Had the series been made today no doubt there would have been many more habitable planets and moons, and many more non habitable. The Galaxy was describe by Tigh as a "pretty barren place" but since that episode, and especially since the shooting of the series ended, its been shown the galaxy is anything but barren. Its pretty accepted by scientists that future generations will find the Galaxy chock full of habitable planets, probably in the millions, and many, many billions of planets and moons as well. Hell the Milky Way, a rather small Galaxy, has 200 Billion stars alone.
There so many ways Blood and Chrome could have gone it really breaks my heart they didnt run with it.
If your a BSG fan and havnt seen the movie "The Plan" you really should. It does fill some holes and explain the cylons a little better. It has one of my favorite qoutes in it when a #6 model is listening to Cavil bemoan about how all the other cylons on the ship keep letting him down cause they keep getting involved with humans emotionally. She tells him drunkenly "you can't declare war on love".
I love that series. Every minute of it.
