Imagine being an astronomer in a society living on a planet orbiting an intergalactic star like that: no proper stars in the sky, just smudges of distant galaxies. It might be difficult to discover the "Copernican principle" in such circumstances.
- SiempreViernes 7y agoThere'll be plenty of quasars to act as stars, the big problem is they will be very hard pressed to measure any exosolar distances at all. This particular star is not that big too, so over its lifetime of 1Gyr it'll make it pretty far in the local group. For fictional purposes you could therefore imagine a solar system being sent from one galaxy into another one, that'll make for some interesting astronomical history!
- samanator 7y agoCheck out The World at the End of Time by Frederik Pohl. This is exactly what this is about!

- Analemma_ 7y ago> If we were in the center of the void, we would see no stars in the sky with the naked eye. According to astronomer Greg Aldering, the scale of the void is such that "If the Milky Way had been in the center of the Boötes void, we wouldn't have known there were other galaxies until the 1960s."
