These observations have led them to believe that it is made up of an as yet unknown substance. Sabine Hossenfelder is a physicist and science writer. She is currently a research fellow at the Frankfurt Institute for Advanced Studies. Sabine's research focuses on the foundations of physics. But her interests extend to the philosophy and sociology of science. Sabine partly works as science writer. Her writing has been published, among others, in Scientific American, New Scientist, Nautilus, Aeon, and the New York Times. Sabine has an active YouTube Channel dedicated to communicating current science news and scientific methods in general. This talk was recorded on 10 June 2021.
