DFG research group on particle physics illuminates philosophical and historical aspects in a workshop at RWTH Aachen University

Astrophysical observations and explanatory gaps in the standard model of particle physics imply the existence of dark matter or an alternative theory of space and time. Dark matter is a postulated form of matter that is not directly visible, but interacts via gravity. "According to current theories, 80 percent of the matter in the universe should consist of dark matter," explains Professor Michael Krämer from the Chair for Theoretical Physics E at RWTH. “The search for this new form of matter has so far been unsuccessful, so physicists are looking for alternative explanations. A modified theory of gravity could possibly describe the movement of galaxies. It remains to be seen whether dark matter and a modified theory of spacetime are two different sides of the same coin, ”said Krämer.

The Aachen physicist works in the research group "The Epistemology of the Large Hadron Collider". This has been funded by the German Research Foundation (DFG) and the Austrian Fund for the Promotion of Scientific Research (FWF) with around 2.5 million euros since 2016. More than 20 international scientists from the fields of physics, philosophy, the history and sociology of science discuss the understanding of scientific knowledge in particle physics. Professor Gregor Schiemann from the Interdisciplinary Center for Science and Technology Research at the Bergische Universität Wuppertal is the spokesman for the research group. “The dialogue between physics and philosophy has not received enough attention for a long time. We are successfully counteracting this with our interdisciplinary cooperation, ”says Schiemann.

The DFG research group is organizing a workshop on “Dark Matter and Alternative Gravity” from February 6th to 8th, 2019 at RWTH Aachen University. Around 70 international participants are expected, who particularly want to shed light on the philosophical and historical aspects of this central debate in modern basic research.
