Imaginary time, by the way, is a theoretical additional time dimension that eliminates singular points in theoretical analysis of spacetime, converting them into ordinary points rather than those in which the equations of physics have no solution. And no, I don't understand that.

(Incidentally, Oliver actually gets one thing slightly wrong, saying "T equals i time t" when he should say than "tau equals i times t." I may not understand this stuff, but at least I can tell a tau from a t when I read something in Wikipedia...)
