While we remain busy down here on Earth, the threat of world-ending asteroids and meteorites looms over the planet. It is widely believed that a 10-kilometer-wide asteroid that passed through our atmosphere and splash-landed in the Gulf of Mexico caused the extinction of the dinosaurs 65 million years ago. Nothing prevents a well-aimed meteorite or wandering asteroids from dooming human life to the same fate. Depending on where one would land, these giant space rocks could cause massive tsunamis, widespread conflagration, or government-toppling social unrest. Without highly sensitive scientific equipment, regular folks will have no idea if asteroids or meteorites are headed their way until a glowing orange ball of fire appears in the sky. And let’s not forget that one of these could have been en route to our corner of the solar system for thousands of years. What’s not to worry about? Out of sight, out of mind. But are we already out of time?
