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 ...

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 ...

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 ...

Scientists claim to have found evidence of “negative time” after observing photons exiting a material before entering it. A team of quantum physicists from the University of Toronto in Canada made the ...

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.

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 ...
