if matter entering a black hole approaches c as a limit, then perhaps matter leaving a white hole approaches it from the other direction
You should go write the scripts for Star Trek. You'd do a good job, even better than Mr Hawking.
I fail to see much resemblance between christianity and the Ainulindalë, safe Eru = God, Ainur = Angels. That's about it. Melkor can't even be called Lucifer as Melkor didn't start a war against Eru, nor did Eru threw him out down to Arda.
The biggest difference is of course, that Eru made his Valar to create Arda for him, instead of doing it himself... good move for us, as it gave us stories to read on rainy Sundays, but bad for the lads and lasses which are supposed to dwell in Arda.
