WebJun 11, 2024 · This theory was supported by Hubble when, in 1929, he found that there was a correlation between the distance of the galaxies and the amount of redshift in that galaxy's light. The distant galaxies were moving away faster, which was exactly what was predicted by Lemaitre's solutions. WebHubble also demonstrated that galaxies farther away from us are receding faster than those nearby – a fundamental observation now known as Hubble’s Law.
