There'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!

> 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."

Via https://en.wikipedia.org/wiki/Bo%C3%B6tes_void. Pretty eerie to think about.

Also _Against a Dark Background_ by Iain M. Banks. It describes a very, very old civilization with no stars close enough to even think about interstellar travel.

Check out The World at the End of Time by Frederik Pohl. This is exactly what this is about!
