Scientists have long been fascinated by how light interacts with matter. At the heart of this curiosity are photons—particles that carry light—as they pass through different materials. When photons ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

In a quantum experiment, scientists observed photons spending ‘negative time’ in a cloud of rubidium atoms. This is likely caused by the fact that photons move faster when exciting these atoms than ...

According to scientists at the University of Toronto, “negative time”, which was previously considered an illusion, has turned out to be measurable through quantum mechanics. This discovery contests ...

Scientists have long known that light can sometimes appear to exit a material before entering it -- an effect dismissed as an illusion caused by how waves are distorted by matter. Now, researchers at ...

The groundbreaking experiment at the University of Toronto involved firing photons into a cloud of ultracold rubidium atoms. As these photons interacted, a strange event occurred: the photons ...
