[QUOTE="Spatzimaus, post: 2431834, member: 3051"] I'm a seventh-year grad student in astrophysics. (Sigh.) So, I'll give the physics sidenote. Stars as small as our sun can't form black holes, they're way too small for that, by a factor of... well, it depends on the circumstances, but let's say 10ish. The minimum mass of a "stable" black hole is larger than our sun, and the process of creating a black hole would, in theory, eject the majority of the star's mass, so you'd have to start off much larger than that. Our Sun is going to end up as a simple White Dwarf star; of course, this won't happen for a good five billion years or so, and most of the sun's gas will be blown away in the process (which would kill us, incidentally, even ignoring what it does to our orbit). And you can't go with a larger star, either. Any star large enough to form a black hole would put out massive amounts of UV radiation (not good for life) and have lifespans measured in only millions of years. Of course, we've only actually seen a small number of black holes (and that's "seen" in the sense of "noticed the effects of"; they're hard to actually view at long range), but the theory behind them is pretty simple. Anyway, I'd say dump the physics. This is a mystical world, where the sun is managed by gods. No need to rationalize things in terms of modern sciences, unless you really want to. [/QUOTE]
