Question

Quizplus · Accepted Answer

The Hubble Law, which states that the farther away a galaxy is, the faster it is moving away from us, applies to the largest scales of the universe, such as superclusters of galaxies. It does not apply to the small-scale structures within galaxies, such as the solar system or atoms, or even within local groups of galaxies, where gravitational forces dominate over the expansion of the universe.
