(PhysOrg.com) -- The rule that nothing can travel faster than the speed of light, c, is one of the most fundamental laws of nature. But since this speed limit has only been experimentally demonstrated for information carried ...
In physics, as in life, it's always good to look at things from different perspectives.

(PhysOrg.com) -- Police and military forces around the world may soon have a new non-lethal weapon at their hands. Called the Thunder Generator, the device is a cannon that fires shock waves that pass through people and objects. ...
A team of researchers from several European countries and one from Chile has found evidence of three possibly habitable exoplanets circling the star GJ1061. In their paper uploaded to the arXiv preprint server, and soon to ...
(Phys.org) -- In Isaac Newton's Principia Mathematica published in 1687, the man many consider the most brilliant mathematician of all time used a mathematical formula to describe the path taken by an object when it is thrown ...
(PhysOrg.com) -- A team of scientists from France have worked out why teapots dribble at low flow rates, and how to stop them. The effect is called the "teapot effect", and solving it could finally put an end to tea stains ...
Researchers from the FOM Institute AMOLF and the University of Pennsylvania have fabricated a material which gives visible light a nearly infinite wavelength. The new metamaterial is made by stacking silver and silicon nitride ...

Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating ...
(PhysOrg.com) -- When a meteor impacts a planet or a moon, it always stops at a relatively shallow depth, even when impacting at high speeds. Until now, researchers have assumed that all objects impacting a granular medium ...
