25th February 2021 – London Cosmology Discussion Meeting

For this UCL-organized Meeting we asked two speakers, Prof. Alan Heavens (Imperial – slides) and Prof. John Ellis (King’s), to each give us a thought-provoking summary of perspectives on how to break the standard model of cosmology (from the Astrophysics and HEP viewpoints, respectively) in the next 10-20 years. Each talk was followed by 10 minutes of small-group discussion in randomly assigned breakout rooms, and the session drew to a close with a 10-minute full-group discussion. In this discussion, the group was asked two questions: “What is more likely to break LCDM (Astro or HEP)?” and “What’s your best bet on what will break it?”. The answers to these surveys can be found below, along with slides for the two talks.
