Which of Massimo Porrati's research interests is about the fate of the universe?
Massimo Porrati Massimo Porrati (born 1961 in Genova, Italy) is a professor of physics, and a member of the Center for Cosmology and Particle Physics, at New York University. He graduated from the Scuola Normale Superiore di Pisa, Italy with a "Diploma di Scienze" degree in 1985. Later he worked as a postdoctoral fellow at UCLA and UC Berkeley in the USA. He was a research scientist at the INFN section in Pisa, Italy, in collaboration with CERN, where he over the years has spent several periods, before joining NYU in 1992. His major research interests are String Theory, Supersymmetry and Supergravity, Nonperturbative Aspects of Strings and Quantum Field Theory, and Cosmology.
Age of the universe In physical cosmology, the age of the universe is the time elapsed since the Big Bang. The current measurement of the age of the universe is billion (10) years within the Lambda-CDM concordance model. The uncertainty has been narrowed down to 21 million years, based on a number of projects that all give extremely close figures for the age. These include studies of the microwave background radiation, and measurements by the Planck satellite, the Wilkinson Microwave Anisotropy Probe and other probes. Measurements of the cosmic background radiation give the cooling time of the universe since the Big Bang, and measurements of the expansion rate of the universe can be used to calculate its approximate age by extrapolating backwards in time.
