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…

In the Universe, there should be as much matter as antimatter. As soon as particles and antiparticles collide, they annihilate each other and what remains is energy. However, since we obviously live in a Universe with matter - there are stars,…
