Re: [IW]: How to get Different Stars/Constellations?
Even as a child, I knew it was cheese. My family lightly mocked me for enjoying it, being a born lover of real science and all.

Other thing: if you return in time, days become shorter, if you advance, days become longer (it is related with the moon running away from earth. I read somewhere that in mesozoic days only lasted 18 hours. |

As for the precession of the Earth's axis, that only messes up the Polaris=North alignment and the equatorial coordinates. The constellations are still there, just shifted on the sky (in comparison to the Earth's axis) from what you saw last night ten thousand years ago. |

This was used to drag other planets around, dropping one of them into the sun, making it swell up. And making Earth a moon of Jupiter. |

If you're familiar with GDWs other SF RPG, 2300 AD (aka Traveller 2300), it's set in the space near earth and uses data from the second edition of the Gliese catalog of nearby stars--data that had already been superceded by the third edition by the time it was published. That turned out to be pretty important because the universe set a strict limit on how far you could stutterwarp between stars--7.7 light years. A whole lot of background depended on stars staying put. Later observations have made a mess of this version of interstellar space--but only for our universe. If one were to hop into the 2300 AD universe (or one of its echoes, say, during the Twilight War), those stars would be in the "right" places after all. |

If the place is/was high enough tech the reflections and glow from orbital industry, space solar power satellites etc can make it hard to see the stars.

Re: [IW]: How to get Different Stars/Constellations?
Something that occurred to me was in relation to this.
http://en.wikipedia.org/wiki/Galactic_year Even a significant part of this period could have familiar stars or even star clusters being moved behind an opaque nebula. That would make significant differences in the constellations. The necessary scale might be between a Galactic week (5,000,000 years to a month (20,000,000) rather than the whole Galactic Year (230,000,000 years)
