The first part of the video itself closely parallels the H. G. Wells story "The Star," which I recently read. Later, it talks about an asteroid that may come dangerously close to Earth on Valentine's Day 2060.
Update: I mentioned that the video parallels an H. G. Wells story I read recently. The Wells story I am currently reading is called "Empire of the Ants." Hours after posting this, I got on YouTube again, and this was one of the recommended videos:
I'm not going to watch it -- not interested in seeing legs being ripped off -- but "Empire Of The . . . Ants" exactly parallels the title of the Wells story. I have not posted or searched for anything ant-related recently. The only thing Google could possibly know is that some time ago I downloaded The Country of the Blind and Other Stories, a collection of 33 short stories including "The Empire of the Ants."
