Comments on: Meteor warning system needed, says panel

Strikes are rare, but the results could be cataclysmic; an early detection system could prevent such impacts, scientists say.

Blowing them up?

Well it is only a solution when u have a weapon that turn molecules to nothing, absolutely nothing.
Imagine a bus coming at you blowing it up just ensures that the bus do not come to u as a bus, it comes to u as a twisted metal. Blowing up changes its shape and structure, not its volume or mass.
Just curious what will happen if the moon get hits and lose half its size?

Blowing them up?

For a bus as you say, the twisted metal is one piece so it's the same problem.
If, however, the bus was broken into many pieces things change. Each piece would have less momentum and so would cause less damage.
For the meteor, many small pieces also have the possibility of burning up on entry, whereas the core of a large meteor would get through.

It must be the terrorists!

Those terrorists are to blame, we all know they have graviton rayguns that they use to pull in space bound objects. "Kill the infidel!"

Just kidding, they don't have running water so I doubt they could have rayguns.. or do they?

I better refer to my trusty Home Land Security Rep (or the Support and Security, SS for short) unit. I am sure they will have a "truthful" explanation to the supposed terrorist plot!

Hair the Empire!
