Famous quotes containing the word universe:

    Man is but a reed, the feeblest one in nature; but he is a thinking reed. The entire universe need not arm itself to crush him—a vapor, a drop of water suffices to kill him. But if the universe were to crush him, man would still be nobler than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this.
    Blaise Pascal (1623–1662)

    Failure or success seem to have been allotted to men by their stars. But they retain the power of wriggling, of fighting with their star or against it, and in the whole universe the only really interesting movement is this wriggle.
    —E.M. (Edward Morgan)

    The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.
    Steven Weinberg (b. 1933)
