We live on a planet that never stops turning. As it spins, it travels around the Sun. All the while, though, we imagine we are standing perfectly still. Space is deceptive and so is time. We think of the past, the present and the future as destination points along a straight train track. Our physicists insist, though, that time is not linear. It, too, describes a circle - or, at least, a spiral. Your life now, is taking you back to where you have been before,moreover it insists that's not a mistake, it's a blessing.
