A couple of years ago, in a fairly rural area of Siberia, a “small” asteroid “grazed” the Earth’s surface with the equivalent force of 300,000 tons of TNT. Three thousand buildings were damaged, and more than 1,000 people were injured (thankfully, none of them fatally).
Now, imagine if that asteroid had struck in the middle of Chicago. Or Boston. Or New York. Buildings would have been leveled. Millions would have died. That’s a real — though slim — possibility, every single day. If you’re anywhere near where the asteroid lands, you could burn to death or even be vaporized. A medium-sized asteroid striking NYC, according to one expert, would be the equivalent of 10 nuclear bombs striking at once.
