Hubble’s Law (officially known as the Hubble–Lemaître law) is the fundamental observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. This means that the farther a galaxy is from us, the faster it appears to be receding into deep space. This landmark discovery provides the primary empirical evidence that our universe is continuously expanding.

The mathematical relationship of the law is remarkably straightforward: v=H0×dv equals cap H sub 0 cross d
