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 ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

There are few scientific concepts that are as famous as Albert Einstein's theory of general relativity, but even the iconic theory isn't set in stone. Einstein's theory of general relativity states ...

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 ...

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 ...

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 ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

Most current models of the Big Bang rely on general relativity along with additional elements that are introduced to make the ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...
