Erik Curiel and Simon Friederich discuss how reasoning in cosmology sometimes conflates topological stability with probability, and why that might be wrong.
In the second part of their discussion, Erik Curiel and Simon Friederich talk about the connection between stability arguments, which are popular in discussions of fine-tuning, and probability. Erik raises a problem for a common form of reasoning in cosmology. This discussion was conducted at the University of Oxford on October 6, 2017.
