Wait, ho do you catch a
"sonic boom of light?" While we are asking questions, what is the difference between a mach cone and a photonic mach cone?
Just as aircraft flying at supersonic speeds create cone-shaped sonic booms, pulses of light can leave behind cone-shaped wakes of light. Now, a superfast camera has captured the first-ever video of these events. The new technology used to make this discovery could one day allow scientists to help watch neurons fire and image live activity in the brain, researchers say.
