I can't be certain it is fake, but the article doesn't reference any source. Even the author is said to be an "Associated Press Writer". If even the author won't give his name then there is significant doubt as to validity of this article. The supposed nuclear weapons expert, "Noah Cain", who stated that “This has been the most powerful bomb exploded to date,” cannot be found in any encyclopedia I own, nor can he be found on google, wikipedia, hotbot or even in a yahoo search apart from said article.
Also, the anonymous scientist who claimed, “it [the bomb] could have altered the moon’s orbit by a fraction of an inch which over the course of a couple centuries might cause the moon to crash into Earth.” Should not remain anonymous. If this ass hole has such information, than he should come forward, announce who he is, why he thinks it is true and what we should do about it. The fact that he doesn't, only says that he himself cannot validate what is being said with any sort of assurance.
There is also the issue of possible misinformation. The U.S. government is known for creating information that is false, and distributing it among various "channels" for purposes of their own ambition. I wouldn't be surprised if this is another case of bad information leading us to believe that yet another country is out to "attack" the U.S., giving reason to bomb yet another poor nation. I don't want to make this a U.S.A. bashing thread, but even I as an American can see when someone is trying to manipulate me.
I don't post too often, so I'm sorry if my writing is hard to understand or I have any words spelled wrong. To tell you the truth, It's a Saturday night/Sunday morning and I live in Wisconsin. This means I'm a little/lot drunk, and I probably wouldn't have posted at all if I was not. Agree with my opinions or not, I really don't care. Feel free to Flame me, I'm an easy target.
