Physicists at the University of Arizona have achieved a significant breakthrough in imaging the subatomic world. They have developed the world’s fastest electron microscope, capable of capturing events that last just one attosecond — a quintillionth of a second. These cutting-edge instruments are vital for studying ultrafast processes. An “attomicroscope” operates on a scale that dwarfs even the fastest cameras. Essentially, it freezes time to observe events at the particle level, including moving electrons. An attosecond is a staggeringly brief moment — there are as many attoseconds in a sing…
