Scott travels to Medjugorje, Bosnia to investigate reports of sun miracles, witnesses one himself with his wife, and develops a naturalistic explanation involving afterimages and atmospheric conditions that explains both the Medjugorje and Fatima phenomena. Longer summary

Scott Alexander investigates the sun miracle at Medjugorje, Bosnia, where thousands of pilgrims report seeing the sun spin and change colors. He travels there with his wife, interviews locals, and witnesses a small-scale miracle himself. After analyzing the experience and comparing it to the famous Fatima miracle, he proposes a naturalistic explanation involving afterimages, eye damage, and specific cloud conditions. The post explores eyewitness accounts, the history of Marian apparitions at Medjugorje, and the optical physics behind the phenomenon, ultimately concluding that while impressive, the miracle can be explained through unusual but natural atmospheric conditions combined with prolonged sun-gazing.
