Summary
It is shown the connection between torsion, which is a necessary geometrical feature of the space-time when gravity is considered in the realm of elementary-particle physics as, for instance, in the early universe, and some property of string theory. We emphasize also the role of torsion when one tries to quantize the gravitational field, that is to quantize the space-time itself. Finally it is shown that through the time-temperature uncertainty relation it is possible to arrive at the notion of a minimum acceleration that can be important in connection with observations involving galaxies.
