Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

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 ...

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, ...

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 ...
