On December 14-th, 2016, professor Sabino Matarrese of the University of Padova will hold for a VIS project a Public Cosmology Conference in the Sala Azzurra, at 5:30 pm. Free admission. Following refreshments in the Grand Prior Hall. Here below the details of the conference.
What happened during the first second after the Big Bang?
In the early 1980s many cosmologists and theoretical physicists come independently to the same conclusion: the universe, during its very first moment of life, went through an accelerated expansion phase. The American physicist Alan Guth named this phase “inflation” a paroxysmal process of “swelling”, from which originated all that we observe today in the outer space. All matter, in its variety of forms, the whole complex structure that we observe in the universe, in the form of galaxies, clusters of galaxies, and more. All this would have originated from little tiny “seeds” generated by the quantum vacuum during the inflation. This process of generation “from the void” has been actually suggested already in the 1930s by one of the fathers of quantum mechanics, Erwin Schrödinger. Frightened by his revolutionary intuition, he described this process as an “alarming phenomenon”. It is thanks to this “alarming phenomenon” that today the cosmologists can explain, with astonishing accuracy, a wide variety of cosmological observations. The cosmic inflation theory seems to not leave space for opponents!
The evolution of the inflationary theory has marked my entire scientific life. Both through the contribution I have been trying to bring in order to develop this idea, and the long and diligent data analysis work as a part of the Planck collaboration of the European Space Agency.
Sabino Matarrese is a full professor in Cosmology at the University of Padua. He also worked at the SISSA in Trieste and at the MPA in Garching, Germany. He is the author of more than 370 publications on the most prestigious and important international journals of physics and astrophysics. He is also the editor of a book about the dark components of the Universe. His research interests range from the cosmology of the primordial Universe (the inflation theory, in particular) to the analysis of the cosmic microwave background. He is also interested in the study of the dark components of the Universe, in the formation of structures and in the formation of gravitational waves in the cosmos. He is a member of the National Institutes of Physics and Astrophysics. Lately, he has been affiliated to the Gran Sasso Science Institute.
He collaborates with the European Space Agency for the Planck mission, to study the cosmic microwave background. He is also engaged in the preparation of the future missions Euclid, to study the dark components of the Universe, and LISA, to search for gravitational waves.
