Hold a pen, and wobble it, and it seems like the pen bends. This is a very simple bending of the light scientists would say, but they are wrong, and this is why:
The world is only as real as our perception of it. Therefore, since we perceive the pen to bend, it does. This may go against all laws of physics and science, but it does.
Many people have disagreed with this theory, however, those people were proved wrong when one man jumped of the top of an extremely tall building with his eyes closed. He survived the incident because he did not perceive the ground that he should have landed on, and was therefore unharmed.
Since then, no other people have disputed this theory, and no one has had the guts to repeat the experiment.
WARNING: DO NOT REPEAT THE EXPERIMENT!
