This work of theoretical Physics is related to current gravitational theories (superstrings). It is well-known that a work about the unification of the main four interactions of Nature is being developed at the present, in which gravitational force does not fit in unification outlines, and which have allowed the unification of nuclear forces with electromagnetic forces. It is particularly deepened the work about the geometric aspect of these theories, not previously studied in a suitable way. The new geometries proposed by the authors, allow reaching new results that explain appropriately some particularities of the astrophysical observations, such as supernovas radiation and cosmic bottom radiation.

The results of these researches are published in important magazines of theoretical physics, such as Physical Review D. On the other hand, in a recent event carried out in the United States about Cosmology, the works of Quiros and collaborators were mentioned by the organizers, as important contribution to physical theories that explain the behavior of universe. The quality of the author's achievements has made that he is considered a reviser of prestigious magazines.

It is important to highlight the merit of this small group of authors, which in the Central University of Las Villas have achieved these outstanding results in this complex and exclusive subject as Physics of the Whole, useful to explain the behavior of the universe where we live.
