What mathematical relationship defines the Hubble–Lemaître Law using the Hubble constant ($H_0$)?
Answer
Velocity equals $H_0$ times distance ($v = H_0 d$)
The Hubble–Lemaître Law, formalized by Edwin Hubble, states that the recessional velocity of a galaxy is directly proportional to its distance, with the Hubble constant ($H_0$) serving as the constant of proportionality.
