Meet Earth

I've been giving this much thought and i believe we can find the edge of the walls of this perspective prison, it would require the use of a laws laser system and a few high powered telescopic spotter arrays and a bit of technical know how https://ediovision.blogspot.com/2018/09/how-to-find-edges-of-transparent-dome.html

we can assume some things about our environment, such as it must have fixed boundaries and a roof and a dome would be the easiest and simplest answer, it fits the facts and observations, so we must also assume that we do not actually move, but our environment is moved around us generating the land masses as they enter the circle of sight, knowing this we can simply create a giant holographic picture on the sky of a "gradient image" and look at the angles of optimum reflectivity to see if the image has been lightened in the darker areas and has become "washed out" by the diffusing of the light photons, it would have to be repeated for a full 360' sweep in order to find any exits and i think it can be done by using the The Dome as an Optical Component

The largest optical element in a full-dome theatre is the dome itself. The fact that this projection surface is curved (in contrast to a flat screen in a mainstream movie theatre) causes the dome to act as an integrating sphere. Integrating spheres are widely used in optical engineering to smooth out the directional characteristic of a light source that is to be characterised, averaging over all spatial directions. IE the photons are evenly distributed in all directions, A projection dome can be modelled as an integrating sphere cut in half. When content is projected onto the dome, light is being scattered and reflected not only into the eyes of the spectators, but is also spread over the entire dome surface. This cross-scattering compromises contrast as dark areas in the projected image will now appear brighter. so if you can find the sweet spot you can figure out just how big it really is and if you take multiple images 360', you could use the distortions to map any hidden objects /doorways or structures thereby revealing to you the edges distance from you, it seems pretty logical to me, how about you?, i suppose this theory is academic because i don't have access to said laser systems to do this, but if i did i'd say its worth a shot, whats the worst that it could do apart from show a rather boring big picture in black and white checked squares in the sky for a few minutes, as apposed to unveiling the true shape of "our world" its defo worth it ;) #peace
