Distances with type Ia Supernovae / Blue Team / Pre-recorded

• Isobel Hook

State of the art of the field. What are the best data and methods ? How do the error bars are measured ? What are the measurements ? What are the claims ? What are the claimed limitations ?

Distances with type Ia Supernovae / Red Team forms and prepares constructive criticism

• Bruno Leibundgut

What the the limitations of the methods ? What could be hidden systematics ? Are there better methods to apply ? Is there any new astrophysical effect that may affect the measurement ?

Distances with type Ia Supernovae / Red Team presents

• Dan Scolnic

Take home message. What would it take to convince the red team that the blue team is doing the correct thing and that what it claims it does is actually done ?

Distances with type Ia Supernovae / White team to form and present consensus Find consensus and propose concrete tests to improve measurements and address criticism by blue team. Design guardrails to avoid unconscious bias.

Establishing guardrails - ALL teams Based on state-of-the-art (blue team) and criticisms be red team, find a protocole to follow to mitigate at least some of the main drawbacks of Supernova distances, if not all.
