A man said to the universe:
"Sir, I exist!"
"However," replied the universe,
"The fact has not created in me
"A sense of obligation." --Stephen Crane
Well, if not the Universe, then us. It might be worth investing in some sort of countermeasure for asteroids, as Neil deGrasse Tyson has argued for on numerous occasions. I imagine it’s possible that mining operations in the mid-21st century could accidentally dislodge or ‘lose’ asteroids being towed, and effectively ‘fling’ them at Earth. Or, maybe someone’ll go all evil Hollywood production and become a supervillian that hijacks a mining operation and threatens to bombard Earth with the ultimate missile launcher.
