Something is rotten in the state of cosmology. To be, or not to be, that is the question: Do we require an extension of L-CDM and if so which form should it take? We meet on a Danish castle to discuss these existential questions in cosmology.

Scope

The Hubble tension has risen to become one of cosmology’s most hotly debated topics. It calls for new physics in the early Universe at energy scales that can be probed with observations of the cosmic microwave background. However, despite the fact that the tension has been  debated for close to a decade, there is only a small handful of interesting theoretical resolutions that offer both a solid micropyhsical  justification and a viable phenomenology. The aim of the wH0rksH0p is simple: Discuss the status of these existing solutions and find new ways forward.
