Scientists in China have announced the creation of pure-red perovskite light-emitting diodes (PeLEDs) that are the brightest and most efficient ever made. The breakthrough, achieved by a team at ...

Here we report a new method that permits the combination of very unusual properties of light in the focal region, permitting the creation of a ‘pure’ longitudinal light beam with ...

But there seemed to be no limit to its potential. The fierce pure light they were coaxing out of synthetic crystals was so powerful that the military believed its long-sought super-weapon—a ...

Now, a team of experts has described the creation of regular black holes from ... to explore concepts such as wormholes, faster-than-light travel and the resolution of black hole singularities.

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes.

Now, a team of experts from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has described for the first time the creation of ... faster-than-light travel and the resolution ...

Here’s how it works. For the first time, physicists have created a one-dimensional gas made out of pure light, and they want to use it to study how photons, or particles of light, behave on a ...
