Journal 9/21 continued

In a completely dark room we wouldnt be able to see anything. There wouldnt be any light rays to bounce off of anything to go back to our eyes. Nothing would be visible even though our eyes would be much more sensitive to light. Our classroom wasnt completely dark otherwise we wouldnt be able to see anything at all. For a room to be completely dark, no light rays can enter the room. We couldnt totally seal off the room and make sure no light comes in.
