Flapping a card in your hand at the speed of light is holding a card that is cube-shaped.

Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it.

We sometimes hear of things that can travel faster than light. Something called 'the speed of thought' is occasionally proffered. This is an exceptionally silly notion especially since the speed of impulses through the neutrons in our brain is about the same as the speed of a donkey cart.

Today, we commit to this next great leap into the cosmos because we're human, and our nature is to fly.

Nature decrees that we do not exceed the speed of light. All other impossibilities are optional.

Josh grins. "Just give me your hand."

"There," he says. "I've been waiting a long time to do that."
Not nearly as long as I've been waiting.
