The tau hypothesis

The Tau hypothesis is a theory in neuroscience suggesting that our perception of motion relies on a cue called "tau," which is the ratio of the remaining distance to a moving object and its speed. Essentially, it helps us gauge how soon something will reach us, allowing us to time our reactions accurately. For example, when catching a ball, your brain estimates tau to decide when to move your hand. This concept explains how we anticipate movement in our environment and coordinate actions smoothly.
