Dark matter is one of the greatest mysteries of modern physics. We can measure exactly how it attracts normal, visible matter, but still we have no idea what it is made of. Black holes? New types of particles? Researchers in the MADMAX collaboration want to track down such an unusual particle using an innovative experimental setup.
In this edition of Café & Kosmos, Dr. Johannes Diehl from the Max Planck Institute for Physics explains why the team needs a giant magnet and sapphire plates for their search, what a detergent has to do with all of this and what brand new measurements have revealed.
