Before you all piss your pants with worry and declare your love to your next door neighbour before its all over, NASA are simply referring to our civilisation from an electrical prospective!
Yes, those boffins in the US enjoy issuing these types of cataclysmic statements to keep all us dullards on our toes. They call them 'War of the Worlds' statements named after the movie that convinced nations that mad killer aliens had landed.
'We run a bi-annual sweepstake to find the best statements to release,' said one NASA representative. 'The winner gets to meet the president at the Whitehouse.'
So, is Obama in on the game? 'Oh no, whatever gave you that idea. We just tell him the winner has delivered nuclear power from water or something like that and then retract it later.'
So what's the next statement we asked him? 'A giant smog monster,' he said. 'It will come from the depths of the ocean after eating the oil from the BP spill. We will announce it sometime early 2011 and use the story to promote the remake of Godzilla Vs The Smog Monster out late next year.'
