Speaker/s

The beginnings of the XXI century brought the development of the standard model of cosmology. The Universe is made of a 70% of dark energy, a 25% of dark matters and a 5% of ordinary matter. Even with a dark sector that still needs to be studied, this theory has had a brilliant success in the explanation of the cosmos. However, some new results obtained in the last few years could imply a new paradigm change. Some incompatible measurements of the expansion rate of the Universe and its smoothness place the standard model in tension. In this talk I will present a review of the new cosmology and the dark sector of the Universe, and of the tensions it faces and their possible consequences in our understanding of the cosmos.
