According to quantum theory, particles do not have a definite state, e.g. in terms of their spin, polarization or flavour (color) - only relative probabilities. Only when a measurement is carried out does the particle “decide” on a state.

On April 28 and 29, 2025 a meeting of the German particle physics community will take place at the Max Planck Institute for Physics. The workshop is part of the decision-making process for the long-term European strategy in particle physics. The…

The Max Planck Institute for Physics (MPP) proudly congratulates the ATLAS Collaboration at CERN on receiving the Breakthrough Prize in Fundamental Physics. Scientists from the institute are among the thousands of researchers worldwide honored with…

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,…

The eROSITA satellite observes the entire sky in the X-ray range. Developed and built at the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching, it was launched from the Baikonur Cosmodrome on July 13, 2019, and has carried out a…

Cells are the smallest units that we can undoubtedly recognise as alive. The membrane, a complex mixture of lipids and proteins, plays a central role in this because it separates the inside of the cell from the outside world. To form membranes, all…

The Senate of the Max Planck Society has appointed the renowned theoretical particle physicist Gavin Salam, professor at the University of Oxford, as an External Scientific Member at the Max Planck Institute for Physics (MPP). Scientists in MPP’s…
