What is The Best Method to Use to Measure Earth Curvature?

In your secario above, how can we be sure it is not the sun which is moving?

Seeing all of this talk about the shape of the earth on this forum is getting me to want to test/measure for earth curvature. What is the best method I can use to get repeatable undeniable results proving/showing earth curvature?

get in a plane, not on one, & fly about 43,000' feet up & you'll see the curvature of the earth wherever on earth you fly! if you know an airforce big shot & have power in this country, get in a military jet & fly double the height of that!

We don't notice the others, or they don't exist? I suggest the [latter].

Are you going to quote an experiment from NASA on the moon? I'm talking about real science - testable and repeatable.

I think it is you who has little understanding of physics.

What do you believe is the best method to use to measure earth curvature?

Experience indicates it will not be profitable to answer your question.

You have been starting threads in a disingenuous manner. You begin a thread with a seemingly innocuous question, then start pushing your agenda as soon as you get responses.

In my experience people who start threads like this have axes to grind, chips on their shoulders and will not listen to anything a mere mortal such as myself would have to say anyway. Not saying YOU have an ax or chip, but I've never met someone who started threads that way who didn't have them.

Now people like Moses, Cameron, Dino... I'll talk to them all day. They have beliefs that contradict each other's (and often contradict mine,) but they don't carry chips.

Despite having been top of my class. Have you taken even a single physics class?

I presumed this was a requirement for participating in the Flat Earth threads? With the exception of Gideon, I mean...

Instead, just use the tape at the equator.
Easy peasy ........🤗
