A group of German physicists at TU Dresden has tested two proposed means of propellantless propulsion – the EmDrive and Mach Effect Thrusters – and found the act of testing is what makes these arguably physics-flouting technologies appear to work.
Time feels real to people. But it doesn’t even exist, according to quantum physics. "There is no time variable in the fundamental equations that describe the world," theoretical physicist Carlo Rovelli tells Quartz. If you met him socially, Rovelli wouldn't assault you with abstractions and math to prove this point. He'd "rather not ruin a...
John Preskill is a theoretical physicist and the Richard P. Feynman Professor of Theoretical Physics at Caltech. In this episode we cover what John’s been focusing on for years: quantum information, quantum computing, and quantum error correction.
Scientists use nanotube films and polarized light to strongly couple light and matter progressively and on demand at room temperature. Their technique could help scientists who study data storage and the manipulation of light at quantum levels.
Yale physicists have uncovered hints of a time crystal — a form of matter that “ticks” when exposed to an electromagnetic pulse — in the last place they expected: a crystal you might find in a child’s toy.
