Last week Mads Frandsen gave a public talk arranged by The Danish Youth Association of Science – UNF-Odense.
Today we know, that we can only see 4% of the universe. This is the bright side of the universe consisting of the known elementary particles. But there is also a “dark side” consisting of “dark matter” and dark energy, which we cannot see and measure directly, but it constitutes more than 5 times as much of the universe. Among other things, dark matter is necessary to explain some the the largest structures we observe in the universe. It is still an open question what dark matter is made of.
In the talk Mads Frandsen will explain how we can be sure that dark matter exists, what its role is in the universe, and what it may consist of at the level of elementary particles.
