The Quran - A Miracle

Case in point:
In the 30s or 20s, I forgot which, they predicted that we would find background microwave radiation in the universe.
At that time they had no way of testing it. It was a very specific prediction, nothing vague or obtuse about it, it was made as an absolute statement.
Fast forward to the 90s and 00s and we have tons of junk up in space looking at the deep reaches of the universe. Guess what we've found..... background microwave radiation.
That's how a prediction works. Seeing a prediction in hindsight, a post-diction, is useless since you know already know it and it had no power to impart any new information prior to that information already being know.

Actually it was Robert Dicke, a physicist from Princeton, who made the prediction about the Cosmic Microwave Background and its temperature in the early '60s. He set out wuth colleagues to construct a microwave detector sensitive enough to test his prediction but was, famously, pipped to the post by two Bell lab technicians, Arno Penzias and Robert Wilson, who detected the CMB radiation completely accidentally in 1965.

At no point did any of the players in this fascinating story refer to a holy book, however. They did it all by themselves.
