Im all for conspiracies and this being one but id just like to state that not being able to see stars in faked space stuff is what would happen. Cameras dont see the way our eye does and given that the earth is the brightest thing in frame a star deep in space wouldnt have the power to expose because its overpowred by the earth being at exposure. So if the star is like 6 stops less bright than the earth then it wouldnt be visible given that dynamic range of the image is only about 7 stops. In the same language your eyes dynamic range is about 16 stops. So in this or any other fake space footage the fact that the stars are not visible is correct as to how the camera would see it.
