Attractors, Universality and Inflation

Understand

Studies of the initial conditions for inflation have conflicting predictions from exponential suppression to inevitability.

• At the level of phase space, this conflict arises from the competing intuitions of CPT invariance and thermodynamics.
• After reviewing this conflict, we enlarge the ensemble beyond phase space to include scalar potential data.
• We show how this leads to an important contribution from inflection point inflation, enhancing the likelihood of inflation to an inverse cubic power law.
