The Hubblle Law
Hubble's Law states that the universe is expanding, meaning galaxies are moving away from each other. The farther a galaxy is, the faster it appears to recede, which suggests that space itself is stretching. This relationship is expressed as velocity = Hubble's constant × distance. It helps astronomers estimate how old the universe is and understand its large-scale structure, offering evidence for the Big Bang theory. Essentially, Hubble's Law reveals that the universe is dynamic and constantly expanding over time.
