description Georges Lemaitre Overview

Georges Lemaitre was a Belgian scientist and priest whose work significantly shaped cosmology in the 20th century. He initially theorized that the universe originated from a single point, proposing what would later become known as the Big Bang theory. Utilizing Einstein’s general relativity, Lemaitre successfully modeled the expansion of the universe. His ideas were foundational for early astronomers and physicists seeking to understand the origin and evolution of space and time.

help Georges Lemaitre FAQ

What did Georges Lemaitre publish in 1927?

In 1927, Lemaitre published a model of an expanding universe based on Einstein's general relativity. That work connected galaxy recession with what is now called the Hubble-Lemaitre law.

Was Lemaitre a priest as well as a scientist?

Yes. Georges Lemaitre was a Belgian Catholic priest as well as a physicist and mathematician, and he was ordained in 1923.

What was Lemaitre's primeval atom idea?

In 1931, Lemaitre proposed that the expanding universe could be traced back to an initial state he called the primeval atom. That idea became an early form of what later came to be called the Big Bang theory.

How is Lemaitre connected to Hubble's law?

Lemaitre derived an expanding-universe relation in 1927, before Edwin Hubble's 1929 observational paper. In 2018, the International Astronomical Union recommended the name Hubble-Lemaitre law to recognize that history.
