Awesomeee, I posted a link earlier that directly addresses the video. Even Juju's response is sufficient - you've linked to a video from frankly a nutter who couldn't tell you what science was if it slapped him in the face. And that's one of the kinder statements you could make about him.
You do not need a scientific debunking of the video. In fact, you've probably already read what you need to know on the forums, the likes of Elenin only being 3-4km in diameter, the fact that if it were a much larger object there would be insanely noticeable differences in what we see in the sky (which, lo and behold, nobody see's. I wonder why that is? G'ment cover up? No. Laws of physics? Oh yeah, them.)
There is nothing more to add, unless you want this to turn into a 'Why VonHelton is ridiculous' thread.
