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 ...

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 ...

Aligarh, Dec. 29 -- day National Workshop titled"Introductory Workshop on General Relativity and Gravitation (IWGRG-2025)". Organized in collaboration with IUCAA, Pune, and supported by ANRF and CSIR.

Dark energy, making up 70% of the universe, causes its accelerating expansion. Gravitational waves, predicted by Einstein, were detected from colliding black holes. The Event Horizon Telescope imaged ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, ...

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 ...
