The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach... more

The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. Physicists therefore discuss whether... more

Two spacecraft confirm that time passes more slowly closer to Earth’s surface. more

The botched launch of two global-positioning satellites four years ago has proven to be a real gift to physicists. more

In 2016, an international team of scientists found definitive evidence—tiny ripples in space known as gravitational waves—to support one of the last remaining untested predictions of Einstein's theory of general... more

Europe’s Galileo satellite navigation system – already serving users globally – has now provided a historic... more

Albert Einstein is famous for a lot of reasons, but the movement of sediments in rivers is perhaps not one of them. Yet, his name is associated with those of Ackers, White, and Shields... more

Europe's Galileo satellite navigation system – already serving users globally – has now provided a historic service to the physics community worldwide, enabling the most accurate measurement ever... more

Einstein's 'God Letter' is seen as a key statement in the debate between science and religion. more

Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with... more

The famous 1954 letter lays out the physicist's thoughts on the existence of a supreme being. more

The dynamic properties of liquid phase-change materials (PCMs), such as viscosity and the atomic self-diffusion coefficient D, play an essential... more

Once again, a decades-old theory of gravity has survived a modern scientific onslaught. Einstein wins again. more

The path of light is bent by mass, an effect predicted by Einstein's theory of gravity, and when a massive galaxy or cluster lies along our line-of-sight to a more distant galaxy its matter will act as a lens to... more

For the first time astronomers have detected gravitational waves from a merged, hyper-massive neutron star. The scientists, Maurice van Putten... more
