      @@painkey1189 No. Really good question though.
      Consider railroad tracks. Railroad tracks are parallel, but the visual image is not. The tracks converge into the distance. This is because things look smaller when further away.
      Similarly, that dramatic pyramid sunlight effect is the same as a railroad. The sunbeams are in fact nearly parallel, but appear to converge into the distance.
      Another example: go the base of a tall rectangular building. Look up. Notice that the top of the building looks smaller than the bottom. Wait, does that mean it's actually a pyramid after all? No, of course not.
      The pyramid sunbeam effect looks more compelling because there aren't any other distance cues to help us form a 3d model in our brain.

    The rest of the story is equally important. The Greek scholar and his slave took off with a measuring chain and calculated the distance between the two points (about 800 miles ) and with the trigonometry known at that time calculated the size of the Earth, which was very close to Earth’s actual dimensions. There were some scholars of Columbus’s time that believed the earth was spherical but they were way off believing the Earth was about half what it really is.
    Instead of sitting around the columns debating, these two hoofed it from point A to point B. People must have thought they were on a fool’s errand.

      Most scholars at the time of Columbus knew exactly how big the Earth was. The problem was that nobody knew how wide Asia was. Eurasia spans about 130 degrees of longitude, but people of the time estimated that is spanned anywhere from 150-200 degrees of longitude, thinking a sea route to Asia was shorter than it really was.

      @@rogerthomas169 All they had to do to establish simultaneity was to make the measurement at noon on the same date. Noon is established by observing when the sun crosses the north-south azimuth. You don't need any kind of clock. This works as long as the observation points were on a north-south line. Alexandria is not exactly due north of Syene, but it's close enough that it would make no substantial difference in the calculation. The experiment was actually done to determine the size of the earth-- they had already decided the earth was spherical through other types of observations. They had also determined that the sun was so distant that the angular parallax of sun rays could be treated as zero. They had done this through observations of solar angular elevation at distant points on an east-west line with simultaneity being established by making the observations at the moment of a solar eclipse. They had previously discovered heuristic methods of predicting solar eclipses based on observations of the 19-year lunar cycle. They knew the distance between Alexandria and Syene through Egyptian land survey data. This data was meticulously developed to permit adjudication of property rights. The variables you're worrying about were tightly enough controlled to allow Eratosthenes to calculate the size of the earth to within a few percentage points of accuracy. All you had to do to learn all this for yourself was to look up Eratosthenes or earth diameter on Wikipedia. They were smart enough to do all this, but all you had to do was look it up on the internet.

      @ptek69 6 месяцев назад +2

      Not a flat earther by anymeans, but I can literally test & observe the exact same results by standing 2 screws on their heads 5 inches apart on my coffee table by putting a flashlight over the most southern screw.
      For an obelisk to cast no shadow, it means the sun was directly overhead the souther obelisk roughly noontime.
      For the sun to be that far south, indicates it is summer in Africa & winter in the north.
      Like I said though, you can recreate this exact effect on a flat plane, by merely putting the light directly over the most southern of the 2 screws, literally the exact same shadow effect, just without any curvature required to do so.
      If ya don't believe me, take 2 mins & do my expiriment yourself at home, you'll quickly find that very effect is 100% possible on a flat plane.
      Its just a matter of time of day & the season of year & the objects positions in relation ti the suns position for that tine of year

      Here's a good experiment then to prove your theory. Go research how far apart those 2 obelisks were those hundreds of years ago, and figure out how close the sun would have to be to have that same effect, based on the recorded shadow lengths. You could even recreate the experiment pretty easily with smartphones and a friend in another city, along with two tall objects of the same height if you can't find the data. How many airplanes and satellites would fly over the sun if you were right? I thunk the answer would blow your mind.
      Another question this brings up. If the sun is that close what is it? How does it produce energy? What keeps it from falling down?
      How does it light up the moon without being visible to us for periods of time at that distance? How common would eclipses be according to your model and your prediction of the distance to the sun?

Like I get people who lack basic critical thinking skills often try to claim the moon landing was fake because they feel intellectual insecurity and want to act like they can know something without doing the leg work. It was very interesting though. The moon landing was a "mass effect" in the sense that it advanced computer, communication, and material sciences forward by nearly a hundred years. I always find it funny when someone claims the moon landing was fake from a smart phone. To go through life with eyes so thoroughly shut is saddening.

You'll have a 100% change of heart if you ever humble yourself enough to hate your slavery to sin & meet your Maker (CHRIST) or at The Judgement Day, when you're held accountable for your wicked sin, if/since you chose to stay in your sin. I'll see you there, either way & you WILL remember THIS interaction of fair warning (because it's from your Maker, that I tell you ...& anyone who reads this). So, don't think, for one second, that your choice to stay in ignorance, will get you OUT of ANYTHING. IT WON'T. ALL of your sin goes on record for The Judgement. Just like in our justice system, ignorance is NO EXCUSE. You WILL reap what you sow & the Creator Savior GOD judges, based on HIS high standards, not lowly wicked ones. You'll definitely see that. The wages of sin IS death to ETERNAL Hellfire damnation punishment suffering, given by our Creator, The Judge, at The Judgement. You KNOW you're a sinner & you CAN'T stop (you're a slave to it). ONLY CHRIST can save ANYONE. He saved me, so I ALREADY KNOW (it's no "fairytale") & your ignorance & false witness opinion to state, in GROSS ignorance, that our Creator is a fairytale, is plain IDIOTIC ERROR & blasphemy. Your lack of awareness because you want to think that YOU'RE GOD & do your own thing (thinking you'll get away with it), doesn't make it so OR cancel the reality of GOD & His Almighty power to save & punish people. The Judgement IS coming. I hope you wake up BEFORE it's too late. You WILL remember my informing you & recognize me, when we gather before Him for The Judgement. I hope it will be because you became Saved. ETERNAL Hellfire suffering is no joke. There's NO escape (ALONE IN SUFFERING REGRET, IN PURE AGONY, for staying in such prideful stubborn UNgodliness. You have NO idea of the danger that you're in, for your sin. ...but you WILL, because that's what happens when people don't surrender, repent & seek CHRIST with your WHOLE HEART & let Him save & change you (set you free from your sin). ...but that won't happen, as long as you like & choose to hold to your sin (which makes people unrighteous & enemies of GOD). CHRIST saved me on 10/26/10, while I was desperately reading John 7:37-38 KJV & it was THE BEST DAY EVER! Your false witness can't UNdo my born again Salvation transformation EVIDENT PROOF testimony. I'm HERE & everyone saw my complete transformation. It's ALSO on record, to be my EVIDENT PROOF to keep me from being judged, at The Judgement Day, while EVERYONE watches EVERYONE ELSE BEING JUDGED. Can you imagine? Makes a court date here, seem like a celebration. It will not be a good day for most because they ignored, denied & rejected our righteous, Awesome Creator Savior. HUGE error. Tragic. I hope you will figure it out. It's coming, regardless. No one can overrule our Creator. Think about it. EVERYONE is going to be held accountable, UNLESS they're saved (changed to RIGHTEOUSNESS). He does it. Be encouraged. I was a wicked bartender (that's a legal drug dealer, in reality of our wicked low standards) & absolutely BURIED in my sin (multiple). If He can save me, He can save anyone. Some people simply AREN'T GOING TO BE HIS, BY CHOICE. TRAGIC, inDEED. I hope He saves you, regardless. Blessings in FOLLOWING CHRIST BEFORE it's too late.

      More than just 'common sense' they put in the effort to make observations and test them. Flat Earthers make no efforts for the most part, and when they do, it tends to backfire
      e.g Bob Knodel spending $20,000 to buy a laser gyroscope that proved him wrong, Jeranisms experiment proving him wrong.
      There's even a guy further down the comments here arguing for a flat Earth... he made a video of a flight he took from Melbourne, Australia to Santiago, Chile... and of course, his video shows him recording the ice of Antarctica out the window. On a flat earth that flight would have to go North, past Hawaii, the west coast of the US, Mexico, Peru and approach Santiago from the north.
      The psychology of these loons can be fascinating at times, other times hilarious and other times just sad.

The critical variable missing from this equation is the distance of the light source from the ground: again, a simple right angled triangle can explain this: the two poles being the two base points, and the light source being the single point on top. If you have the single point on top not too far off the base points, the hypotenuse represents the sun ray towards the opposite base point: this means the point directly below will see no shadow, and the other base point will produce a shadow.

    Some of these comments need to be addressed.
    1. The obelisks are just being used to demonstrate the concept.
    2. It was already known that in the southern town objects cast no shadow at midday on summer solstice.
    3. The scientist in Alexandria knew that objects cast a shadow everyday even on the summer solstice. All he did was measure the shadow.
    4. Then he got a man to measure how far the southern city is.
    5. He came up with a range of the size of earth based on his measurements which were in part estimates. He knew his methods were not precise.
    6. The circumference of the Earth fell within his range.
    7. Specifically, his low range estimate was within 100km of the actual circumference of Earth.

      Go out on a fishing charter for deep sea fishing.
      Take a telescope and try to locate land when you get to the destination where the fish are.
