Recently Mr Ellis has been on fine form on his website. But this was just genius:
Warren Ellis - a man with more ideas than his head can possibly contain.
A teleportation device would be a little computer set up to run a single equation. And this equation would prove that you’re somewhere else entirely. You’d plug in the coordinates of where you want to be and press Enter. The machine would run, the equation would solve, proving to the entire spacetime continuum that you are in fact in the other place, and suddenly you’d be in the location relating to the provided coordinates. You wouldn’t appear inside another object, because the universe doesn’t like that. The only tricky bit, I figured, would be that the Earth moves through space around the sun and the sun moves through space with the Milky Way and the Milky Way is subject to the expansion of the universe. But people are clever and would find ways to allow for spacetime drift. I think that if you’ve cracked the mathematics to convince the universe that you’re somewhere else entirely, these small details would be easily attended to.This is, of course, why I don’t really take drugs anymore.
