Are you sure about that?
I’m fairly sure that measuring departure and arrival time with a light beam over a short distance of only 3 feet is plenty of room for error. Like I said, how can something arrive before it leaves?
Like I said earlier, if they truly broke the speed of light then the light arrived before it even left the point of origin. Totally impossible.
The speed of sound was broken, not by sound, but by something we propelled faster than sound.
