Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum ...

For nearly a century, scientists around the world have been searching for dark matter—an invisible substance believed to make ...

Scientists have used a portable “atomic clock” to measure gravity for the first time. The device makes use of small changes in the flow of time at different altitudes to measure the Earth’s ...

Our New Atomic Clock Is So Precise That We Need a Better Understanding of Gravity To Use It Our measurements of gravity are not good enough for NIST's new atomic clock. By Avery Thompson Published ...

More French pendulum clock from the French region of Franch-Comte. ... Many subsequent refinements, even prior to Newton's gravity, were made to this original design. Christian Huygens, 1658.

Famously, gravity and quantum mechanics do not mix and represent a giant gap between our understanding of the macro world of humans and the quantum-governed micro world of particles.

If we ignore this but still assume there is Newtonian gravity, the key driver would be where the centre of mass of this Earth was. The gravitational force on the flat surface would act towards ...
