Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace its path backward through time rather than…
By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird part-solid, part-liquid-like state thought to exist inside Earth’s inner core is indeed possible.
This year, the number of NASA-tracked confirmed worlds discovered beyond our solar system surpassed 6,000, and several thousand more await confirmation.
