The origin and a force

Noberto Molina Olivera 

Electromagnetism, weak nuclear interaction, strong nuclear interaction and gravitational force, are the four fundamental forces that govern our universe. These are responsible of many of the phenomenon’s observed in everyday life. Simple things like gravity, is what keep us on the ground, to the more complex like the nuclear interactions that go to the atomic level. These are very important and capable of great things but can it be possible that these forces were once a single force?

The idea of a single force comes from physics theories that try to understand the nature of it but to see the possibility of a force, it is necessary to go back to the origin of everything; the big bang. The explosion that started it all and that expanded a small region into the huge universe that we see today. At this point there were two distinct conditions, extreme high temperature and density, concentrated in a region of space. Here is where the theory of everything can be applied. This theory is a standard model that explains the possibility of a single force, the combination of the four fundamentals. It says that at the extreme conditions of high energy and density the forces tend to become one. The only problem with it is that gravity can’t be added to the mix, with a mathematical model that follows the knowledge of today’s physics.

Although the combination of the four forces it has not been proven experimentally, it does not means that it is impossible. Interactions like electricity and magnetism were once thought of different concepts but after years of work and study James Maxwell was capable to demonstrate that they had a connection, that they were one. Furthermore, the weak nuclear interaction tends to become one with electromagnetism as the energy raises.

Going back to the beginning of time when the combined force existed, the big bang occurred the force started to break, to discompose. First, gravity separated and left behind electronuclear force. As the universe cooled down the electronuclear force also started to decompose into the other three fundamental forces. Thus the four forces of nature were created and their particular functions came into place.

It is very interesting to understand how the universe and the forces started. Although today’s knowledge is very limited and there is very little experimental prove  but the possibilities are present. To prove these theories is to understand the very core of force and it is a step closer to reach the full understanding of the origin of the universe.
