“Demystifying Black Holes”
Gia Dvali (LMU-MPI, Munich)
Abstract: Black holes are considered to be one of the most mysterious objects of nature due to their properties such as the information horizon, absence of hair, thermal evolution and information storage and processing. We argue that these properties are not specific to gravity but are generic to a large class of objects, called “saturons”, that exhibit a maximal microstate degeneracy. The role of saturons is played by solitons and various other bound states in ordinary field theories, including QCD. They exist also in non-relativistic many-body systems and can potentially be studied in labs. This view opens up a very different perspective on black hole physics, allowing its understanding in terms of the universal phenomenon of saturation. It also suggests a link with seemingly remote phenomena, such as confinement in QCD, and provides some new observational prospects.
