Physicists find a loophole in Heisenberg’s uncertainty principle without breaking it

Abstract curly tendrils background.

Physicists have measured both the momentum and position of a particle without breaking Heisenberg’s iconic uncertainty principle.

In quantum mechanics, particles don’t have fixed properties the way everyday objects do. Instead, they exist in a haze of possibilities until they’re measured. And when certain properties are measured, others become uncertain. According to Heisenberg's uncertainty, it’s not possible to know both a particle’s exact position and its exact momentum at the same time.
