Physicists from the University of Colorado have created an atomic clock so precise it can measure gravitational time dilation over distances as small as one millimeter. This record-breaking ...

Another possible explanation for dark matter is that its effects are caused by fields that vary in strength over time, which in turn lead to regular fluctuations in the strength of the electromagnetic ...

Scientists at the University of Oxford recently published the results of a mind-blowing experiment wherein they entangled two atomic clocks at a record-breaking distance of two meters. Up front: ...

Sending an atomic clock onboard a spacecraft to fly close to the sun might be the trick to uncovering the nature of dark matter, suggests a new study published in Nature Astronomy. Dark matter makes ...
