"April 1, 2004�Man has struggled throughout time with proving that what exists in his mind also exists in the world outside his mind. When the
idea relates to a physical object or a law of motion, the proof might be difficult, but still possible. Man was able to prove that the world is not
flat, for example, and with time could even prove that the sun is at the center of the solar system and that it is possible to split an atom. These
ideas existed in man's mind before they were proven, and the proof came because the physical world allowed man the opportunity to test his
hypothesis."
