Lemaître's Hypothesis

Lemaître's Hypothesis suggests that the universe began from a single, densely packed point and has been expanding ever since. This idea, known as the "primeval atom" or "cosmic egg," implied that the universe started from a specific origin in time, later supporting the Big Bang theory. Lemaître's work connected the observed recession of galaxies with an initial explosive event, providing a scientific explanation for how the universe evolved from a hot, dense state to its current expansive form. His hypothesis was a foundational step in understanding the universe’s origins through a combination of astronomy and physics.
