Physicists have done the seemingly impossible: found a way to track mysterious quantum particles even when those particles aren’t being directly observed.
In classical physics, an object occupies only one state of being at a time; something could be either alive or dead, for example, but not both simultaneously. But quantum physics, which seeks to explain how life works at the subatomic level, isn’t so intuitive. Quantum physics differs from classical physics in that under quantum theory, objects can exist as both waves and particles, occupying both states at the same time. They only exist as either one or the other after they’ve been measured, as a press release from the University of Cambridge explains.
Now, researchers from the University of Cambridge have shown that the movements of those particles actually can be tracked without measuring them first—by observing the way the particles interact with their surrounding environments, according to the press release. found a way to track mysterious
