Argue for your limitations, and sure enough they're yours.

So much of what we said sounded crazy, yet none of it was false... as if two theoretical physicists stood on stage to say that when we travel near lightspeed, we get younger than nontravellers; that a mile of space next to the sun is differnt than a mile of space next to the earth because the sun-mile space is curved more than the the earth-mile. Silly ideas, worth the admission price in smiles, but they're true. Is high-energy physics interesting because it's true or because it's crazy?

There are grand rewards for those who pick the high hard roads, but those rewards are hidden by years.
