This is the first time that disk-jet co-precession has been clearly observed in a black hole system, which is truly exciting, ...

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

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

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 ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

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 ...

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 ...
