The shapes of the space
Tuesday October 20th, 2009 , h.20,30Geometry: what does it study today? What do researchers in mathematics do? Are there really new things to be discovered? Why do we talk about different geometries? Do shapes imagined by mathematicians have a connection with ones studied in theoretical physics?
Space in physics is a dinamic and measurable entity. It can expand itself, it can trasform itself into time and it is curved because of the presence of matter and energy. In order to investigate it at small distances we need powerful "microscopes" like LHC. In order to unify grafity and quantum mechanics physicists made the hypothesis that the fundamental entities are strings. In this case, universe should have six more dimensions not yet observed.
