Kai Schmitz’s field of work lies at the interface of particle physics and cosmology; his favourite subject is gravitational waves from the early universe. In an interview with Christina Hoppenbrock, the research group leader at the Institute of Theoretical Physics provides insights into the evolution of the universe, methods of research and still unresolved questions about cosmology.

I’d like to talk to you about evolution, but not about evolution in the Darwinian sense...

The term evolution is also very common in cosmology. ...
