Russia has quietly taken a bold step toward solving one of spaceflight’s oldest problems by patenting a space station design ...

Based on Einstein's theory, they demonstrated that if a massive object rotates rapidly, it drags space-time along with it.

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

Russia, which is preparing to independently launch a space station in 2027, was recently reported to have newly designed a ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
