“Time is weird. That much is obvious. Sometimes I think everything happens at once, which is anything but obvious and even weirder. I feel sorry for people who brag about 'living in the moment'; they're like people who come into the cinema after the film has started or people who drink Diet Coke—they're missing out on the best part. I think time is like the dial on a radio. Most people like to settle on a station with a clear signal and no interference. But that doesn't mean you can't listen to two or even three stations at the same time; it doesn't mean synchrony is impossible. Until quite recently, people believed it was impossible for a universe to fit inside two atoms, but it fits. Why dismiss the idea that on time's radio you can listen to the entire history of humanity simultaneously?”
