The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

Einstein's theory of general relativity, published in 1916, built upon his earlier work, including special relativity and the mass-energy equivalence, both published in his "Annus Mirabilis" in 1905.

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the physicist ...

Scientists are using observations of black holes to test the limits of general relativity, aiming to identify potential inconsistencies or incompleteness in Einstein's theory. Multiple methods are ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

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 ...
