The Gravitation

The Gravitation

Many physics laws rule the universe, like gravitation, law of action and reaction, law of Hooke, Coulomb’s law and other laws. Scientist until today try explain a lot of laws but no one knows. They just know the effects of physical laws. Physics laws mean that it always happen; it is a constant. People usually do not knows the difference between theory and laws. Theory is the idea attempt to prove something, and it proves this through facts, events, and phenomena. However, theories cannot become  a law until it has been proven continuously . If someone proves an exception in any theory, it cannot become a law. If it occurred once, it can happen more times. Today we have several theories that try to explain physics laws but most of the physics laws do not have explanation.

The first law of Newton says,  “Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed”. If something is moving, then it should continue moving until another force interacts with it. The first Newton law is similar to the law of gravitation. Gravitation is a constant that keep everything in the center of the mass. It can explain why you cannot fly if you jump or why your cell phone drops to the floor. Also it can explain why things did not move from one place to another, unless through interaction with another force. Why does it happen? Today no one can explain it. Several theories to try explain it. I believe that the theory of gravitons has the best logic about gravitation; this theory explain that there are many gravitons pushing everything to the center of the mass. If everything has a center of mass, then everything is pushing everything.

  Many explanations has been proposed. According to Dmitrii Blokhintsev and F. M. Gal'perin in 1934 the gravitons is an elementary particle that push everything to center of the mass. However, this  theory contradicts the theory of Le Sage's that says infinite particles will always drop to the floor aiming for the center of any object . Many scientists do not believe in this theory, and it was dismissed. Since it has not been proven incorrect, this theory is still valid. Also exist scientists that still believing and working on this theory.

  The history most famous about gravitation is about Newton, and the apple tree. While sitting under an apple tree, an apple dropped on his head and he asked, "why"? Then he studied and created the law of universal gravitation. He proved that this law explains the perfect equilibrium in the universe. It can explain the reasons why the planets do not collide, and why the satellites do not get out of orbit. It is commonly thought that Newton was the first to study gravitating, but that is not true. According to J J O'Connor and E F Robertson, the old Greeks tried to explain it in 310 A.C., Aristotle was one of the many people who tried to explain it using different theories that made full sense.  Newton used the knowledge of Aristotle to create the article called “Philosophiae naturalis principia mathematica” which explains, the rules of the universe. Newton had the great idea to join the other theories and created the law of universal gravitation.

  Today we have the knowledge to go to moon and to know about other planets and stars. We can forecast about meteors that aimed for Earth.  Today people can create incredible technology to do almost everything that we want. However,  we cannot explain why my cell phone dropped to the floor and shattered the screen. Something simple that has baffled minds since the beginning of time still cannot be explained. We wasted more than two hundred years trying explain something elementary and until today we cannot explain. For these reasons and other, I believe in God. The world is very perfect to be created by nothing. Everything is very perfect to us live.
