Webb15 sep. 2016 · From his quantum of energy—which he called a “primeval atom” 4 —his theory predicted that this was the material from which all matter—the stars and galaxies—was derived. He predicted that some form of background radiation, even cosmic rays, would be found, the leftovers of that initial explosion of matter into all the Universe. … Webb1 apr. 2013 · To describe in words the initial state of the universe he had recourse to metaphorical terminology, his favourite names being “primeval atom” and “fireworks theory”. One name he did not use was the “cosmic egg”, to which there are nevertheless several references in the literature, none of them with a source reference.

As the universe gets closer to the singularity (i.e. as we extrapolate to the past), the scale factor goes to zero - that's the meaning of very small.

In 1929, Edwin Hubble announced the velocity-distance relation for galaxies that led a paradigm-shift towards an expanding universe. Lemaitre expressed the idea of singular creation of the expanding universe from a primeval atom in 1933 [5] . WebbIn a US radio broadcast in 1949, steady-state advocate Fred Hoyle disparaged Lemaître’s idea of an exploding primeval atom as nothing but a ‘Big Bang’ – and the nickname stuck! Today, we no longer speak of a ‘primeval atom’, and Georges Lemaître has been inexorably saddled with the title ‘Father of the Big Bang’. Webb19 okt. 2001 · A letter Lemaître wrote to Nature magazine in 1931 was effectively the charter of what was to become the Big Bang theory. He theorized that this primordial explosion, occurring on ‘a day without yesterday,’ had burst forth from an extremely dense point of space and time. He began calling this the ‘primeval atom’. ione wa airport
