Quantum Experiment Uncovers Evidence of ‘Negative Time’

 Quantum mechanics is a field where normal rules don’t apply, and reality behaves in strange ways. Recently, quantum physicists made a new discovery that adds to the confusion: “negative time.”

In a study, not yet peer-reviewed, researchers say they observed photons (particles of light) behaving in a way that suggests time can move backward under certain conditions.

Here’s what happened: when photons were sent into a cloud of atoms, they seemed to leave the cloud before they even entered. It’s a puzzling phenomenon.

As explained by Josiah Sinclair from the University of Toronto, a “negative time delay” means that if you used a quantum clock to measure how long atoms stayed excited (a higher energy state), the clock would, in some cases, run backward. Sinclair wasn’t directly involved in the new study but contributed to earlier research.....<<<Read More>>>...
