To make a rather long story short, I got interested in visualizing how the planets' orbits precess as a result of the planets' gravitational pulls on each other. And for doing that, I found a paper with solutions extending back 10 million years: Secular evolution of the solar system over 10 million ...

I will concede that a plates-database approach would be inappropriate for Celestia; it would be off on a tangent relative to what Celestia is typically used for. And even a texture-animation approach seems like it might not get much interest here. Perhaps Xplanet might be a more suitable project to ...

I wonder if it might be possible to implement something to display this in Celestia. This could be done by loading paleo-continent map textures and stepping through them. Chris Scotese's site has several such maps, even if not in the most Celestia-friendly form (the larger ones use the Mollweide pro...

It might be interesting to see what the Universe looks like from Mars's surface or Titan's surface, for instance. I imagine that that could be done by rendering a special "atmospher...
