“I am confident, to more than nine nines of certainty, that not only has a fully-general means of causality-altering time travel not been invented, but that a fully-general means of causality-altering time travel never will be invented within our light-cone.”
“Excuse me, Academician – but how can you be so sure?”
“Are we, as we speak now, omnipotent deities the supremacy of whose mere whims is written into the canons of natural law itself?”
– from the proceedings of the Oroelle Conference on Temporal Mechanics,
7920, 8340, 8760, and 9180
Imagine someone builds the first time machine: It’s finally ready for it’s first test; the inventor throws the switch… and the time machine is powdered into a pile of monatomic dust. On top of the pile is a sheet of paper which reads:
“Hopelessly irreparable paradoxes threatened continued existence of galactic life. Only possible solution was to undo invention of time travel”.
This happens every time anyone tries to build a time machine.
Heh. I like it.
