Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

A new study takes the opposite tack – Professor Jonathan Oppenheim from University College London (UCL) proposes that spacetime follows classical physics after all, and instead it’s quantum theory ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a ...
