"For the time being, this is the only violation of special relativity that I know of,...

(Newser) - Two Scottish physics professors have published a report on forces of attraction that could be used to make objects levitate, writes the Telegraph. They've engineered a way to reverse the Casimir force, which normally causes elements to stick together. The discovery may lead to frictionless levitating parts in small mechanical...

(Newser) - Researchers are reporting the biggest stellar explosion ever recorded—a discovery which could shed light on how the universe was shaped. The star, 150 times more massive than the sun, went out with a bang 100 times more powerful than typical supernovas. Astronomers think the first stars after the Big...
