Damn The Theory - What About the Practicalities?

Boffins, labrats and other assorted Big Brains have concluded that photons can't travel any faster than the speed of light. So fucking what, I hear you cry. Bit the implication is that if there isn't anything we know of that can travel faster than the speed of light then theoretically time travel isn't possible.
Big fucking wow. Maybe, you're saying, scientists should be doing proper science stuff, like inventing things like flubber or a pill that makes fat arses thin. But, when I tell you of the practicalities of time travel you might change your mind.
If we could travel in time we could send someone back to the eve of the World Cup final in 1966 to shoot Geoff Hurst. That in itself would make the whole enterprise worthwhile...
Shoot Geoff 'Two-Goal Hat Trick' Hurst and end 45 years of (a) English delusions about how the ball 'might have' crossed the line and (b) the rest of the world (and the Scotchishers in particular) showing conclusively that it bloody well didnae. And the 'third' one should have been disallowed because there were people on the pitch; the ref should have stopped play. Geoff 'One Goal Hat Trick' Hurst it is then...
