Well, you did ask about eschatology. In my book, that is the final four; death, judgment, heaven and hell.
As a matter of fact, the Catholic Church has said from the start just exactly what you said though about the stars, etc. I reference Matthew 17 and 18 (the skies will be darkened, and the moon will shed no light) as well as Revelation (which also states that there will be great darkness, with one-third of the stars being ‘swept from the sky’ at the time of the great tribulation.)
That the Bible did not specifically say that this would happen due to ‘proton decay’ does not negate the fact that scientific theory seems to support not only Genesis (with the universe starting in darkness and then suddenly ‘light’ comes into play) but also Revelation and Matthew as to the ‘end of days.’ 2000 years on, and if anything the Bible is reinforced by science.
