To make sense of this we need to understand how physicists probe the smallest scales of nature. And that means understanding the physics of scattering. Every time you open your eyes, you are performing a scattering experiment. Photons from some light source like the S_ bounce - or scatter off objects in the world around you into your particle detectors-aka your eyes. Your analysis computer-aka your brain-then builds up a color map of the world around you based on the properties of those p_
