Famous quotes containing the words dark and/or matter:
“she drew back a while,
Then, yielding to the irresistible joy,
With frantic gesture and short breathless cry
Folded his frame in her dissolving arms.
Now blackness veiled his dizzy eyes, and night
Involved and swallowed up the vision; sleep,
Like a dark flood suspended in its course,
Rolled back its impulse on his vacant brain.”
—Percy Bysshe Shelley (1792–1822)
“In the best of all possible worlds, childbirth enriches a marriage. In the worst, it harms it. No matter how good their marriage is, most couples find that having a baby challenges their relationship.”
—Jean Marzollo (20th century)
