When we're out of people to kill...

Been meaning to blog about this for some time now...
I swear this is an actual headline from Reuters and i didn't make it up.

How to Prepare for Alien Invasion

The authors of a new book, "An Introduction to Planetary Defense" are serious when they say that

"The probability really is there that aliens exist and are old enough to have technology to enable them to come here."

Quacks that watched too much Star Trek and Alien movies maybe? Actually, both authors have advanced degrees in astronomy and physics and have done consulting work for NASA. (-_-") After intense calculations, they reckon that there are thousands of intelligent alien species in our Milky Way, and there is a 'high probability' that we're visited by one or two every century.
And what have they concluded from this speculation?

Failure to prepare may mean mankind will have to dig in and fight with improvised weapons and hit-and-run tactics, much the same way Islamic extremists have battled the U.S. military in Iraq.

Oh look, it sounds like America ran out of places to bomb. Let's form a defense plan for the entire universe instead. On the other hand, maybe if we have to build defenses against some common enemy, we'll stop fighting amongst ourselves. Maybe, oh maybe.

p.s: seen the new episode of Heroes? Spoooky....
