A star known as S0-2 (the blue and green object in this artist’s rendering) made its closest approach to the supermassive black hole at the center of the Milky Way in 2018. (Nicole Fuller / National ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

Astronomers have identified a potential ultra-fast pulsar spinning every 8.19 milliseconds close to Sagittarius A*, the supermassive black hole at the center of the Milky Way. If confirmed, this ...

According to Einstein's theory of general relativity, gravity results from how mass warps space and time. The greater an object's mass, the stronger its gravitational pull. Scientists have largely ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...
