Hi, I was just wondering if heisenbergs uncertainty principal is about position and velocity (or energy and time),.. then how come we can know that a photon travels at light speed (its velocity) exactly and also know that it hit some detector (its position).(adsbygoogle = window.adsbygoogle || []).push({});

If we know the velocity exactly then the light must be everywhere at the same time right?
