Navigate
In mathematics, ergodicity expresses the idea that a point of a moving system, either a dynamical system or a stochastic process, will eventually visit all parts of the space that the system moves in, in a uniform and random sense.
Many animals use the night sky to navigate: Dung Beetles use the Milky Way to roll in a straight line away from competitors; songbirds can recognize rotating star patterns to pinpoint the poleward region of the sky; and Bogong moths use the night sky to accurately migrate more than 1,000 kilometers.
