The basis of why this would be faked isn't the topic of this discussion. Perhaps make a topic around the purpose of faking 'space' missions? That might yield some of the answers you're looking for.
I got 92%.
Actually, the topic of the discussion is in the OP: The curvature of the earth clearly visible...flat surfaces of the ISS are also visible...no lens distortion...how explained by FET?
Is your explanation: The video is fake therefore the ISS and the curve seen are fake?
My explanation would be closer to 'if the video is fake, then discussing any specific detail within it is irrelevant.' Like discussing how 'realistic' Star Wars is.
The discussion parameters have been changed. The OP would rather discuss the motives behind faking a space video, rather than its legitimacy. I imagine the answer is fairly simple... 'to make people think that the space video - and everything contained within it - is real.' To what end? Speculation: to further the narrative that we are conducting space missions.
But unfortunately, we're no longer discussing a specific video, but instead we're dealing with hypothetical motives of faking media. I'd have preferred the OP to create a new thread for people to speculate the motives of SpaceX in, and I'd have decided if I wanted to participate.
Airplane "widened" the discussion to "include" the motive(s). So in addition to the curvature issue raised in the OP not instead of. You are not forced to discuss a motive. But sometimes if there is a crime, in this case, potential fakery, it helps to examine the why to potentially lend more credence to what is actually in question.
Again, I'm not sure what you want to discuss. I guess questions are, do you believe that space exploration is not real and that notion is perpetuated based upon your belief that the video is fake? And specifically, aside from the ISS looking vaguely like a model to you in the video, do you have anything directly you'd like to point to? Like why it looks like a model? Or are there other indicators that make it seem so to you, visible wires, lighting, other evidence, etc.,? Are other videos less or more convincing? Just saying, "It looks fake," doesn't offer a lot up to discuss.
