On a June morning in 1908, something fell from the sky above the remote Siberian taiga and remade the world's understanding of its own vulnerability. The Tunguska event—still the largest impact in recorded human history—flattened 830 square miles of forest without leaving a crater, a paradox that took decades to unravel and a century to still not fully resolve.

The question is not merely academic: it is the

No direct consumer impact. Indirectly, continued scientific interest may support funding for asteroid detection systems that could benefit long-term planetary safety and insurance markets.
May reinforce policy arguments for increased funding in planetary defense initiatives, asteroid detection networks, and space monitoring infrastructure. Could influence insurance and disaster preparedness regulations related to low-probability, high-impact events.
