Can photons really spend negative time? New quantum physics experiment on rubidium atoms challenges — What scientists know about time

A breakthrough quantum physics experiment has revealed a startling result. Scientists measured “negative time” as photons moved through a cloud of rubidium atoms. The study analyzed millions of observations and confirmed the effect using advanced weak measurement techniques. This negative time quantum experiment does not enable time travel. However, it challenges how researchers understand photon interactions, quantum mechanics, and the nature of time itself.
