Admittedly, Poul Anderson's "Flight to Forever" features a Galactic Empire because it was pulp sf published in 1950 but it also presents a series of different future periods and is more than the sum of its parts. See Brontothor. The "Flight to Forever" chronology is summarized in that post and its two links.
I must venture out into the hot sun of the warming Earth but will hopefully return here later today.
Ad astra.

Note that for most of the history of life on Earth, temperatures were about 10 degrees hotter than now and there were no polar icecaps, nor any mountain glaciers.
and everything alive now is adapted to the relatively cold conditions of the last few million years.
Humans aren't. We're a tropical species by origin.
Humans do reasonably well at the current equatorial rainforest temperatures and need clothing for survival far from the equator. However, I have seen the claim that a modest rise above current temperatures would result in the 'wet bulb temperature' sometimes rising to humanly lethal levels in some places like India or equatorial Africa.
Kaor, to All!
Well, I'm glad evolution rid us of the monkeylike body fur our distant ancestors once had! (Smiles)
Ad astra! Sean
