Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

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 ...

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 ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

A pair of professors fr0m North Carolina State University are proposing an entirely new model of physics that could rewrite the way we think about matter. Their extremely ambitious proposal, as ...

For the past two decades, astronomers have been testing Einstein’s general theory of relativity using an exquisite celestial laboratory located thousands of light-years away, in the direction of the ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

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 ...
