Description
Comet nuclei might be unlikely to hit Earth—but that’s not the real danger. As Randall Carlson explains, when a comet breaks apart, it can create a debris stream stretching millions of miles. If Earth’s orbit intersects that stream, the odds of impacts rise dramatically—like flying through an asteroid field, except Earth can’t maneuver out of the way. This short explores the last-decade realization: statistical risk changes once disintegration turns one nucleus into countless Tunguska-sized fragments.
