Scientists Build Microscopic Engine Producing Heat Equivalent to 13 Million Degrees Celsius Without Combustion
In a remarkable experiment that redefines the limits of thermodynamics, scientists have created a microscopic engine capable of reaching an effective temperature of 13 million degrees Celsius—hotter than the Sun’s core, yet without producing any actual heat. The device consists of a single glass bead only 5 micrometres wide, suspended in an electric field inside a vacuum chamber. By shaking the bead’s energy through an oscillating voltage, researchers made it move so violently that its kinetic energy mimicked temperatures that would otherwise vaporize any known material. Despite the staggering “heat,” the bead itself remained at room temperature, offering a new perspective on how motion and energy interplay at the quantum and microscale levels. Devamını Oku
