Frost, I still can't figure out why you still indicate that site.
Look here, there's a tutorial page about that video too here --> http://thenewcode.com/500/Use-YouTube-Videos-as-Fullscreen-Web-Page-Backgrounds
If you were enough smart to read, you will see that that page was created using that guide in order to fill an ugly empty space while working in background. A forbidden error page is not good looking
Now I just want to be rational:
The used video is this, published on YouTube https://www.youtube.com/watch?v=W0LHTWG-UmQ&feature=youtu.be
and as you can read on the video description

That's a FREE VIDEO, relased under creative commons by the NASA
So, the site you have linked has taken that video from NASA too, adding a fixed mask on the left that shows a satellite on the right side of it.
There's nothing else to say, intelligent peoples have already understood your silly game. Weak hands are weak hands, none can deal with them. Meanwhile, happy playing
