(PhysOrg.com) -- Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the observer’s role in measurements, ...
Researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam found that hidden dimensions – as predicted by string theory – could influence gravitational waves. In a recently ...

(Phys.org)—Recent gravitational wave detections have allowed physicists to confirm with greater and greater precision what Einstein predicted over 100 years ago in the theory of general relativity: that gravity does not ...
(Phys.org)—According to the best current physics models, the universe should have collapsed shortly after inflation—the period that lasted for a fraction of a second immediately after the Big Bang.
Aircraft turbulence guidelines should be completely rewritten after new research by Centre of Excellence chief investigator Dr. Todd Lane revealed thunderstorms could produce unexpected turbulence more than 100km away from ...

A trio of physicists with Columbia University is making waves with a new theory about phonons—they suggest they might have negative mass, and because of that, have negative gravity. Angelo Esposito, Rafael Krichevsky and ...
The ongoing volcanic eruption in Tonga began in December 2021, but it wasn't until 5:15pm local time on January 15 2022 that the powerful explosion occurred. It generated an enormous cloud of ash, earthquakes, and tsunamis ...
