Lecture series & guided tour „Understanding the Universe“


Lecture series on the experiments at the world’s largest particle accelerator

On the Polyterrasse at ETH Zurich, the exhibition „The Code of the Universe“ offers a visually stunning insight into particle physics and research at CERN until 15 October. In addition, between 20 September and 11 October 2023, four public lectures will explore the clarified and unclarified questions of the universe and give a broad audience an in-depth insight into the experiments at the world’s largest particle accelerator.

Find out how the collisions of the smallest particles can be made visible, why the findings of the experiments are also important for your everyday life and what questions the researchers are working on. Let yourself be infected by the enthusiasm of the lecturers and ask them questions.


11 October, 18.30 hrs 
ETH Zürich, Rämistrasse 101, 8092 Zürich, Hörsaal HG E3:
The riddle of antimatter
Dr. Katharina Müller, Head of Particle Physics, University of Zurich

The event is held in German.

If matter and antimatter actually annihilate each other, why could the universe come into being? It is still not understood why matter and antimatter did not completely annihilate each other shortly after the Big Bang and why we live in a universe dominated by matter. Among other things, this question is being investigated in experiments at CERN. In this lecture, you will learn what exactly antimatter is, why its understanding is so important and how researchers are trying to find answers to their questions.

On the lecture days, young researchers will also guide visitors through the exhibition „The Code of the Universe“. Participation free of charge and without registration, from 5.45 p.m. to approx. 6.15 p.m. each day. Meeting point: directly at the exhibition, Polyterrasse
