Just read an awesome short tale from the master of combining religion + sci-fi elements - Arthur C. Clarke.
It's called The Nine Billion Names of God
I want to read all of his books now. Anyway, in the meantime here are quotes uttered by him:
The only way of finding the limits of the possible is by going beyond them into the impossible.
Any sufficiently advanced technology is indistinguishable from magic.
It may be that the old astrologers had the truth exactly reversed, when they believed that the stars controlled the destinies of men. The time may come when men control the destinies of stars.
There is hopeful symbolism in the fact that flags do not wave in a vacuum.
