Question

in yoyur own word explain how hubbles law provided evidence for the big bang theory

Answer 1

Hubble's Law provides evidence for the Big Bang because the law supports the idea of an expanding universe.

Hubble's Law states that the speed at which galaxies are receding from Earth is roughly proportional to the distance the galaxy is from Earth. Hubble's Constant acts as the proportionality constant in the exact equation.

By saying that galaxies farther away move at faster speeds is directly analogous to claiming that space is expanding, which is consistent with what the Big Bang would develop into.
