We are lucky that we live in a sweet-spot era where the universe is old enough that we have 13 billion years to look back on, but young enough that all the galaxies haven’t receded behind the cosmic horizon yet due to the accelerated expansion of the universe. In some billion years, intelligent beings will only have historic records, if anything at all, to look back to how the observable universe used to be filled with billions of galaxies.
