“notice the shadow on earth is upturned when it should be a flat line or curved down”
Umm, the shadow is curved because you are looking at the terminus line, the point on the earth where the division between day and night occurs. Oh yeah, and that line appears curved because the earth is a SPHERE.
My point: There is no consistency in how these ‘terminus’ lines are shown in NASA photos of the earth from the moon in the same horizon shots. Upturned line, downturned line, straight line...just depends on the cgi artist interpretation, nothing from a real photo.
Your confidence in your conclusions based on the sources you trust is your privilege. Snarkiness does not contribute to the discussion but does help identify those champions of Settled Science. Thinking people realize there is no such thing.
