Two extreme processes are presented: the formation of black holes and the origin of the universe. How does the physical concept of singularity explain the two phenomena?
Mariafelicia De Laurentis is a researcher in the Naples section of the National Institute of Nuclear Physics (INFN) and Professor of Astronomy and Astrophysics at the "Federico II" University of Naples. She is among the protagonists of the research that led to the first image of a black hole, through the international projects Black Hole Cam (BHCam) and Event Horizon Telescope (EHT). She taught in Russia and Germany. Her scientific activity is centered on theories of gravitation in their theoretical and phenomenological aspects, to which she has devoted numerous articles for international journals. We report the following publications in English: Invariance Principles and Extended Gravity: Theory and Probes (with S. Capozziello, New York 2011) and General Relativity and Cosmology: A Primer (with S. Capozziello, Berlin-London 2018).
Massimo Pietroni teaches astroparticle physics at the University of Parma. He worked at the DESY laboratories in Hamburg, at CERN in Geneva and at the National Institute of Nuclear Physics in Padua. He conducts research at the turn of particle physics and cosmology, convinced that the universe is the most precious laboratory of fundamental physics at our disposal. In particular, he would like to understand more about the nature of dark matter and dark energy, and how these two mysterious entities have influenced the history of the universe. He has written numerous publications in international journals.
