The hypertime trap

摘要

Time ain't what it used to be. A hundred years or so ago, we thoughtrnthat the seconds ticked away predictably. Tick followed tock, followed tick. And clocks ran... well, like clockwork. Then along came Einstein and everything changed.rnHis theories of relativity dealt a blow to our naive ideas about time. Hitch a ride on a rocket travelling close to the speed of light, and time slows to a virtual standstill. The same happens if you park near a black hole and feel its awesome gravity. Even worse, space-time becomes so warped inside a black hole that space and time actually switch places.
