Whether or not “negative time” becomes an accepted term, the insights it represents will likely influence the trajectory of quantum physics for years to come.

Quantum debate heats up: Divisive ‘negative time’ among scientists. It has already caused heated discussions in the scientific world. Prominent physicist Sabine Hossenfelder dismissed the terminology ...

“It took a positive amount of time, but our experiment observing that photons can make atoms seem to spend a *negative* amount of time in the excited state is up!” wrote Aephraim Steinberg, a ...

While the term "negative time" might sound like a concept lifted from science fiction, Steinberg defends its use, hoping it will spark deeper discussions about the mysteries of quantum physics.

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 ...

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 ...

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...
