Entering an invisible doorway to catch a train at King's Cross station in London is a renowned fictional scene from the Harry Potter series. In recent decades, physicists have been trying to produce a similar effect by focusing ...
In 2017, astronomers witnessed the birth of a black hole for the first time. Gravitational wave detectors picked up the ripples in spacetime caused by two neutron stars colliding to form the black hole, and other telescopes ...
