I know it's an old movie now, and prob everyone's been to this link, but for those who haven't it's an interesting experience. http://www.philosophers.co.uk/games/matrix.htm Actually, we may be living in a kind of matrix. The Universe may be a hologram. Serch 'holographic theory of the universe' sometime. The fundamental structure of the Universe, whatever it may be, creates our 'Reality'. Our 'Reality' is a projection produced by some more fundamental source, invisible to us. The hardness of the table your monitor and keyboard sits on is due not to the atoms it's made of, but is due to the invisible electromagnetic force between the atoms. This force, that we cannot experience in any way, except for its percieved effects, is more 'real' than our experience of its consequences.
