Historically, Earth’s North and South magnetic poles have flipped every 200,000 or 300,000 years—except right now, they haven’t flipped successfully for about 780,000 years. But the planet’s magnetic field is at long last showing signs of shifting. Although there’s no way to know yet for sure, it could be gearing up to flip once more, according to Undark Magazine. And that possibility is raising new speculation about what that means for planetary life.
