Solar Flares & Coronal Mass Ejections - Defending Earth from Our Own Star

Oct 5, 2025 Megastructures & Extreme Engineering
Solar storms are inevitable; disaster isn’t. We explore the physics of flares and CMEs, historical extremes, and realistic defenses—detection, delay, and planetary-scale shielding—to weather the Sun’s worst days.
