tl;dr You need a camera and either a long lens or a telescope that'll hook to it to see how parallax lets you view the moon from different angles.

So, the moon always shows one face to Earth. Round Earthers believe it's because, despite the moon being a sphere, it's "tidally locked" to Earth and stuck in that position. Sounds suspicious, eh?

Well, Round Earthers also believe we are also on a big sphere, and that sphere is constantly turning. If that's true, we're also shifting in position in relation to the moon. If the moon was a sphere you'd be looking at it from different angles, wouldn't you?

Well, turns out you can. If you can take good quality photos of the moon at dawn and dusk you'll see the moon from different angles. If you take a number of different photos over night and string them together you'll be able to see the angular change. With a good view (you'll need a 1000mm equivalent lens or better) the 3D motion is apparent enough to demonstrate both that the moon is a sphere and that you're moving in relation to the moon.

Looking at the graphic, I see Earth on the left, moon on the right. Two vintage points are shown on Earth, with two blue lines each showing the edges of what can be seen through the telescopes. These lines hit the moon, showing the edges of what will be visible. Comparing the two, it shows how from each you'll see a little more of one edge, and less of the other.

It gets the job done, and probably took little effort. The great thing about interactive forums like this is that anyone can improve on things, like you did by saving 56 kilobytes. Back in the modem days that would have saved a second of download time. Multiplied by 100 viewers, that would be over a minute of saved time.

Rubbish

On the left you have a flat circle and on the right you a flat circle, that's what you actually have now

Checkmate, that's twice now, hence double-checkmate

3 strikes and you're out

Flat circle? He shaded it, and even used a solarizing duotone? filter to account for the sun. Ask an ENIAC operator if that's CGI and he'll agree.

It's still flat as fuck... Hence, all this CGI proves is.... Yes... You guessed it, earth is flat as fuck, PROOF https://youtu.be/4gS6yZwUWjs?t=36

well done OP, well done...

That's thrice btw, you're out
