Time is like a wheel. The wheel that keeps moving forward until the end of time. The wheel is nobody can turn back. Maybe, the time is the only essence that free from the world's rule. It is because time is one of the rules of the world. The rules are able to bind all elements and all living creature in the world.

Time flows. It said that time started when the big bang took event. From that time, time grow side by side with the world, the universe. Time grows with the ever-expanding galaxies. Time is following every event that took place in the world.
