  11. we go any further, it's important to get a clear idea of what time reversal symmetry really means. At the simplest level, we may think of the laws of physics as equations involving a time variable , and say that they are symmetric under time reversal if given any solution, and making the substitution , we obtain another solution. http://math.ucr.edu/home/baez/time/time.html What does t (and - t) stand for in physics ? only time ?
  12. I understand, that is, this principle says that if an event exists that could give rise to a paradox, then the probability of that event happening is zero.. Is it logic ?
