STRING THEORY-AN OVERVIEW

The string theory was always a very interesting subject. It captured the attention of many science reporters and SF movie producers. This part of physics is meant to discover some patterns in the universe that go beyond the atomic and subatomic particles that we can't study and understand.

All the elementary particles in the Universe are made of some strings that are under a continuous tension. Although our Universe is composed of four dimensions (up-down, front-behind, right-left and time), the strings are moving under 11 dimensions (the M theory). But the other seven left are imperceptible to us.

We can see the atoms, protons and electrons but we cannot see the strings and their vibration. String theory also contains other objects than strings, called membranes. It is said that our Universe is on a membrane which is infinite in length but very thin. The result of the collision between a membrane that contains our Universe and other that contains a parallel universe consisted in the Big Bang.

String theory is a pure mathematical hypothesis. We cannot even prove that these strings exist. The scientists tried to predict the energy interactions made by them and even the gravitational problems emitted by Einstein. Afterwards, they associated everything with a stable approach of quantum mechanics.

Quantum mechanics or quantum physics is a modern branch of physics that studies the behavior of atomic and subatomic particles. The founders of quantum mechanics were Max Plank, Erwin Schrodinger and Werner Von Heisenberg. The research on this matter was developed between 1926 and 1935.

However, the string theory is not widely accepted by all physicians. Many consider that this "theory of everything" is completely wrong. Thousands of pages were written about it, hundreds of debates took place but not a single testable event was performed, nor a prediction was solved. In their point of view, the string theory is just an untested mathematical thought rather than a real theory. Two partizan's of these ideas are Lee Smolin, the founder of the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, and Columbia University mathematician Peter Woit. They both have written books regarding the inefficiency of the string theory.
