After monitoring a pair of pulsars in tight orbit around one another for 16 years, astronomers conclude that their behaviour is consistent with Einstein’s predictions
For more than 100 years, Albert Einstein’s general theory of relativity has been our best description of how the force of gravity acts throughout the
