In the last century, physicists have revealed a complex world of fundamental particles.
Brian Metzger, an astrophysicist at the Flatiron Institute's Center for Computational Astrophysics, weighs in on a series of recent studies that describe a giant flare erupting from a magnetar — a neutron star with an outlandishly intense magnetic field.
Creating Bose-Einstein condensates — and crashing them together — in microgravity could lead to physics breakthroughs, better spacecraft navigation and more.
Physicists aim to make practical materials that conduct electricity with zero resistance
László Lovász of Eötvös Loránd University in Budapest and Avi Wigderson of the Institute for Advanced Study in Princeton, N.J. will share this year’s Abel Prize — regarded as the field’s equivalent of the Nobel — for advances in understanding the foundations of what can and cannot be solved with computers.
The Atacama Large Millimeter/submillimeter Array (ALMA), a set of 66 radio astronomy dishes perched high in the Chilean Andes, shut down on last March and has remained silent ever since. But ALMA managers announced that observations will resume this month, after a 6-month campaign of repairs and planning.
A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of that gold sphere tugging on another similarly sized sphere confirm that gravity behaves as expected even for extremely weak gravitational fields.
