Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

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 ...

Radiative shocks are a class of shock waves in which the transport and deposition of radiation play a central role in modulating the shock’s structure and dynamics. These phenomena are not only ...

With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 'frame-by-frame' look at how a ...
