We already have a video in the OP of the effect that you need to counter. The author makes a straight line path away from the moon and it does not point towards the sun.
no he doesn't. that's the whole point. he just points with his finger and assumes that he's making a straight line path. that's a bad experiment. you need to actually make a straight line with something. like, you know, a string. why imagine a straight line when you can use an actual straight line and know for sure?
you're not getting that we're all saying that when we did it, the moon did not appear to be 'pointing' at the sun, just like in the video. when i did it, the sun was near the horizon, and the moon was pointing up and to the left, not at the horizon. but when i used the string to make a straight line perpendicular to the moon's terminator, the taut string pointed directly at the sun on the horizon.
i mean, damn, tom, what do you have to lose by trying it yourself? we're not asking you to document the experience with video or anything. i already agree that's super impractical. we're just saying that this is a quick, easy, and direct way to see for yourself that it's a straight line.
