Before the pitchforks come out in the comments, yes, we all know quite well that Armageddon is just a movie and that Michael Bay cares as much about scientific accuracy as he does, well, anything that isn't an explosion. But speaking of explosions, a class at the University of Leicester in the U.K. has set their brilliant minds to cracking one of the greatest questions of our age: Could Bruce Willis really have blown up the asteroid in Armageddon?
The obvious answer is yes, yes he could. He's Bruce Willis and he can do whatever the hell he wants.
The scientific answer, however, is a little less entertaining. Yes, nukes redirecting asteroids is conceivable, but going off of the asteroid's parameters as stated in the movie, Willis would need 800 trillion terajoules of energy to split the asteroid in half. The trouble there is that the biggest bomb ever detonated on Earth was a pathetic 418,000 terajoules (watch the Tsar Bomb's asteroid-impotent show of force below). Yes, sadly enough, for as self-destructive we are as a species, we've surprisingly never built a bomb powerful enough to destroy the hypothetical asteroid in Armageddon.
The human race has failed you, Bruce Willis.
