What Happened When Earth Lost 90% of Its Magnetic Field? | Documentary For Sleep

Описание: Tonight on Just About Earth, we’re exploring a moment when our planet’s invisible shield nearly disappeared. What happened when Earth lost 90% of its magnetic field? Without its protection, radiation surged, auroras spread across the skies, and the planet’s surface changed in ways we’re only beginning to understand. In this gentle documentary for sleep, we drift through the science and mystery of that fragile time — when Earth stood almost unguarded beneath the sun.

This video is part of a peaceful space for science to fall asleep to — soft documentaries for sleep and calming science facts to rest with. If your mind finds calm in quiet stories of change and resilience, you’re in the right place.

Where are you watching from tonight — and what time is it there? I love reading your check-ins. They feel like small beacons glowing across the map, like auroras of their own.

If this helped ease your thoughts or gave your imagination something vast to wander through, feel free to like, subscribe, or simply close your eyes — knowing that even when Earth’s defenses falter, life always finds a way to endure.

Wishing you stillness,
beneath the quiet shimmer of a weakened sky.
