Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks. A phenomenon of ...

For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum mechanics, which govern the smallest particles, fit with the laws of ...

JILA physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...

Add Yahoo as a preferred source to see more of our stories on Google. The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in ...

Ever since Albert Einstein published his general theory of relativity in a series of landmark papers in November 1915, it has fascinated generations of scientists and the scientifically interested ...

Every smartphone navigation fix, every precision agriculture pass, and every aircraft approach depends on atomic clocks ...

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 ...
