Scientists at the X-ray free-electron laser SwissFEL have realised a long-pursued experimental goal in physics: to show how ...

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 ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

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 ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

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