Step on a crack, break your mother's back

This is an old children's game, anyone who trod on the cracks between the paving stones was out, until only one player was left, he or she was then declared the winner.

Step on a crack, break your mother's back– Most of us know the old rhyme “Step on a crack, break your mother’s back.” Whether the rhyme is the cause of, or a result of, this superstition is uncertain, though belief in it persists in many people today, even if subconsciously. Come to think of it, avoiding sidewalk cracks is probably a good policy for anyone who wants to avoid tripping.

once you go black you'll never go back

This statement derives from the general relativity theory published by Albert Einstein in 1915. It refers about the event in which an accelerated body crosses the spacetime boundary of a black hole known as the "event horizon". Beyond this boundary or "point of no return" the gravitational pull becomes so great as to make escape impossible and thus "you'll never go back".

"If a black hole is an oyster then the singularity is the pearl inside. The gravity is so strong it’s always hidden in darkness, beyond the horizon. That’s why we call it a black hole, once you go black you'll never go back."
