Event description

For more than 80 years, astrophysicists have collected data that suggests 80% of matter in the universe is 'dark'. These observations have led them to believe that it is made up of an as yet unknown substance.

In this talk Sabine Hossenfelder will explore the evidence for and against the existence of 'dark' matter. She will argue that that the best explanation is a suitable combination of dark matter and a modification of general relativity, which can be realized by the idea that dark matter has a superfluid phase.
