Yes.If we had a tall person vs a short person running a 100m race, each finishing at exactly the same time to an observer. They each wear a watch synchronized at exactly the same height before the race. Would the taller person's watch show a different time after the race had finished?
Also, would the observer record a different time if he were standing higher up?
Not sure. I think so, but i cant claim to understand how it works at all.
