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 ...
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 ...
Einstein showed that gravity and motion warp time. Now, that idea is being put to the test on Mars - where understanding how seconds drift could one day shape how humans live and communicate beyond ...
The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...
Time moves faster on Mars than on Earth. Physicists have confirmed this effect, crucial for future space missions. Even tiny ...
The European Space Agency (ESA) is getting ready for the launch of an atomic clock system that aims to validate elements of Einstein’s theory of general relativity but could have implications for more ...
Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications ...
The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...
An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...
