Take a 1 mile long ladder and make it topple over. Calculate the speed of the top end when it hits the ground and it will be funny. As they say, figures don't lie, but liars will figure. In "A Brief History of Time" Stephen Hawking talks about tachyons. These are (of course) those particles that exist in perpendicular space time. He then goes on to discuss how this means that the sense of time moves backwards in perpendicular space time. The notion that's interesting to me about this is that you have more and more history as you move towards the big bang. Which means at the moment of the big bang, infinite knowledge was present in perpendicular space time. It's inescapable.
