I took two astronomy classes in college, and one of the few things I retained is that in space stuff just keeps floating. Thus, the Star Wars opening text, though originating galaxies away, will eventually make its way to Earth...
That catastrophic eventuality is the subject of this video, which was was filmed over a couple of hours but ultimately took weeks to complete due to all the post-production and editing. And it shows; the effects are pretty impressive throughout.
Though I guess if you're gonna do a high concept YouTube like the Star Wars text raining down on Earth, it's best to do it right. [Reddit]
