If it shows there's SFA drop off after pulling the string tight then you can always pull out their atmospheric refraction get out of jail card.
"Hi, I would like to buy a mile and a bit of string, what aisle is it in?"
Ahh, that would be aisle 23. I am not sure we have a whole mile in total, but there should be a few hundred metres in stock.
"I want it as one length of course, so where do you keep that?"
A mile of string? Are you crazy? We don't keep miles of string here.

Try a little harder then.
I should try harder to figure out why you can't answer questions?
Figure out why you keep telling me to do an impossible experiment instead providing your own proof?
I'll ask again.
What's your preferred/favoured proof that the earth is not a globe? And can you provide an example where you or someone has demonstrated it in real life?

....Now if their globe theory holds true the middle point of the string would be higher than the two ends.
Yay, arguing with PM33 about the world being flat. It's going to be a productive day today.
But - I'm not sure I understand the hypothesis. Why would the middle point of the string be higher ? Would it not be lower if the ground curved between the ends ?
So anyway, I just been to Bunnings and I got myself a length of string 40,000 km long. It was the last one they had, on special. I tied one end to a pebble on the beach and stretched the other end out, 40,000km away.
I can confirm two things :
(a) At the end of the 40,000km I was back at the same pebble the first end was tied to.
(b) I am now walking back to the middle to measure the height. It is along way to walk, about half-way back around the world.
No need for string. Stand at the waters edge at Dutch Inn, can you see Rottnest Island? Walk up the hill, can you see it now?

Your proof assumes light travels in a straight line. Not near the water it doesn't, refracts in layers of air, sometimes Rottnest hovers above the water.
Mysterious floating islands off the coast of a continent that doesn't exist? Now we're really entertaining bizarre conspiracies!
Do serious flat earthers also believe in alien visitations, or are those groups mutually exclusive?
so the 2.08 is a function of the curvature of the earth????
If you were on a different planet, it would be a different number?
Bigger if on Saturn, smaller on the moon, but the rest of the formulae the same?
I haven't been able to figure out the relevance of 2.08, but I reckon you are correct. If the Earth was flat we would only need Pythagoras' theorem (3,4,5 triangle), instead we had to wait 300 years for Eratosthenes.

"... The value 2.08 is a conversion factor used to convert the units of the result from meters to miles, given that the other terms in the formula are in meters. This conversion factor ensures that the result is in the same unit as the input parameter M (which is specified to be in miles).So, the 2.08 is not derived from the geometry itself, but rather it's a conversion factor to ensure the units are consistent in the final result...."

Just being curious I also asked the AI overlords to explain Flat Earthers ;
"Belief in a flat Earth is often rooted in a combination of skepticism towards established scientific knowledge, misinformation, and conspiracy theories. Here are some reasons why some people believe the Earth is flat:
1. **Misinterpretation of Evidence**: Some individuals may misinterpret everyday experiences or observations, such as the apparent flatness of the horizon or the lack of perception of Earth's curvature in day-to-day life, as evidence that the Earth is flat.
2. **Selective Attention to Information**: People who believe in a flat Earth often focus on information that supports their belief while ignoring or dismissing evidence to the contrary. They might cherry-pick data or rely on pseudoscientific explanations to reinforce their convictions.
3. **Distrust of Authorities**: There is a subset of individuals who harbor a deep distrust of established institutions, including scientific organizations and governments. They may reject mainstream scientific explanations as part of a broader skepticism towards authority figures.
4. **Conspiracy Theories**: Some flat Earth beliefs are intertwined with conspiracy theories that allege a cover-up by governments, space agencies, and other organizations to conceal the true nature of the Earth. These conspiracy narratives often appeal to individuals who are already skeptical of authority or feel marginalized in society.
5. **Online Communities and Echo Chambers**: The internet has provided a platform for like-minded individuals to connect and reinforce each other's beliefs. Online communities, forums, and social media groups dedicated to flat Earth theories serve as echo chambers where dissenting views are discouraged, and skepticism towards mainstream science is amplified.
6. **Psychological Factors**: Belief in a flat Earth can also be influenced by psychological factors such as cognitive biases, confirmation bias, and the desire for belonging to a group with shared beliefs. People may find comfort and validation in joining a community that shares their unconventional views.
7. **Lack of Scientific Literacy**: For some individuals, a lack of understanding of basic scientific principles, such as gravity, geometry, and astronomy, can contribute to the acceptance of flat Earth beliefs. Without a strong foundation in critical thinking and scientific literacy, pseudoscientific claims may seem plausible.
Overall, belief in a flat Earth is a complex phenomenon influenced by a combination of cognitive, social, and cultural factors. Debunking flat Earth beliefs often requires patient and empathetic communication, critical thinking skills, and a willingness to address underlying fears and concerns."
I see... AI is a government con to entrap us all into something or other...
Whatever it says is clearly a lie, unless it agrees with me.
Well all know that water finds its level, and if the earth were round it would all fall off. Obviously

There's that Scientific Illiteracy in action. Gravity works in all directions, so the water is attracted to the centre of the disc.

Not to mention how a disc self-assembles while under the force of gravity. Sure, all other things seem to clump together as close as they can to form a sphereoid, but earth just went with a disc.
I can't work out if Mr Milk is trying to usurp PM33 as troller of the decade or not.

I still can't tell if you are being serious. I thought my post was obviously a joke, but now I am not so sure.
But how do you get a disc if gravity works in all directions? At what point does the circumference of the disc get pulled into the core and end up with a lump of matter? Its almost like all that pressure would create a lot of heat and melt rocks and things.

To create heat would require friction, not simply balanced stresses. So long as the supporting beams remain strong you're in no danger of faling into a volcano

Since when did anything from Ikea self-assemble. You have lost touch with reality and have never built anything from Ikea.

The earth was built by the Magratheans
well I guess it would create a disc if it was spinning fast enough, a disc with a bulge in the middle. But then accretion would be problematic. It would need to accrete first then start spinning, to the point where the out region is almost getting flung off. Don't think we'll ever see a world like that.

I think your Ikea instructions for the assembly of your earth are incorrect. It notes that there are side effects of gravity resulting in heat. Do not store your earth near anything inflammable.

I had to think about that for a while, but over the course of 50km cogitating, it came to me. Polarised gravity.
It's why you can't re-use your 25km length of Bunnings string to measure how far down it is off the edge, as well as how curved it isn't.
The string just gets sucked back towards the middle and won't dangle.
