Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

Astrophysicists talk a lot about gravitational lensing, one of the more fun aspects of light’s infamous particle-wave duality. The phenomenon shows, in predictable and measurable ways, how the tiny ...

Scientists have unveiled a groundbreaking material capable of bending light in such a way that it renders objects invisible. This technological marvel draws upon advanced concepts in metamaterials, ...

Did you know that gravity bends light? In 1916, Albert Einstein published his general theory of relativity. And British astronomer Sir Arthur Stanley Eddington proved the truth of Einstein’s work with ...

New types of semiconductor devices that respond to light could be possible using materials called perovskites. The work, published March 3 in Advanced Materials, shows that halide perovskite crystals ...
