Time is aman made idea caused by the rise and setting of the sun. We have proven an atomic clock runs slower when energy (speed) is applied to it. However the change is not as significant as exspected because Einstein suggested an object will get smaller when energy is applied. Our G.P.S. sattelites must have their clocks changed every day for these anomolies.
The Universe did not worry about time until man arrived. Before him everything was a constant.
