More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole ...

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm ...

Earth’s rotation has been measured many times over — but never like this. In a first, scientists used entangled quantum particles called photons to reveal the rate at which the globe spins. The feat ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...
