Gears of the Tao (4) - The Teeth That Touch: Why Time May Not Flow
Gears of the Tao (4) - The Teeth That Touch: Why Time May Not Flow One of the strangest ideas in modern physics is that time may not actually flow. At first glance, this seems absurd. Everything in our experience suggests otherwise. We remember yesterday. We experience today. We anticipate tomorrow. The seasons change. Children grow. Leaves fall. Tea cools. The sun rises and sets. If anything seems obvious, it is that time moves. And yet, when physicists peer deeply into the mathematics of spacetime, something unusual appears. The equations themselves often do not contain a preferred direction of time. The universe seems remarkably unconcerned with what we call past and future. This creates a peculiar possibility: What if time is not fundamental? What if time is something that appears? --- Imagine a set of gears. Not one gear, but an entire machine. Hundreds of gears. Thousands. Each connected to others through intricate relationships. Looking closely at a single tooth, you...
