I'm not a physicist, but I believe the current understanding is that there's no 15 billion years ago. Time is a side-effect of measuring entropy, and according to the Big Bang theory you go backwards in spacetime to a point of infinite density and temperature, and there's no "past" that.
- effie 6y agoTime is most definitely not a side effect of measuring entropy. Time elapsed is defined by number of periods of some (natural or artificial) periodic phenomenon. Orbiting of the Sun, or pendulum swinging, or clock hands motion, or electric circuit current oscillations. None of these periodic processes have anything to do with the concept of entropy.
