On a tidally locked planet, a refugee population of humans has landed and walled off a large section of the world’s habitable zone, the region between the night and day side that encircles the planet. I imagine this wall to be preposterously high, smooth and relatively unblemished by time's passing. It has a footprint roughly the size of Australia, reaches...1?...2? Kilometers into the sky. At this point, it doesn’t really matter. All we need to know is it doesn’t look natural and it would be impossible for the native population to get over it or around it...at least until they’re able to build rockets…
The native population has evolved to a caveman level. There has been no contact beyond the first few years of landing and constructing the wall. Humans have sequestered themselves behind the wall to ensure no further cross contamination between the two ecologies. The humans unpack all their junk and set themselves to building a new earth within the wall/compound/reservation. The myth of the wall begins to permeate the native culture/religion/political structure etc,
I imagine the chapters structured around 1000-100 year snapshots of both the human and native populations evolving together separately.
The main question or thought experiment I’m trying to imagine are various hurdles a thinking species would have to overcome while rationalizing a giant wall they can’t get through or over no matter how hard they try.... (That is until they eventually launch a rocket and finally take a peek) What I’m interested in is the “enlightenment” snapshots, The intellectual turning points that propel them to an early 20th century understanding of the world.
The answers I’m interested in on this forum are questions I need to be thinking about. Such as: Is the land surrounding the wall sacred? Or is the native population concerned there is a void in the knowledge of their planet’s topography even though it’s impossible to visit the polar regions do to vast temperature differences? Would there be different aspects to the native populations enlightenments? Such as the discovery of flight, and how it would probably come pretty early in their evolution because of the walls cultural driving force.
Again, I don't really need answers just questions to posit
I fear this question may still be too broad or not fit this forum :/
