From the big bang to the empty end – the universe from the point of view of modern cosmology
The scientific view point on our Universe has gone through a major transformation in the last decades. In my talk, I will talk about the knows but also the major unknowns we have. My main focus will be on the observations that lead to our current understanding.

Simon Birrer is a Postdoctoral Researcher at the University of California, Los Angeles (UCLA) in the department of Physics and Astronomy. Before joining UCLA, he received his PhD from ETH Zurich in the cosmology research group. Birrer’s research focus on the mysteries of dark matter and dark energy. He is an expert in using strong gravitational lensing, the bending in space-time that lead to strong distortions and multiple appearance of the same source, to probe fundamental physics questions on cosmological scales. Birrer works in the interface between the exquisite data sets available on one side and the fundamental theory predictions on the other side.
