You'd be wrong to say that, too.
Name Calling or general rude behavior is no longer acceptable in the Cafe, We are adults which means that we should be able to debate without resorting to name calling.

\That was a very rude post, please substantiate your position with evidence not ad hominem attacks.

Very good. Who did I name-call?

Fine, I have presented many persuasive arguments, please debunk one of them in a post in a civil manner. Thank you.
Add each of your arguments to the Google search bar one after the other, and append the word "debunked" to them.

Please.

You, yourself, have committed that violation multiple times in this thread alone. And no, I won't show you so you can delete them

Circa 200BC


Illustration showing a portion of the globe showing a part of the African continent. The sunbeams shown as two rays hitting the ground at Syene and Alexandria. Angle of sunbeam and the gnomons (vertical sticks) is shown at Alexandria, which allowed Eratosthenes' estimates of radius and circumference of Earth.


Eratosthenes calculated the circumference of the Earth without leaving Egypt. He knew that at local noon on the summer solstice in Syene(modern Aswan, Egypt), the Sun was directly overhead. He knew this because the shadow of someone looking down a deep well at that time in Syene blocked the reflection of the Sun on the water. He measured the Sun's angle of elevation at noon on the same day in Alexandria. The method of measurement was to make a scale drawing of that triangle which included a right angle between a vertical rod and its shadow. This turned out to be 1/50th of a circle. Taking the Earth as spherical, and knowing both the distance and direction of Syene, he concluded that the Earth's circumference was fifty times that distance.

His knowledge of the size of Egypt was founded on the work of many generations ofsurveying trips. Pharaonic bookkeepers gave a distance between Syene and Alexandria of 5,000 stadia (a figure that was checked yearly).[16] Some say that the distance was corroborated by inquiring about the time that it took to travel from Syene to Alexandria by camel. Carl Sagan says that Eratosthenespaid a man to walk and measure the distance. Some claim Eratosthenes used the Olympic stade of 176.4 m, which would imply a circumference of 44,100 km, an error of 10%,[16] but the 184.8 m Italian stade became (300 years later) the most commonly accepted value for the length of the stade,[16]which implies a circumference of 46,100 km, an error of 15%.[16] It was unlikely, even accounting for his extremely primitive measuring tools, that Eratosthenes could have calculated an accurate measurement for the circumference of the Earth for three important assumptions he made (none of which are perfectly accurate):[17][16]

  1. That the distance between Alexandria and Syene was 5000 stades,
  2. That the Earth was a perfect sphere.
Eratosthenes later rounded the result to a final value of 700 stadia per degree, which implies a circumference of 252,000 stadia, likely for reasons of calculation simplicity as the larger number is evenly divisible by 60.[16]Repeating Eratosthenes' calculation with more accurate data, the result is 40,074 km, which is 66 km different (0.16 %) from the currently accepted polar circumference of the Earth.[17]

Seventeen hundred years after Eratosthenes' death, while Christopher Columbus studied what Eratosthenes had written about the size of the Earth, he chose to believe, based on a map by Toscanelli, that the Earth's circumference was one-third smaller. Had Columbus set sail knowing that Eratosthenes' larger circumference value was more accurate, he would have known that the place that he made landfall was not Asia, but rather a New World.[18]

Yes, only after repeatedly being attacked with names first and only at those who did so first. Go check the record.
I don't have to, unlike you I'm not interested in minutia and splitting hairs. You called Jim out and threw rules around when you have violated them. Period. Not interested in any justification or rationalization. You broke the rules.

Here is one for you, please explain why the sun's light appears localized at 15:25 of this video.

What you all share in common is the pointed questions without supporting mathematical evidence, and only serves to demonstrate your blatant lack of scientific understanding.

Where is the actual data to support these claims? All I'm reading/hearing is questions like "why do the stars move this way, or why does the Sun move that way, or how would I be able to see this object from this distance? ..." Followed by "this YouTube video 100% proves that ..."

Here's a question for your questions: how many NASA employees (just one of the many space agencies in the world) are there currently on the payroll, and what proportion [of them] would you suggest knows the work and calculations they're doing at their desks on the daily are fraudulent and 'unscientific'?

Thanks for contributing in a positive manner. Eratosthenes's math works just as good in the flat earth model if the sun were 3000 miles away. Light shining down makes a shadow. We all know that. 180px-SunAnimation.gif

That's fine. Do you have any proofs of a round or flat earth to provide today?

"Eratosthenes's math works just as good in the flat earth model if the sun were 3000 miles away. "

Prove it. Show your work please!
