Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. Finding such an unmasked form of what physicists term a singularity "would shock the foundation of general relativity." picked by AutumnLotus 2 years ago

Falling into a black hole might not be good for your health, but at least the view would be fine. A new simulation shows what you might see on your way towards the black hole's crushing central singularity. The research could help physicists understand the apparently paradoxical fate of matter and energy in a black hole. picked by AutumnLotus 8 months ago

A widely circulated photograph shows an Air Force Raptor 22 jet breaking the fabled sound barrier while performing aerial maneuvers in the Gulf of Alaska.

The phenomenon is not well studied. Scientists refer to it as a vapor cone, shock collar, or shock egg, and it's thought to be created by what's called a Prandtl-Glauert singularity. picked by Bingo 5 months ago

IT IS the ultimate cosmic villain: space and time come to an abrupt end in its presence and the laws of physics break down. Now it seems a "naked" black hole may yet emerge in our universe, after spinning away its event horizon. picked by AutumnLotus 4 months ago

"Jurisprudence of Artilects: Blueprint for a Synthetic Citizen" by Frank W. Sudia, JD., a member of the American Bar Association's Section of Science and Technology Law, tries to get the laws ready for synthetic citizens BEFORE they exist. picked by michelleroberts 3 years ago

IBM has demonstrated the ability to store a bit on a single atom, as well as a molecular switch that could enable processors small enough to create dust-speck-sized supercomputers.
