‘Ultra-intense laser’ stops electrons travelling at near-light speed for first time, mimicking black holes

Education quantum physics science. Technology

Using a laser beam one quadrillion times brighter than the Sun, physicists have stopped electrons travelling at near-light speeds for the first time.

The experiment produced a quantum mechanical phenomenon that was previously only thought to occur around black holes and quasars.

This effect is termed a “radiation reaction”, and measuring how it works in a lab allows scientists to understand the processes taking place around distant astronomical bodies.
