Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping. For over a ...

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, ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

Introduced to the world in 1915, Einstein's general theory of relativity radically changed the Newtonian model of gravity. General relativity introduced the concept of mass warping the very fabric of ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

Carlo Rovelli is a physicist at Aix–Marseille University, Marseille, France, and an associate member of the Rotman Institute of Philosophy in London, Ontario, Canada. Nature seems to have played us ...

Santa Claus is not breaking the law. He is just using Einstein's physics to bend the rules of time and deliver presents to ...
