The Planck Era & Inflation: Foundations

The Planck era refers to an extremely early regime where quantum effects of gravity are expected to be essential and current theories are incomplete. Inflation connects high-energy physics to CMB anisotropies, structure formation, and searches for primordial gravitational-wave signatures.

Rapid inflation can stretch a small causally connected region to scales larger than the observable universe, flatten spatial curvature, dilute unwanted relics, and magnify microscopic quantum fluctuations into seeds for later structure.
