Yann Mambrini is CNRS (The French National Center of Scientific Research) research director in theoretical physics and a member of the CNRS scientific council. Author of more than 100 scientific articles in peer-reviewed international journals, he is passionate about time, its nature and its extent, especially the primordial universe that has been his research topic for over 15 years.
He is also member of the scientific committee of the Theoretical Physics Laboratory at the University of Paris-Saclay and an associate researcher at CERN. He is a member of the board of directors of the Department of Planetary and Universe Science (SPU) at the University of Paris-Saclay, a professor at the doctoral school of the École Polytechnique and École Normale Supérieure, a member of the scientific committee of more than five international conferences and a three-time winner. CNRS scientific excellence for its research work (2010, 2014 and 2018) and the French Society of Physics Award 2006.
SEEING THE INVISIBLE UNIVERSE
We now know that our universe is made up of dark energy and dark matter. Far from destabilizing us, this observation urges us to ask ourselves a fundamental question: what does visible mean? What does "observe" mean? Since the advent of quantum physics and Heisenberg's uncertainty principle, we know that observing a particle means observing the consequences of its interaction on the environment. We perform experimental measurements, collect computerized data that we translate or interpret as physical phenomena. Then how do we deduce from what we are made of?
The very nature of space-time, invisible, is nevertheless determined by precise equations that Einstein imagined more than a century ago: another invisible, more formal one. In this intervention, we aim to show that, by combining the mathematical and observational invisible, we manage to resume the history of the Universe from its origins to the present day. Our history will intersect with dark matter, neutrinos, string theory, and additional dimensions. We will present a complete overview of the state of our knowledge on this invisible world that surrounds and structures us.
