“Time travel..will never be impossible forever.”
“The best evidence that time travel is impossible is the fact that we haven't been invaded by hordes of tourists from the future.”
“To travel beyond our world is to change this present one forever.”
“Going back in time is impossible. Turning invisible is impossible. Balancing the national debt is impossible. Blood sucking creatures that have been documented since the beginning of time across the entire world? Not impossible.” “Next you’ll be telling me they sparkle in the daylight.” “No,” he said, giving me his first real smile. “Never that.”
“It is impossible to travel faster than light, and certainly not desirable, as one’s hat keeps blowing off.”
“The Lord never asks the impossible. Often the difficult, but never the impossible.”
