(As … WebHubble’s Law is the framework around which we understand galaxies, how fast they move, and why the galaxies that are the farthest away from us seem to be moving away at a faster speed than the closer galaxies. Without Edwin Hubble’s paper, written in 1929, we might have a far less advanced understanding of how galaxies move through the cosmos.
