For anyone who believes the Earth is flat I am not here to say you fell for a psyop, call you names, or insult you in general. I just have a few questions and observations I would like to have addressed. I am being respectful so please do the same.

1) I hear many people who are flat earth believers say sunrise and sunsets are perspective. My question, why is it if when you use a solar filter on a camera you can photograph the sun from sunrise to sunset you can clearly observe the sun come from behind a physical barrier, stay the same size, and then disappear bottom up behind a physical barrier? If the Earth were flat the sun is small and local, the sun should change size as it moves farther away from observer but this is not what is observed.

2) when walking cross country, why is it if I use compass, walk one mile, turn 60 degrees, walk one more, turn 60 degrees, and walk a third mile ibwill not end up near where I began. But doing the same thing with 90bdegree turns inl donl end up back where I started? If the earth were flat why would I need to make a triangle with internal angles equal to 270 degrees as opposed to 180 degrees?

3) why is it objects, regardless of their mass all accelerate at the exact same rate towards the earth when dropped? [Note you can't say density as density isn't a force and cannot give objects a vector and you cannot say buoyancy as to calculate buoyancy you have to factor in gravity]

4) why is it a pendulum drifts differently based on you position on earth?

5) why does Earth have an atmospheric pressure gradient starting at 14.7 psi and gradually decreasing as you gain elevation eventually reaching near 0? If the earth were contained then the gas particles would be hitting a physical barrier like the flat earth claims to be why do we not have a uniform pressure regardless of altitude?

6) why does every gyroscope on every aircraft all detect a 15 degree per hour drift regardless of it they're moving or stationary? [Note you can't claim its detecting the movement of the sky as the gyros are sealed and can't detect movement of the sky]

7) what would be the reason to lie about the shape of the Earth? [Note you can't say to make us turn from God, as of 2019 nearly 71% of all adults on the planet believe in a God or afterlife, most of those being Abrahamic religions so clearly this can't be the case]

8) why does a compass built in the northern hemisphere not work in the southern?

Again not being a dick I just want a real, scientifically based, intelligent answers, not the Bible says this, or this ancient culture believed this.

here is the post.

A map that has accurate measurements DOES bolster your point.

I can measure the earth's curve, I can measure the distance to the moon and sun. Do that using flat earth. If the earth were flat you should be able to easily triangulation the distance to the sun/moon.

Makena prediction, the heliocetric model can predict, comets and eclipses for example. Eclipses especially down to the minute. What flat earth math can do the same?

There is no flat earth map that accurately represents distance and direction. There just isn't.

I think we can just leave it here.

And of course I'm going to confront the challenge dude. I'm not too chicken shit to defend my stances. Or share my observation, minus some minor insults and you calling me a liar about my lab, this hasn't been over the top uncivil and stayed on topic more or less. It's better than any other discussion I've had with any flat earthen before.

lol no you can’t. It’s not even worth reading past that point when you’re just making dumbass assertions you can’t and won’t substantiate.

Let s=1km.

Given that the radius of Earth is 6371km, we can find

θ=sr=1km6371km=16371rad=1.56∗10−4rad I think h could found by

h=6371sin(π2)−6371sin(π2−1.56∗10−4)=7.84∗10−5km

which converted to meters would result in a curvature of 0.07mkm.

Earth's curvature over 1km

Yes I absolutely can calculate Earth Curvature

That’s a pretty big given, LOL.

Ever heard of begging the question?

That’s just an assertion that relies on appeal to authority.

Unless you can show how you know this figure and can demonstrate it, it invalidates any calculation based on it.
