Mostly because I enjoy it, though also because I think it might help those who have an interest in such things, but perhaps are not interested strongly enough to hunt down the scattered myriad resources that yield all this information. I also think it's interesting to have in a linear, readable form the complete history of everything that we know.
What's with Helios, Terra and Luna?
Personal preference. I think it's silly to call the earth that we live upon "Earth." And our moon is just "the Moon." It creates confusion when speaking about other moons, other earth, and other suns. So just like all the other bodies in our system, our bodies should have distinct names, shouldn't they? They should.
Why is it so dry?
Well, it's a work in progress. I'm torn between providing the hard evidence and providing a relevance and more narrative style. For now, I simply present the facts as clearly and concisely as possible to facilitate an understanding of the evolution of the cosmos, our bit of flotsam within it, and our cultural development in as simple a manner as possible. Perhaps the "Hollywood" version will be a separate, though integrated effort.
Why the boring black and yellow?
Staring at a monitor displaying a white background is like staring into a flashlight. So anyone reading something such as this for an extended time strains their eyes less. I use yellow because it provides a high contrast with the background without being quite a bright or jarring as white text. Anyone is welcome to use a little JavaScript and CSS to change it to whatever they like. Or to use their browser's CSS override abilities.
When is the next update? When will you add climatology? Where's the evo-devo tree?
Patience, young Skywalker. I do have plans and ideas floating about to modify, extend and generally fancificate things around here. This is a spare time deal, though. So there's no schedule or overarching strategy. At least not until I receive funding, and I don't hear the sweet creak of wallet-leather unfolding.
