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:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
“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)
