Inflation in the very early Universe and the goal to detect the large-scale B-mode pattern originating from primordial gravitational waves, a key signature of inflation. Single-field slow-roll inflation produces nearly scale-invariant perturbations. Explore the landscape of super-Planckian scenarios.
