"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...
In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally ...
The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
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 ...
Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...
Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

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 ...
