I'm working on building a world in a fantasy setting that exists basically as a 'hollow earth'. This world is earth sized and earthlike, just hollow with a mini-sun in the center, and humans live on the inside. I believe this is called a 'Concave Hollow Earth'. The reason all this manages to 'work' is unrelated.
For the purposes of this question, the atmosphere of this world is as described in the answer for this somewhat related question, under the 'Thin Atmosphere' heading.
When trying to fathom how different human societies would be if they developed on such a world, one major impacting factor came to mind. At any point in time a large portion of the rest of the world is somewhat visible.
I surmise that this would make much easier to discover the size and scope of the 'surface' world, by orders of magnitude over a traditional planet. Mapping out the world would also likely be a far easier task. More importantly, however, I realized that anyone with access to a reasonably powerful telescope now had access to a global surveillance tool, able to surveil the majority of the rest of the world, save for their closest neighbors.
According to Wikipedia, the earliest telescopes were created and used in the early 1600s.
What would some of the societal impacts be of humans having such ability so early on in their development?
