(a) v=HR defines the Hubble constant. According to R=vt, the gap R between any two far-separated objects opens at a constant speed. The time interval t since the Big Bang is then calculated.
v=HvΔt→Δt=
<h3>What exactly is the Hubble constant?</h3>
- Hubble constant, in cosmology, a proportionality constant in the relationship between the velocities of distant galaxies and their distances.
- It expresses the rate of expansion of the universe. It is represented by the symbol
, with the subscript indicating that the value is measured at the present time, and is named after Edwin Hubble, an American astronomer who attempted to measure its value in 1929.
- Hubble established the cosmological velocity-distance law using redshifts of distant galaxies measured by Vesto Slipher, also of the United States, and his own distance estimates for these galaxies:
