Famous quotes containing the words dark and/or matter:
“O dark dark dark. They all go into the dark,
The vacant interstellar spaces, the vacant into the vacant,
The captains, merchant bankers, eminent men of letters,
The generous patrons of art, the statesmen and the rulers,
Distinguished civil servants, chairmen of many committees,
Industrial lords and petty contractors, all go into the dark....”
—T.S. (Thomas Stearns)
