Ratra 2024, Verde et al. 2014, Farooq & Ratra 2013 ).
