But when light slows down, sometimes matter can blaze past that speed limit, creating a stunning glow called Cherenkov radiation. We can see this glow in a nuclear reactor as high-energy particles speed by. It offers us a window into a realm of the universe that is usually invisible to us.Filmed at the J. J.
