When is a theory good enough?

Series
The Physics of Fine-Tuning
Embed
In the third part of their discussion, Pedro Ferreira and Jerome Martin talk about whether one should look for a deeper physical theory when one’s current theory is well-supported by observation.
They discuss the rise of inflationary theory, its alternatives, and our expectations for future physics. This discussion was conducted at the University of Oxford on March 15, 2017.

Can we measure naturalness?

Series
The Physics of Fine-Tuning
Embed
In the second part of their discussion, Pedro Ferreira and Jerome Martin consider ways to build the naturalness of an inflationary model into our expectations for observing it.
They debate the feasibility of measuring the degree to which an inflationary model is inspired by considerations from other parts of physics, and describe the applicability of Bayesian methods when we have background knowledge. This discussion was conducted at the University of Oxford on March 15, 2017.

Strings, Inflation, and Alternatives

Series
The Physics of Fine-Tuning
Embed
In the third part of their discussion, Dave Sloan and Robert Brandenberger explain the relationship between string theory and inflationary models. Can inflation arise from particle physics, or do we need to look for alternative models?
This discussion was conducted at the University of Oxford on March 14, 2017.

Panel on Inflation

Series
The Physics of Fine-Tuning
Embed
Professor Joe Silk talks with Professor Robert Brandenberger, Professor Jerome Martin, and Dr. Dave Sloan about the current state of research and controversies surrounding inflation.
They discuss the possibility of connecting inflation to string theory and the likelihood of the initial conditions required by inflationary models. This lecture was conducted at the Dennis Sciama Theatre at the Denys Wilkinson Building, Oxford, on March 14, 2016.
