World Egg - in Modern Cosmology

In Modern Cosmology

The concept was resurrected by modern science in the 1930s and explored by theoreticians during the following two decades. The idea comes from a perceived need to reconcile Edwin Hubble's observation of an expanding universe (which was also predicted from Einstein's equations of general relativity by Alexander Friedmann) with the notion that the universe must be eternally old. Current cosmological models maintain that 13.7 billion years ago, the entire mass of the universe was compressed into a gravitational singularity, the so-called cosmic egg, from which it expanded to its current state (following the Big Bang).

Georges Lemaitre proposed in 1927 that the cosmos originated from what he called the primeval atom.

In the late 1940s, George Gamow's assistant cosmological researcher Ralph Alpher, proposed the name ylem for the primordial substance that existed between the big crunch of the previous universe and the big bang of our own universe.

Famous quotes containing the word modern:

    ... in the fierce competition of modern society the only class left in the country possessing leisure is that of women supported in easy circumstances by husband or father, and it is to this class we must look for the maintenance of cultivated and refined tastes, for that value and pursuit of knowledge and of art for their own sakes which can alone save society from degenerating into a huge machine for making money, and gratifying the love of sensual luxury.
    Mrs. H. O. Ward (1824–1899)
