A new study shows that the movie's idea of blowing up the asteroid is way off

If Bruce Willis' ability to destroy life-threatening asteroids put your mind at ease about the end of the world, here's a study to bring you back to reality.  
 
Michael Bay's 1998 hit movie Armageddon depicted Bruce Willis and a team of oil drilling heroes setting off nuclear bombs on an asteroid that was rushing toward Earth, thus saving all of humanity from the end of the world -- aka Armageddon. 
 
A class of physics students from the University of Leicester in the UK decided to look into whether this kind of scenario would ever be possible. The short answer is no, but they provided some evidence as to why. 
 
To debunk this mystery, the class first gathered basic information about the asteroid itself (which were mentioned in the film), such as the total volume of the asteroid pieces, the clearance radius (radius of Earth plus 400 miles), its distance from Earth at detonation, the asteroid's pre-detonation velocity, and the density of the asteroid pieces. 
 

Harry Stamper is not amused
 
Using this information, they created a formula to find the total amount of kinetic energy needed to blow the asteroid to smithereens. As it turns out, 800 trillion terajoules of energy would be needed to break the asteroid into two pieces, allowing it to bypass planet Earth. This means that any bomb used would have to be a billion times stronger than any bomb ever detonated on Earth.
 
FYI -- the largest bomb ever detonated on Earth was the Soviet Union's "Big Ivan," which was a 50 megaton hydrogen bomb that only had an energy output of 418,000 terajoules. 
 
From there, issues arose with the time needed to detect the asteroid in order to be able to successfully blow it up. It would need to explode at the point in which it is detected at 8 billion miles. 
 
"A series of assumptions must be made due to limited information in the film," said the class paper titled, 'Could Bruce Willis Save the World?' "First, the asteroid is approximated as a spherical object 1000km in diameter (the asteroid is quoted being the size of Texas) that splits into two equal-sized hemispheres. The asteroid in the film reaches a clearance either side of the Earth of 400 miles (640km) which is the assumed value for our calculation."

I'm from New Orleans, which pretty much has a tradition for crooked Governors. Trust me, money has been given to New Orleans for levy improvements for decades and decades before Katrina.

Now what that money actually went to, well, I'll let you figure that out. However a project was underway years before Katrina to upgrade the Ninth Ward floodwall, one that gave way after a runaway barge collided with it and caused flooding. Guess what? Residents complaining about the noise sued to have the project stopped! DOH! Good going. If it was fully upgraded it might have held.

As you can imagine, Katrina is a sore subject for me. Seeing your hometown almost destroyed is bad enough. Watching it become a political chew toy and seeing it used by the media and the Democrats to somehow blame the President before the bodies were even cold...unacceptable.

So no offense, but when I see some jackass make some Bush-bashing comment about Katrina, it's not appreciated. Katrina would have played out exactly the same, no matter who was in office.

Here are more facts about what actually happened to cause the flooding. Not the usual media spin. Katrina was a systematic failure of the local and state bureaucracy.

Sorry for offending you in such a personal way. My intent was to show exactly what you also said :

So would Armageddon (which was my point in my op). So would a lot of other things (we got Osama! etc). Whoever is in office gets to take the praise or persecution of whatever happens regardless of their involvement. What truly goes on is the works of a great many people behind the scenes and out of the media spotlight. So bashing specific Dems or Reps is silly, as these days almost all politicians are crooked and no good.
