A laser pulse hits an electron in a solid. If it receives enough energy from the light wave, it can then move freely through a solid. This phenomenon, which scientists have been exploring since the beginnings of quantum mechanics, ...

A new study sheds light on the bright outbursts of radiation that are created when a star is destroyed by a supermassive black hole. The outbursts do not necessarily form in the close vicinity of the black hole, but are created ...

Light is composed of electric and magnetic fields that oscillate perpendicular to each other. When these oscillations are restricted, say, along a plane, it results in polarized light. Polarized light is of great importance ...
