Light passes through our eyes and hits on the retina. Photo cells in the retina releases electro chemical signals which are sent to the brain and behold! a picture is created from the electrochemical signals which are pieced together by the brain into a picture.
This really fascinates me sometimes. We're in actual fact watching a reality movie, so high is the resolution and quality of this movie (btw it even has 3D!) that we think we're living in it!
Does this fact teases your mind as it does mine?
