"Breakthrough: Capturing Sound Waves Inside Diamond Crystal"

TL;DR
Scientists have successfully observed sound waves moving through a diamond crystal using a novel X-ray method. By employing an X-ray microscope, the researchers were able to visualize acoustic waves within mm-sized crystals with subpicosecond precision, allowing them to study the creation, propagation, branching, and energy dissipation of longitudinal and transverse acoustic waves in a diamond. This breakthrough could lead to rapid imaging of various solid objects, such as metals, ceramics, rocks, and bones.
