A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

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 ...

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 ...

Susskind, a physics professor at Stanford, and Cabannas, a former MIT math professor, offer an overview of Einstein’s theory of general relativity in this survey for specialists, the fourth volume of ...
