> We would immediately build better telescopes to track it precisely, refine its trajectory models, and begin developing propulsion systems capable of interception

That's not what would happen. We wouldn't mobilize. We'd fragment. Within days, the prediction would be declared partisan. One bloc would call it settled science; another would call it statistical hysteria. Billionaires would quietly commission private shelters while publicly funding studies questioning whether the asteroid even qualified as "large." News panels would debate whether the projected impact zone was being unfairly politicized. Conspiracy channels would insist the asteroid was fabricated to justify global governance. Others would insist the real asteroid was being hidden. Amateur analysts would flood the internet with homemade trajectory charts proving the professionals wrong. Death threats would arrive in astronomers' inboxes faster than research grants.
