The essence of universe


Universe, totally is the existence filled of all the matters and energies. In this case, we can say that matter and energy are the essence of the universe.
Let's seperate the essence into two parts, matter and energy.
The matter in the universe is a subject to various of forces. Matters are exist in the universe, such as stars. When the matter trying to be active, they are making some forces. These are the energies in the universe. In these forces, the most effective and the biggest force is gravitation, which pulls all matters together to be a system. In addition, the reactions will be continuing until the star has consumed all its acailable nuclear fuel.
In the universe, there should be some systems, such as solar system. There is a theory was published that earth is the center of the universe. But after that, this theory was reversed by Coperinicus in 16th centry. He thought that sun should be the center of the universe, and this theory has been demonstrated. In this case, as universe is a whole system, we can consider that this is a system which surrounding the sun. It is a big system that we can not count how many matters in it.
Universe is a place that filled with mysterious. We are still on our way to know much more about it. As the technology developed so quickly, we have to believe, we will open the door which is an obstacle for us to discover the universe.
Human beings, go ahead !
