In a first, US-based researchers have filmed light creating a ‘sonic boom’ – officially known as a photonic Mach cone – using a new ultra-speed camera capable of taking 100 billion frames in a second. The real-time video shows light pulses leaving behind cone-shaped wakes of light, just like aircrafts flying at speeds faster than sound, creating sonic booms.
