The Micheal Whelan cover to Isaac Asimov's 'Foundation's Edge'. Amid the ruins of an abandoned world, a lone explorer looks up at a very-nearby galaxy taking up most of the night sky.
Also worth mentioning that it took 100+ years for Seldon's Plan to be fully washed of the Mule, from the 2nd book almost to Golan at the ~FE 500 midpoint.
So scrubbing the Earth will take some time and stay messy for a while 😬 #FoundationsEdge #booksky
Still it's not the worst allegory.
