Scientists have used a first-of-its-kind technique to visualize two entangled light particles in real time — making them appear as a stunning quantum "yin-yang" symbol. The new method, called biphoton ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped for.

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

The Circinus galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...
