This video explores Edwin Hubble’s seminal 1929 paper that changed our understanding of the cosmos forever. We dive into the numerical connection between the distances of galaxies and their radial velocities, a discovery that laid the groundwork for modern cosmology.
Learn how Hubble used Cepheid variable stars to estimate the distances of "extra-galactic nebulae" and discovered a startling linear correlation: galaxies are moving away from us at speeds proportional to their distance. We examine the evidence for what we now call Hubble’s Law and discuss how these observations provided the first physical evidence for the curvature of space and the theory of an expanding universe.
