Jorge Luis Borges wrote, "Time is the substance from which I am made. Time is a river which carries me along, but I am the river; it is a tiger that devours me, but I am the tiger; it is a fire that consumes me, but I am the fire," and it’s as close a definition as we have. But maybe if we slow time down enough, or speed it up enough, we can unlock its secrets. On this week’s Radio Lab, we’re using our hour to try and do just that.
