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.

Very poor cgi skills you have here

Even a fucking ape could come up with better than that...

So you don't like things abstracted to the essentials?

Hm

That's not even things abstracted to the essential sorry

First of all, it's a jpg, that's a very poor choice for a precision graphic with 4 colors, gif or png8 would have been much more suited to begin with, and ancient... Possible connection with ancient aliens... Proof: Shit up there, is 75,3 kB.... This https://pic8.co/sh/tN6eHF.png is 19,3 kB...

Conclusion: I win, and you lose...

Forever

Checkmate faggot, checkmate!

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.

LOL "precision graphic". I threw that together in 10 minutes in a 30 year old paint program, just to illustrate the concept. It's not even to scale.
