Famous quotes containing the words orbit and/or earth:

    The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!
    —E.T.A.W. (Ernst Theodor Amadeus Wilhelm)

    Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.
    Gore Vidal (b. 1925)
