FUNDAMENTAL FORCES IN THE UNIVERSE

FUNDAMENTAL FORCES IN THE UNIVERSE

We can see a huge variety of events in nature, since the fall of a leaf in autumn to a supernova explosion. It may seem that there is a great disparity of origins and explanations to understand so many phenomena and as diverse as those that occur in the universe. However, it is accepted by scientists that everything can be described simply from four fundamental forces.

Fundamental forces are those forces of the universe that cannot be explained on the basis of other more basic. Four are known so far fundamental interactions or forces: gravitational, electromagnetic and nuclear strong and nuclear weak.

*The gravity is the force of attraction that a piece of matter exerts over another, and it affects all bodies. Gravity is a very weak force and an only sense, but of infinite reach. It’s the weaker but it affects all matter. According to current theories, the force of gravity is generated due to the interaction of the graviton. They are particles which have not yet been detected, but it is believed that they are responsible for transmitting the force of gravity.

*The electromagnetic force affects the electrically charged bodies, and is the force involved in the physical and chemical transformations of atoms and molecules. It is much more intense than the gravitational force, has two senses (positive and negative) and its scope is infinite. particles of our body are held together by the electromagnetic force.

*Force or strong nuclear interaction is that holds together the components of atomic nuclei, and works interchangeably between two nucleons any, protons or neutrons. Its range is on the order of the nuclear dimensions, but it is more intense than the electromagnetic force. Suppose that all matter is composed of atoms, and that these atoms are mainly composed of protons (have positive charge) and neutrons (don't load). In addition, these protons and neutrons are composed of smaller particles called quarks. To keep the quarks in the nucleus of atoms, there is the strong nuclear force. This force is more powerful than the electromagnetic, but its scope is much smaller.

*Force or weak nuclear interaction is responsible for the neutron beta decay; neutrinos are only sensitive to this type of interaction. Its intensity is less than the electromagnetic force and its scope is even lower than the strong nuclear interaction. Interact, certain particle Exchange bosons, and these bosons transmit the weak nuclear force. This force allows particles to interact to exchange energy, mass, electric charge and "flavor" (already explain this later).

My conclusion is that the fact that everything can be explained from them does not mean that it is actually carried out. In the first place because there is no yet a unified theory encompassing the four forces, and secondly because, even if you have it, if it is that physicists give to it, perhaps the
