Lecture: "The Missing Universe"

On Friday evening January 10, 2025 from 20.00 to 22.00 Prof. Dr. Auke-Pieter Colijn (University of Amsterdam) will give a lecture : The Missing Universe. The lecture is in Het Groene Huis in Amersfoort and is organized by Sterrenwacht Midden Nederland.
At all distance scales, the dynamics of our universe can only be explained if we assume that a large amount of new matter is added. Despite the fact that for every kilo of ordinary matter - that is, atoms and molecules - there must be about five kilos of new matter, this matter has never been directly observed. Dark matter, in other words. I am trained as a particle physicist, so I suspect that this dark matter consists of new particles that have never been observed until now. This story is about the search for these new particles with extremely sensitive measuring equipment in an underground laboratory in Italy.

Prof. Dr. Auke-Pieter Colijn says the following:
I am a professor of experimental astroparticle physics at the University of Amsterdam. Until 2015, I worked on collision experiments at the Fermilab in Chicago and at CERN in Geneva. The equipment I worked on for the ATLAS experiment at CERN was used for the discovery of the Higgs particle, for which the Nobel Prize in Physics was awarded in 2013.
Since 2011, I have been more concerned with the particles that reach Earth from the universe: astro-particle physics, in other words. I am working on an experiment to discover so-called dark matter. My home base is the University of Amsterdam and the Dutch Institute for Subatomic Physics (Nikhef), but my experiment is built in the underground Gran Sasso laboratory in Italy.
