Document Summary
Brain is a change detector we like variation about something that is constant. Low light to dark light in visual system (unique to humans) Generate sensitivity to change over time as the world changes and we change to react to stimulus therefore deterring change is important. The mechanisms that evolved to help us understand what we see make slight variations as to what is actually there at the present time. Most likely as it understood after it has been physically seen and detected by receptors. Seeing something else that is not really there. If every place is relative, then every motion is relative. Motion cannot be understood without a determination of its direction which in its turn cannot be understood except in relation to some other body. Therefore if we supposed everything is annihilated except one globe, it would impossible. You cannot keep a single point low light source in a completely dark environment still as.
