for everyone that doesnt know this great site:
http://www.galactica-science.com/on this site are articles about the science behind battlestar galactica, mostly on the star constellations than can be seen in season 4.
they made some interessting discoveries, such as:
-the cylon civil war took place near jupiter
-the trinary star system starbuck sees in her visions isnt a trinary star system. its our sun, a moon of jupiter and tadaaa: earth.
-the demetrius was in our solar system during "the road less travelled" (what makes sense regarding the cylon civil war and leobens drifting heavy raider)
-is helo really heras father?
-"my gods, its full of starbucks!" is the production team sloppy or are there more copies of starbuck running around than you think?
and much more.
