Sure but we don't want to let them know that we know nod nod wink wink say no more
Ya, but... Dinchya know? We're just gullible sheep willing to believe everything they and the government tells us. They've washed our minds with the radio frequencies they deem illegal and their oligarchical media propaganda... DUH!No.
Could Earth become flat as a pancake in the future for whatever unknown reason, maybe, but there is no reason to assume that to be the case.
I don't get the impression that you really understood what I was trying to explain.
In one of the other replies, I wrote this to you "Science doesn't simply prove something right or wrong, it is a misunderstanding a lot of people make. Science tells us what is definitely not true".
That the Earth is flat falls in the category of something "definitely not being true". A lot of people (educated) already knew this back then.
Have you ever heard of Eratosthenes?
If not then he was the first to calculate the circumference of the Earth and based on wiki he was born in 276 BC and died in 194 BC. But his experiment can be seen here.

What it shows is him measuring the shadows at two places, Alexandria and Syrene at the same time. Based on that he could calculate the circumference of the Earth. You can read more about this experiment if you want to know all the details. But the interesting thing is, that the way the shadows fall at these two places demonstrates that the Earth is round, they couldn't fall like that on a flat Earth.
This experiment was done almost 2500 years ago and our equipment for measuring these things has become much better, so if the Earth was flat we would know.
So Earth is definitely not flat!!, that doesn't mean that it will stay spherical forever, that is again what I mean by science not working in absolutes.
If you want to have any chance of convincing anyone that the Earth is flat, you have to demonstrate it. Make a testable experiment (using correct science, as flat earth people often use the wrong ones) that demonstrates that the Earth is flat. As I also told you earlier, nothing is gained from disproving the main science, it doesn't automatically make you correct, you still have to demonstrate your own theory. And if Earth is indeed flat, then it should be fairly easy to come up with an experiment that demonstrates it.
The problem with Eratosthenes's experiment is that even though it does support a spherical Earth and it does give us a fairly accurate measurement of the size of the Earth is that it does not prove that the Earth is a sphere.No.

Wow! An amazing example that even a stopped clock is right twice a day. Yes, two points only do not prove a spherical Earth. It would take three points to do that. Do you seriously think that the concept has not been tested with multiple lines. As I pointed out in my prior post, lines of latitude prove you wrong.Umbra and penumbra exist because the light from the sun is not parallel, do you agree?
Just for you I'm opening a new thread for Eratosthenes then we can stay on topic here.
ERATOSTHENES DID NOT PROVE THE EARTH IS A GLOBE!
The Eratosthenes experiment works on a flat earth with a small local light source. The Eratosthenes experiment depended on all the light from the sun being parallel, but even the globe model claims it is not!www.religiousforums.com
Okay, so you do not understand what a margin of error is. For almost all practical purposes the rays of the Sun's rays are parallel when they hit the Earth. There are rare exceptions when that minor error from perfectly parallel matter.Oh, yes I have very much heard of Eratosthenes!
Are you willing to sacrifice his claim to the light from the sun being parallel or sacrifice how umbra and penumbra work?

We can open an entire thread dedicated to that topic if you wish.
But if you increase the distance between the places you measure, the shadow would change on a spherical Earth compared to that on a flat earth, right?The problem with Eratosthenes's experiment is that even though it does support a spherical Earth and it does give us a fairly accurate measurement of the size of the Earth is that it does not prove that the Earth is a sphere.
I know, BLASPHEMY!! Right? The problem is that only two points were used. With a Sun that is near a Flat Earth one could get the same results. One needs a third point on the sphere or the Flat. Then one or the other would be refuted. And that of course has happened. It can more easily be done with the North Star since one does hot have to wait for a particular day to run the experiment. With a near Earth Polaris one would could still replicate the observations of any two points on a spherical Earth. But one will not get the same results using a flat Earth if the Earth is a sphere. Also if the Earth was flat one would find that the distance between lines of latitude would vary. But we know from endless tests that the distances between lines of latitude are constant. That is mathematical proof of a spherical Earth. The concept of Nautical Miles is based upon the observation that the distances between lines of latitude are consistent.
April 2024 is the next Great American total solar eclipse!!!Okay, so you do not understand what a margin of error is. For almost all practical purposes the rays of the Sun's rays are parallel when they hit the Earth. There are rare exceptions when that minor error from perfectly parallel matter.
Here is a question for you: How common are Solar Eclipses? Do they happen every day? No? Okay, at least once a month? Oh still not. Rats well at least once a year? Oh still no. The Moon's orbit is not exactly in the same ecliptic as our orbit around the Sun. Various factors keep that shadow from always hitting the Earth. Those events are very rare so for most cases we can ignore them when talking about the Sun's rays. Do we always have to write "So close to being parallel that the difference does not really matter" when talking about experiments like that of Erasthones?
I do not like your illustration because it incorrectly represents what happens. The Sun distance in the globe model is so far away as to make all rays of light from it parallel. In the illustration your model has an angle due to the Sun's rays not being parallel.But if you increase the distance between the places you measure, the shadow would change on a spherical Earth compared to that on a flat earth, right?
If we assume you dug two holes 50 km apart and then measured the angle on both a spherical Earth and a flat Earth you would probably get the same result. But if you increase the distance between the two holes so one is dug on the curvature of the Earth then they wouldn't give the same result, would they?
View attachment 79881
Just to explain what I mean, let's just say that there are 100 units between the holes and given that one of them is at the curvature of the earth whereas the other is on a flat earth, then the angle of the shadow would be different between the two holes or did I misunderstand that? (Not the best at math to be honest )
No I wasn't aware that the distance was the same. But would it matter whether the rays are parallel or not?I do not like your illustration because it incorrectly represents what happens. The Sun distance in the globe model is so far away as to make all rays of light from it parallel. In the illustration your model has an angle due to the Sun's rays not being parallel.
What you can do with a flat Earth and a very (very very) close sun is mimic the same angles as one gets on the globe Earth when one uses only two points. I need to find a pen and paper to work out specific examples. Are you aware that the distance between ten degrees of latitude is the same anywhere on the globe? That is something that the Flat Earth cannot explain.
Yes, it makes a huge difference because now in this case you are misrepresenting the Flat Earth model. They do not have parallel rays in their model. To compare the two you need to compare the models accurately.No I wasn't aware that the distance was the same. But would it matter whether the rays are parallel or not?

The angle in the hole would still be different (the blue angle) compared to that on a flat earth as the distance between the holes is increased, obviously, the position, distance and size of the sun etc. have to be the same in both experiments.
But in that case, the sun would have to visibly change in size, depending on where you make the measurement from. If person B in your image moved closer to the E, then he would be closer to the sun and it would appear much larger for him than Person A. How do they account for that when it's not like that in the real world?Yes, it makes a huge difference because now in this case you are misrepresenting the Flat Earth model.

The globe Earth model has the Sun so far away that the angles are caused by the shape of the Earth. In the Flat Earth model the Sun is verry very close. And the difference in angles are due to the different angles to the Sun.
I have not found the image that I want yet but take a look at this one, this is how Flat Earthers would measure the height of the Sun:

Yep, the Flat Earth model fails again and again and again.But in that case, the sun would have to visibly change in size, depending on where you make the measurement from. If person B in your image moved closer to the E, then he would be closer to the sun and it would appear much larger for him than Person A. How do they account for that not being the case in the real world?
It sounds like you really trust the government then. Am I correct to assume you are triple vaxxed by now?
If you don't trust the CIA, FBI, or FDA, what makes NASA special enough to trust them?If you're wondering whether I trust the government, my response is not really, but I trust it considerably more than a flat-earther and an anti-vaxxer.
Who says that we don't? They are all trustable to a degree. The CIA will generally be honest, but if the information could harm the US's security it will either be not given or sometimes even wrong on purpose. The FBI tends to be much more reliable today. They get in trouble for lying. The CIA has a valid excuse for sometimes lying. Who on Earth thinks that the FDA is part of any conspiracy? I have only seen science deniers make that foolish claim. And the same for NASA.If you don't trust the CIA, FBI, or FDA, what makes NASA special enough to trust them?
I do.Who says that we don't?
I had that discussion with someone above but that is correct, you would need three holes from what I understood.This is Neil de'Grasse Tyson's diagram. He even acknowledged the shadows still work on a flat earth if the sun's rays were not parallel - which they aren't as demonstrated by the existence of umbra and penumbra. I explained this in the OP.
Let's keep the Eratosthenes conversation on the Eratosthenes thread. I directly refuted the 3 hole argument there.I had that discussion with someone above but that is correct, you would need three holes from what I understood.
But if one extra hole is all that is needed for the flat earth model to fall apart it is not really all that sound and doesn't change the original issue. Which is that all experiments and observations have to support a flat earth otherwise it is not valid.
I do.
I seldom afford trust to the 'alphabet groups' of the world governments, with a particular bias against the ones I'm subject to in the USA. If there is a shadow of doubt that they may be acting nefariously or for political/societal gains, any trust is rescinded.
FDA: Criticism of the FDA - Wikipedia Cares more about profits and padding the pockets of lobbyists and pharmaceutical companies than it cares about what it was created for. Monsanto, err.. Bayer and their Roundup product being one of the more recent examples.

Fool me once, shame on you. Fool me twice, shame on me.
But you keep ignoring the fact that they do not work if one has three different points.This is Neil de'Grasse Tyson's diagram. He even acknowledged the shadows still work on a flat earth if the sun's rays were not parallel - which they aren't as demonstrated by the existence of umbra and penumbra. I explained this in the OP.
