Why Is the Human Brain So Efficient? (2018)
World record tennis serve is 144 miles an hour and a human can't really move across a court and return a ball moving at this speed. If they're lucky they can reach it and react in time to hit it. I'm a bit confused by an article that claims tennis players can react to and return serves up to 160 miles an hour. I think evidence suggests that returning balls anywhere near this fast is dependent on analysing factors before the ball starts moving, the other players body position, racket position etc. Players have an intuition about where the ball is going to go without having to look at and analyse the flight of the ball.Just did some very basic checking.
Tennis court 23m
260mph = 72m/s
Ball takes approx. 0.3ms to travel length of court. 
human reaction time to visual simulous 0.25ms
So the idea is they move and hit the ball in the remaining 0.05ms?
Hmmmmm.
