What happens if a city-flattening asteroid is spotted just two weeks before impact? Kurzgesagt takes us through every wild idea scientists have considered: painting space rocks, blasting them with nukes, even pulling off a Hollywood-style Armageddon mission, and why most of them won’t work.
But there’s hope: new “cosmic bullets” made of tungsten could actually pulverize an asteroid into harmless fireworks instead of global doom. And if we ever get the cosmic middle finger from a true planet-killer? Well… buckle up, because it’s gonna take the wildest, most expensive one-way field trip humanity’s ever booked.
