Modern fundamental physics contains ideas just as revolutionary as those of Copernicus or Newton; ideas that may radically change our understanding of the world; ideas such as extra dimensions of space, or the possible existence of other Universes.
Testing these concepts requires enormous energies, far higher than what is achievable by the Large Hadron Collider at CERN, and in fact, beyond any conceivable Earth-bound experiments. However, at the Big Bang, the Universe itself performed the ultimate experiment and left clues and evidence about what was behind the origin of the cosmos as we know it, and how it is evolving. And the biggest clue is the afterglow of the Big Bang itself. In the past decade we have been able to answer age-old questions accurately, such as how old the Universe is, what it contains, and its destiny.
Along with these answers have also come many exciting new questions. Hiranya Peiris will unravel the detective story, explaining what we have uncovered, and how we know what we know.
There will be cake and coffee from 3 pm, the lecture starts at 3.15 pm.
The Rosseland lecturer 2017 is Professor Hiranya Peiris, Director of the Oskar Klein Centre for Cosmoparticle Physics in Stockholm, Professor of Astrophysics at University College London and Vice-President of the Royal Astronomical Society.
Peiris is currently a member of the Planck Collaboration, a satelite mission from the European Space Agency that has mapped the primordial fluctuations of the cosmic microwave radiation in the universe with exquisite precision. She is also a member of the ongoing Dark Energy Survey (DES), the Dark Energy Spectroscopic Instrument (DESI, starting in 2018), and the Large Synoptic Survey Telescope (LSST, currently under construction), which are all next generation galaxy surveys that will yield deep insights into the evolution of the Universe and its underlying physics.
The Rosseland Lecture
The Rosseland Lecture is held annually by the Institute of Theoretical Astrophysics, University of Oslo, in memory of Norway’s foremost astrophysicist, and founder of our institute, Professor Svein Rosseland (1894 – 1985). The Rosseland Lecturers are internationally renowned, outstanding astrophysicists. The Rosseland Lectures hold a semi-popular level and are open for all.
