A team of researchers at the International Center for Relativistic Astrophysics has found evidence that suggests Sagittarius A* is not a massive black hole but is instead a mass of dark matter. In their paper published in ...
(Phys.org) -- Renewable energy technologies generally consist of two distinct processes: energy generation (using sources such as coal, solar, wind, etc.) and energy storage (such as batteries). These two processes are always ...
(Phys.org) —Relativity and quantum theory form the backbone of modern physics, but a group of physicists stresses that daily use of these theories can numb the sense of wonder at their immense empirical success. At the ...
When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
(Phys.org)—Decision-making—the ability to choose one path out of several options—is generally considered a cognitive ability possessed by biological systems, but not by physical objects. Now in a new study, researchers ...
A Swiss company called Rinspeed has recently announced its newest project: an underwater car. Named "sQuba," the car can both drive on roads, and then - at the push of a button - dive up to 10 meters (33 feet) under the sea.
NASA's Mars helicopter Ingenuity has suffered a sensor failure, according to Håvard Grip, the chief helicopter pilot on the project. In a recent blog post on the NASA Science page, he described some of the challenges the ...
The complex patterns of the natural world often turn out to be governed by relatively simple mathematical relationships. A seashell grows at a rate proportional to its size, resulting in a delicate spiral. The gossamer network ...
(PhysOrg.com) -- In 1998, scientists discovered that the Universe is expanding at an accelerating rate. Currently, the most widely accepted explanation for this observation is the presence of an unidentified dark energy, ...
(PhysOrg.com) -- Researchers have designed a toothbrush that cleans teeth by creating a solar-powered chemical reaction in the mouth, doing away with the need for toothpaste.
