Thanks Davin. Yeah, me too mate. I could use life experience to explain the whole cosmos, but a man must keep some secrets...

Only one thing I'm unclear about now.. One source tells me that a light yr is 350km/s, another tells me 320, and you say 300.

Wow, thanks Suzy. What a pep!
Most times when I study this stuff, I cross-reference multiple sources of information. It seems to be around (actually a little under) 300, 000 kilometers per second. For all the ambiguity abounding, I try to keep it simple and if necessary (within reasonable limits) round it off or take a simple average. As long as the meaning is not lost and it doesn't become outright misinformation.
