"Dark" doesn't actually exist. Photons reflect off a surface and bounce back, hitting you right in the eyeball at literally the speed of light. Where there are no photons, there's nothing to reflect back to the observer, thus the subject is "dark". The sheer force of these impacts has no effect whatsoever, as photons have no mass. Your eyes take a relentless pounding all day long, and those waves-and/or-particles are converted into electrical signals that you interpret to be the thing you are looking at.
Your reality is entirely unique, because your brain doesn't work exactly the same way as anyone else's. Real life is fuckin crazy.
