A geomagnetic reversal involves a significant weakening and flipping of Earth's magnetic field, historically occurring every 200,000 to 300,000 years. The last full reversal was about 780,000 years ago, with scientists suggesting we may be overdue for another. If this reversal happened unexpectedly, especially in urban environments like New York City, compasses would be disrupted and navigational systems would fail, leading to widespread panic as societal infrastructure crumbled. Although pole reversals generally take thousands of years, some theorists speculate that a swift change could trigger immediate chaos.
A geomagnetic reversal happens when Earth's magnetic field weakens, becomes unstable, and flips. These events have occurred roughly every 200,000 to 300,000 years throughout Earth's history.
The last full reversal happened about 780,000 years ago. Some scientists argue we may be overdue.
In New York City, if a sudden geomagnetic reversal occurred, compasses would become unreliable, global systems would break down, and there would be widespread panic.
While pole reversals usually happen over thousands of years, conspiracy theorists believe a sudden flip could trigger chaos within days or weeks.
