Reproducible demonstration of the look-elsewhere effect in CMB anomaly searches, via Penrose's Hawking points. Pure Gaussian skies routinely produce 4-5 sigma 'anomalies' once you scan position and scale; the same test still confirms a real signal. A companion script reproduces the Jow & Scott (2020) null result on real Planck data.
