Please explain the edge of the Universe
I recently read about Michael Berry's calculations of the effects of initial conditions on chaotic systems in a book that I returned to the library so I don't have any references. He calculated that removing a single electron from the far edge of the universe 10^10 light years away is enough to alter the configuration of air molecules in a lung sized closed vessel in only 100 milliseconds. Obviously it would have needed to have been removed 10^10 years ago. What is the far edge of the Universe?
