Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

Essentially, the quantum metric creates a “geometric” drag on the electrons. When the magnetic field is applied, it breaks ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and effect unfold. That limit is usually described as the speed of light, yet the ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to new research that could help scale up an emerging quantum computing approach ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

The 2023 Nobel Prize in physics has been awarded to three scientists who created pulses of light so short they can be used to watch the inner workings of atoms. Pierre Agostini, Ferenc Krausz and Anne ...
