Lasers emit a very small amount of gravity sakkmesterke/Alamy
Light is heavy. Powerful laser beams have a gravitational field, which warps the fabric of the universe around them and may help us understand how gravity behaves in the quantum realm.
Most models of light鈥檚 gravity are simple. They only take into account light鈥檚 behaviour as a particle but not as a wave when, in fact, it is both. Fabienne Schneiter at the Eberhard Karls University of T眉bingen, Germany and her colleagues made a mathematical model that takes into account light鈥檚 wave nature, illuminating its tiny but weird…
