Time is a fickle thing. Depending on your frame of reference, it can appear to pass slower or quicker, thanks to a wonky phenomenon known as time dilation that was described in Albert Einstein’s ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...
