Explain Hubble s Law and its significance in un... - SS2 Physics Space Physics and Astrophysics Question

Hubble's Law states that the recession velocity of a galaxy is directly proportional to its distance from Earth. This means that the farther a galaxy is from us, the faster it is moving away. Hubble's Law provided strong evidence for the concept of an expanding universe. It implies that the universe is not static but rather undergoing continuous expansion. The law also led to the development of the Big Bang theory, which suggests that the universe originated from a singularity and has been expanding ever since. Hubble's Law allows astronomers to estimate the distances and velocities of galaxies, providing insights into the structure, age, and evolution of the universe.
