Famous quotes containing the word universe:
“The illimitable, silent, never-resting thing called Time, rolling, rushing on, swift, silent, like an all-embracing ocean- tide, on which we and all the universe swim like exhalations, like apparitions which are, and then are not: this is forever very literally a miracle; a thing to strike us dumb, for we have no word to speak about it.”
—Thomas Carlyle (1795–1881)
