Hubble's law of universal expansion
WebThe Hubble time is the right age for the universe only if the expansion rate has been constant throughout the time since the expansion of the universe began. Continuing with our end-of-the-semester-party analogy, this is equivalent to assuming that you traveled home from the party at a constant rate, when in fact this may not have been the case.

Web27 apr. 2024 · The discrepancy between how fast the universe seems to be expanding and how fast we expect it to expand is one of cosmology’s most stubbornly persistent anomalies. Cosmologists base their expectation of the expansion rate — a rate known as the Hubble constant — on measurements of radiation emitted shortly after the Big Bang.
WebWorking with his assistant, Milton Humason, Hubble carefully measured the distance and Doppler shift of as many galaxies as possible. In 1929 Hubble published a paper that would lead to the realization that the universe was expanding.

WebUniversal Expansion. The Hubble relation is our primary evidence for the expansion of the universe. When Einstein, Lemaitre, and others solved the equations of general relativity, they were able to describe how the size of the universe has changed with time.
