Astrid Eichhorn What is the Fundamental Microscopic Structure of Space-Time in our Universe?

Dr. Astrid Eichhorn works at the Institute for Theoretical Physics at Heidelberg University where she leads a research group as part of the DFG’s (Deutsche Forschungsgemeinschaft) Emmy Noether Programme. She is a Visiting Fellow at Canada’s Perimeter Institute for Theoretical Physics and has held a Junior Research Fellowship at Imperial College London. Her research interests include asymptotically safe quantum gravity and matter and Renormalization Group flows in discrete models of quantum space-time. In April 2018 she was appointed as a new member of the Junge Akademie.

What are the building blocks of our universe that everything is made of? In this video, ASTRID EICHHORN explains how her work seeks to reveal the fundamental microscopic structure of space-time. While recent pioneering experiments have confirmed aspects of Einstein’s General Theory of Relativity, this work seeks to overcome the limitations of current observational technology through theoretical investigations of the relationships between quantum space-time, quantum gravity and matter. With undoubted implications for our understanding of Dark Matter and the Standard Model of particle physics, the real-world applications of this kind of foundational research can have profound effects on all of our lives.
