We are all glorified motion sensors.Some things only become visible to us when they undergo change.We take for granted all the constant, fixed things, and eventually stop paying any attention to them. At the same time we observe and obsess over small, fast-moving, ephemeral things of little value.The trick to rediscovering constants is to stop and focus on the greater panorama around us. While everything else flits abut, the important things remain in place.Their stillness appears as reverse motion to our perspective, as relativity resets our motion sensors. It reboots us, allowing us once again to perceive.And now that we do see, suddenly we realize that those still things are not so motionless after all. They are simply gliding with slow individualistic grace against the backdrop of the immense universe.And it takes a more sensitive motion instrument to track this.
