Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Can you please explain to us how awesome this is, and what you hope the ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

Imagine you want to study what happens when an object accelerates. Oh, this is way before any of that internet stuff—also, no computers or electronics. In fact, let's say it's the year 1780. What do ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

An artist's impression of the quantum experiment. (Courtesy: University of Southampton) The first technique capable of measuring the pull of gravity on a particle just microns in diameter could aid ...
