Graham Storrs joins us on the blog to discuss all things TIME TRAVEL.
“Paradox is the poisonous flower of quietism, the iridescent surface of the rotting mind, the greatest depravity of all.” – Thomas Mann
What, you’re not a quietist? Never mind, we’ll come back to that.
As a writer of time travel novels, I spend a lot of time with paradox. It has become a friend. A shabby, disagreeable friend, I have to say, but one for whom I have an inordinate fondness. There are two ways of looking at paradox. Either it is a hideous monster of purest logic that prevents all possibility of time travel, or it is a sly creature of silken charm that whispers in the writer’s ear, urging creative trickery to make that story possible.
To be clear where I stand on the physics, let me just say that time doesn’t really work the way story-writers want it to. We don’t really travel in time. We travel in spacetime. Yes, you can describe space as a dimension something like the spatial dimensions to get a geometrical description of spacetime and, yes, it does seem as if you can move (in one direction) along that dimension at different rates. But consider this, if time is slowed in the vicinity of massive objects (which it is – ask Einstein), why does the Earth (a much smaller mass) not race ahead of the Sun in time, eventually leaving it far behind?
