According to theoretical physics, nothing is faster than the speed of light. However, now you can see with your own eyes the first ever recording of a “sonic boom” – created by light. Or scientifically called a photonic Mach cone. It was recorded by researchers at Washington University in St. Louis, and they used a custom high-speed camera to make the footage.
You’ve heard about sonic booms, and you’ve probably heard one at least once. They occur when an object exceeds the speed of sound. But if nothing is theoretically faster than light – how did they do this? In the description, the setting seems simple, and they built the custom high-speed camera – the fastest one in the world.
