I sit in math class everyday and wonder what would happen if I were to send my pencil, which has been sitting still on my desk for sometime now, back in time so that my future pencil occupies the same space as my past pencil. Obviously this is a paradox because if the pencils annihilate each other then the past pencil won't exist to destroy itself after traveling back in time. Each time I ask myself this question I come to the same conclusion, it's many worlds rule or universal consistency. What thoughts do you have?(adsbygoogle = window.adsbygoogle || []).push({});
