In quantum mechanics, it is impossible to know both exactly where you are and exactly where you are going. This idea, known as Heisenberg’s uncertainty principle, has been a key part of studying the quantum realm for almost a decade – but now physicists are even more certain about their uncertainty.

Before quantum physics was developed, researchers seeking to measure an object more precisely simply reached for better measuring instruments. But in 1927,…
