This doesn’t seem to be a movie script, actually. The Yahoo site it’s from has entertainment news, gossip, and tabloid reports, and this is from the latter category. There are a whole lot of other articles from the Weekly World News included on the same site (my favourite is the one where the Chinese finally admit that they can’t tell each other apart, either).
As for all the stuff about a giant cloud of mutated Hawking radiation coming towards us, I suspect that the writer simply read a few headlines in an astronomy journal and put together the article from that. They might as well have written about Mars emitting a cloud of kippered herring that will bombard the Earth. Either article would be about as scientifically accurate. For anybody who actually might have believed the article: don’t worry, it’s all nonsense.
