WebFeb 2, 2024 · As we have teased before, Hubble's law equation shows the proportionality of distance and speed for distant galaxies. v = H_0\times D v = H 0 × D where, v v — The speed of the galaxy (positive is away from us); H_0 H 0 — The Hubble constant; and D D — The distance to the galaxy. WebHubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the …
