What if Earth had no magnetic field?

Imagine a world where compasses spin aimlessly, auroras vanish, and our planet stands defenseless against the sun's wrath. This isn't science fiction—it's a chilling reality we'd face if Earth lost its magnetic field. Our invisible shield, born from the planet's molten core, protects us from cosmic radiation and solar winds. Without it, life as we know it would be under siege. From communication blackouts to DNA damage, the consequences would be far-reaching and potentially catastrophic. But what exactly would happen? How quickly would our world change? And could humanity find a way to survive in this new, unprotected Earth? Brace yourself as we dive into the fascinating and terrifying possibilities of a world without our magnetic guardian.
