so there's a guy name steve .. now steve is paid a lot of money to keep exact time.. now did you know that if a space shit circles the earth for 10 years , a thousand years has gone by on earth. They have found you could hold a worm hole open by using negative energy. You could allso use a cosmic string and visit your own past. No matter which way you figure it we arnt able to do it today. But if a person shows up telling you they are your grate grate grate grand daughter don't push them away.
There are certen people in todays world who don't use time at all. They go by life as the moon and sun circle the earth.
