In physical cosmology, the quantum gravity epoch is the first era in the history of the Universe according to the standard Big Bang cosmology. In this era, the effects of quantum gravity such as fluctuating topology of space are commonplace. The temperature is comparable to the Planck scale. Other epochs such as the grand unification epoch follow afterwards.It lasted for about 10−43 seconds.
Famous quotes containing the words quantum, gravity and/or epoch:
“The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Here I sit down to form characters. One I intend to be all goodness; All goodness he is. Another I intend to be all gravity; All gravity he is. Another Lady Gish; All Lady Gish she is. I am all the while absorbed in the character. It is not fair to say—I, identically I, am anywhere, while I keep within the character.”
—Samuel Richardson (1689–1761)
“The death of a dear friend, wife, brother, lover, which seemed nothing but privation, somewhat later assumes the aspect of a guide or genius; for it commonly operates revolutions in our way of life, terminates an epoch of infancy or of youth which was waiting to be closed, breaks up a wonted occupation, or a household, or style of living, and allows the formation of new ones more friendly to the growth of character.”
—Ralph Waldo Emerson (1803–1882)
