Guanajuato, Gto., December 27, 2016.- The Universe could not be made of dots such as electrons or quarks, but it could be the consequence of vibrations emitted by small strings that join and shape all the objects not only in three but nine dimensions.

This is one of the most debated affirmations in current Physics, also known as String Theory. This has defined the research of several professors at the University of Guanajuato (UG), such as Dr. Oscar Gerardo Loaiza Brito, of the Division of Sciences and Engineering.

The head of the Department of Physics explained that today, one of the greatest enigmas is gravity, since Albert Einstein's Theory of Relativity exists, which defines at a macroscopic level, it still is incompatible with the theories that analyze it at a microscopic level, such as the Quantum Field Theory that describes very well other forces of the nature.

However, the String Theory has the potential to describe gravity in a quantic way. This theory, assumes the material particles apparently punctual are really "vibrational states" of a basic extended object called string.

According this proposal, an electron is not a "dot" without internal structure and zero dimension, but a gathering of minuscule strings that vibrate in a space-time of nine dimensions.

Now, he commented, a string can do more than move: it can oscillate in different ways. If it oscillates in a way, then, microscopically we would see an electron; but if it oscillates in another way, then we would see a photon, or a quark, or any other particle of the standard model.

So, if the string theory is not only one, since it is in continuous construction, its proposal would allow to comprehend gravity as a vibration, which will open the possibility of understanding other fundamental questions such as the origin of the universe or answer questions such as: why does the universe expands? What determined its origin? Do black holes really exist? And if so, what happens inside and around them?

"In the same way as a guitar, strings tangle, break and vibrate; it seems that their notes establish the music where the own universe is born, grows and dances until its death", he exemplified.

Dr. Oscar Gerardo Loaiza Brito added that there are around two thousand researchers in foreign institutions, that work around the string theory, hence in Mexico the number is smaller. However, he assured that the University of Guanajuato has gathered a strong group of researchers such as Dr. Gustavo Niz Quevedo, Dr. Oscar Miguel Sabido Moreno and Dr. Nana Geraldine Cabo Bizet, same that have generated projects where they incorporate students from high school, master's and Ph.D.

Likewise, he pointed out that the University has a tight relation with groups from the Universidad Autónoma de México (UNAM), the Centro de Investigación y de Estudios Avanzados (Cinvestav) and the University of Colima (UdeC), as well as European universities, so they offer a strong formation in the study of Universe.
