Is Alice’s rabbit made of antimatter? 

Besides being an intriguing, philosophical and recurring theme in science-fiction films, what do we know about antimatter today? In particular, what does it tell us about the notion of time? 

In this talk, we’ll take you back in time to the Big Bang, the creation of matter and antimatter. 

Thanks to discrete symmetries, physics offers us a mathematical framework for linking and describing the differences between matter and antimatter.  

We’d like to provide some insight into the question: “Why has antimatter disappeared from our Universe?” This then raises the question of how we can study what has disappeared. 

CERN’s experiments enable us to make antimatter, allowing us to explore its properties and unravel its mysteries. We’ll choose examples from the myriads of experimental techniques to illustrate how scientists are tackling this topic.
