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 ...

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 ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...
