Einstein's theory of relativity is in large part a simple statement that the Universe has a speed limit (the speed of light), and all the complex and amazing facts that entails. If they Universe doesn't have a speed limit after all, how is that everywhere we look there appears to be a speed limit, except in certain corners? How does the speed limit not hold in non-local action, and what prevents non-local action from making every thing else avoid the speed limit?
