Björn Malte Schäfer Can General Relativity Explain the Properties of Gravity on Very Large Scales?
Gravity is the decisive force driving the formation and evolution of cosmic structures. BJÖRN MALTE SCHÄFER is interested in the properties of gravity on very large scales as well as in very specific questions concerning structure formation, such as how galaxies acquire their angular momentum, how they start rotating, and how galaxies interact with surrounding structures. Currently, the understanding of gravity is based on general relativity. As is explained in this video, the research group tried to investigate the properties of gravity by making observations on very large scales, i.e. they look at the formation and evolution of structures in the universe, namely galaxies. Applying this method, they have found good evidence to further support the idea of general relativity as the theory of gravity on large scales. This allows to make specific predictions for future surveys and future experiments.
