If was gonna show sun rays coming through clouds and the rays create angles greater than parallel, would the sun have to be bigger or smaller than the distance between the holes in the clouds?
@@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.

Then the day after they would all return to the meeting point and report to each other what the shadow was when they measured it the previous day. Ok?
@@_I__AM__GOD_ Nope, you are wrong. What you say would be the case if the two different locations were separated in an East-West location. But in this case they were separated only by a North-South location which means the sun was at its peak at the same time at both locations. Get it?
@@_I__AM__GOD_ It would be the same time at each location and the shadows would be towards the exact same direction (north), but the length of each shadow would be different. Specifically, the shadow at the southern location which is closer to the equator would be small, while the shadow at the northern location which is farther from the equator would be longer, thus proving that the earth’s surface is curved, ie. round.

@꧁༺just another guy༻꧂ ok so you think they couldn't just go over to the other obelisk and observe the same thing. It's very simple and there's many extremely simple explanations as to how they did it. Just think.
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.
Isn't it amazing how with just an inquiring mind, observation, math and little legwork, a person living over two thousand years ago could (to a fairly accurate degree) determine the size and shape of the Earth? We owe so much to the brilliant and entrepreneurial minds that came before us.
@@beaver_warrior uh...no...he didn't have the slightest clue how big the earth was... Do you know why America was named for Vespucci & not Columbus? Because even after "discovering" it Columbus made 3 return trips back & forth... & still thought he was in India (or had discovered some uncharted islands off the coast of China of Japan)... That seems to indicate he didn't have the slightest clue about the actual circumference of the Earth if he was that far off. Vespucci went there once...did some simple star chart readings...discovered he was seeing star constellations that couldn't possibly be seen at the time of the year when he was supposed to be in India...& was the 1st person to come back & inform everybody... "Hey...this isn't already charted & divided up land (as by that time most of India had already been exploited by all the other countries occupying it)...this is a whole new world & completely conquerable w/out any fear of breaking treaties we have with all the other factions that have a claim to the already divided up India...come & rape it for all it's worth"... Instant Rock Star 🌟 Benjamin Franklin is considered the 1st Rock Star after inventing the lightning rod so people could build structures (as high as they wanted) w/out lightning taking them back down to the ground...but the original rock star was the man who came back from America & 1st announced that there was a whole new continent to conquer... 1st guy (well...a guy anyway...maybe not the 1st) to map it out named it after him (latin version of his name) on his maps.
@@chaosh7040 He said that scholars at the time knew, not Columbus himself. Columbus was bold but dopey, as you point out. Scholars like Vespucci knew the globe’s size but had no idea that there were two huge continents halfway between Europe and East Asia, assuming the space between to be open ocean. Columbus’ accidental discovery alerted them to the New World’s existence and then it was off to the races.
It’s amazing how he PROVED it too. He actually hired a group to count the distance as exactly as possible. Hundreds of miles. He used that information with cardinal directions to determine longitude and latitude; and the distance to the center of the earth. With this info he discovered the formula that showed the size of the earth and how to determine the time anywhere else.
I'm not a flat earther, but I question how they knew the length of shadows at a great distance from each other at an exact same time in those days of no immediate communication at a distance.
@@dyce100 with waterclocks and sundials? I realize they were scientific for the times, and have no doubt they could prove it, but it must have been no small task at the time to do so.
@@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.
Eratosthenes also calculated the Earth's circumference by measuring the difference in the two shadows, and was within the margin of error of the modern known measurement.

@@WildLifePrime there isn't a lack of parallax. It's just so hard to detect because of the vast distances in space, that it couldn't be measure until the 1830s. You have to understand that the maximim parallax cam only be ~2AU because that's the diameter of Earth's orbit around the sun. The next star is Proxima Centauri which is 4.2465ly away. That's 134280 times the diameter of Earth's orbit. The angle of parallax would only be 0.0000000902° You can't detect that with a normal telescope. You can calculate the angle yourself by the following formula: γ = 180 - 2 * atan(2h/a) Where h is the distance to the star and a is the diameter of Earth's orbit

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

@ptek69 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?
I will also add, if anyone was wondering, that he saw both the shadows at the same time by looking at the shadow in one place in one year and then looking at the shadow in the other place at the same date the next year.
had to scroll way too long to find someone else thinking about this. So it was the difference in shadow caused by differences in the latitude? If they were both measured at noon local time on the same day of the year? Also, though flat earthers are beyond any doubt wrong, they can sort of explain away Sagan's argument by saying the sun is actually very close to earth. It's a bizarre explanation, but flat earthers are aware of time zones and sort of account for them lol.
@@jettcaa year later it still is noon at 2 places 800 miles apart with no clock . Light houses is about the only way . Or 1600 messengers with flags spaced every half mile .

But didn't they use the sun to tell time back then? Wouldn't that throw off the measurement? How does he know that he's making his measurement at the exact same time?
@@ThinkitThrough-kd4fn him using the sun to tell the time did throw the calculation off by a little bit, but ONLY a little bit. I think it was only around 8 kilometers off, and they did have callendars back then so he could tell exactly what day he needed to be there
@@ThinkitThrough-kd4fnexcellent question. I think someone above has given a good answer. They would do the measurement at Noon At noon, the sun is at its highest, and there's no shadow to the east, and no shadow to the west. But there's some shadow to the north (if you're north of the equator). The further north you go, the longer the shadow-to-the-north would be
Just read the start of "The Demon-Haunted World: Science As A Candle in the Dark" and you learn how much sympathy and compassion he had for people who were fooled by the charlatans. And how much anger and indignation on their behalf, that so much misinformation was out there and treated as if it were real!
That's Hindi or other modern Indian language, though it was borrowed from the Sanskrit *bhūgola(m)* without the ending, as are all learned Sanskrit borrowings
The reason why the post at Syene didn't cast a shadow was because it was very close to the Tropic of Cancer. On the summer solstice in June, the sun is directly above the Tropic of Cancer, which is 23 1/2 degrees north of the equator. The post at Syene was only one degree of latitude north of the Tropic of Cancer at 24 degrees north latitude.
I mean... that is a valid point, for this one experiment. The earth is a globe, because the 29,957 other experiments together all point to a globe model. It's easy to pick on individual points, but it's the overwhelming force of the accumulated data which is the strength of the model.
@@bradleyakulov3618 i’ll always remember that vid of flat earthers doing an experiment to prove the earth is flat and they realise it’s round. Truly an anime moment.
Problem being, given when this occured while sun was at the tropic of cancer (according to globe literature) it actually ironically supports the flerf map as well given their accounts of the suns movements in seasons. You wind up with the exact same shadow effect, given the suns position for both sides of the argument, ironically unintentionally supporting the Flerf map, while disproving neither globe or flat earth model
They then took the difference in angles of the 2 shadows and took into account the distance between the 2 cities and came up with the 1st accurate measurement of the circumference of the earth.
How did they figure out that it was the same time in both cities so they could measure the shadow? I'm guessing their iPhones and Rolexes were down at the time
@@meyman9 yea. They noticed shadow was zero degrees in one place at noon and another city ( known distance away) at noon they noticed the shadow was like 7 degree difference. They assumed the earth was round since all heavenly bodies were and knew that it had 360 degrees. So if the cities were 500 miles apart and the sun at noon casted a difference in shadow of 1/50 (7 degrees) they took the distance multiplied the change over it and deduced the earth has a circumference of 25,000 miles which is very close to what it is.
@@colombianking no, you're explaining the actual calculation that Eratosthenes did to calculate the circumference of earth, that part is easy to understand, I was asking about something else that I guess other people don't think about. What I couldn't understand and looked up just now is how they knew when it was noon in two distant places on earth, their Seiko watches were down I assume 😉. What I didn't think about is that sundials are pretty exact but only to that exact place on earth, so it had to be two different but pretty accurate sundials to show exact noon in both places.
Eratosthenes THEN measured the distance between the two cities and, knowing the angular difference between the two, was able to multiply the distance between the two cities times the proportional angle in relation to a circle and he figured out the CIRCUMFERENCE of the Earth !
They got round that by saying the flat earth is infinite and therfore there is no edge for the cats to push things over, one day they will work out the only shape that allows that to happen is a sphere 😂
Its called the eratosthenes method. I learned this in 9th grade algebra and was fascinated by it but didn't find out about the greek egyptian dude until later. You can measure the circumference of the earth very accurately with a light pole, its shadow, and some simple geometry. I had a great teacher that year

The video is a bit misleading. The Ancient Greek already knew the Earth was round, because they had observed a sunset. The experiment in the video was to determine the radius of the Earth, not to prove it is round. A local Sun would have similar shadow effects on a flat Earth.

Nah, pretty sure they would claim the sun was close enough to make that difference, But would ignore everything else about the sun, which would no longer make sense with this change.

You dont need to do this experiment on the same exact day on both locations, just needs to be the same time in a close enough day of one another to ensure same position of sun relative to horizon(no shift); and even if you wanted to do both observations on same day, someone else could make the observations on one, and you on the other one, then compare.

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. Mostly they are boring though... but when they mess up, it sure is a hoot to watch.
No scientists? - that's exactly what they were! And it's not like this was some disorganized rogue dude that was sponsored by his family - Greece (and Egypt, and Rome) had academies where people were sent to study arithmetics, logic, geometry, medicine.... They were totally scientists!
Because there isn’t one answer to this dichotomy. The alternative view would be that the sun is actually smaller and more local to the Earth. Creating a shadow out of locality.
I'm not a flat earth person but this example is terrible. If you put the paper flat, and then put a flashlight directly over one tower then one tower would not cast a shadow but the other tower would.
You can put a Flat Earther in space, in orbit above the Earth, and they'd find a way to claim it's trickery. Remember, Forest Gump's mother told us, "Stupid is as Stupid does."
Well most ppl couldn't even read back then so they probably wouldn't hate them as much as we do lol. At least ppl had an excuse to not know stuff back then. Current flat earthers have no excuse
A lot of people in the time back then were actually flat earthers. Yes, there were thinkers, who showed, that the earth is round, but have you ever looked at the world map of herodot, his world and the wolrd of greek mythology is flat, the continents surounded by the great okeanos.
Guy seems to have skipped trigonometry. Like this is super basic stuff. If you have a right angled triangle you can easily picture the same phenomenon on a flat surface.
Well duplicating the results for a flat surface is hardly the point … we need an example which results in obvious differences. I’m sure Carl Sagan had more than a basic understanding of 3 dimensional trigonometry - and 4th dimensional geometry. He might aim his explanations at the average viewer, but to explain things so clearly and unambiguously shows a much deeper understanding. My primary admiration is for Carl as a universal educator.
@@Xubono this is not "3 dimensional trigonometry" ... This is basic 2 dimension trigonometry ... 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. Again, this is basic trigonometry.
they didn't, they measured the shadow lengths at about the same time and then met up later. it would take several days or longer (maybe a week unless they traveled by boat) for one to get to the other but they had sundials so they could figure out relatively when to measure the shadows
The obelisks are the same height. Their shadows will be shortest around midday. Just measure the shadows at the shortest and you'll find the shadow of the obelisk further north never gets as short as the one from the obelisk pointing more directly toward the sun.
@@JasonBoyce but how did they measure at the same time? Like...how did they know it was 12 o'clock or smth? Shadow clock? Wouldn't 10 of shadow clock in point A be 12 at point B? I know, I could google, I'm too lazy
@@VajraSutra if it takes too long to get between the two obelisks, seasonal tilt of the earth might affect things. That’s what I was thinking. That and knowing when exactly is mid day.
You can literally just stand on the beach and watch ships disappear from the bottom up as they get further away. I basically grew up there. Its pretty easy to see the earth is round from even the ground. People are freaking nuts lol
He was always tripping hard. Dude loved his magick mushrooms.... Based on the above substantial evidence, how could it be? The ancient Egyptians can infer the only answer Carl Sagan not a only enjoyed 🍄 but ALSO listening 🎧 to *JOURNEY* . Simultaneously? Nobody knows ..
@@Nico-pl6sf according to every source that knew Carl Sagan he often enjoyed marijuana he even wrote an essay about it under a pseudonym. Nothing I have ever seen has even suggested mushrooms, it would be interesting to see who made up this ‘fact’
Flat earth theory assumes that the midnight sun occurs only at the North Pole, and that there is no such place as the South Pole. However, the South Pole does exist, and the midnight sun also occurs there, but on December 21, at the opposite time of year that the midnight sun occurs at the North Pole, which happens on June 21. The midnight sun's annual appearance at one pole, and at the other pole at opposite times of the year proves that the earth is round.
I mean, even if elon musk takes those flat earthers to the space to see earth with their own eyes, they would argue that the windows are fake. Take them outside of the spaceship, they would argue that the helmet glass arent real. Tell them to take off their helmet, they’re dead. Theres no winning with those guys.
It doesn't prove anything, the sun can be directly above on obelisk while shining on the other obelisk from an angle, this still makes sense with the earth being flat (which it is) and the sun moving around the earth in circles above
@@MF_JONES yes but using... angles you can tell how long the shadow should be depending on how its tilted and how far from the other obelisk is. Darn math.

@@BeyondBirthThey said “Hey, When your sun dial says this time, have your scribe write how long that shadow is, We’ll compare papyrus after” Did you think they had no concept for time back then? Or the ability to coordinate? XD
The excuse on this occasion has long been invented by adherents of flat earth. In their opinion, the sun is a few kilometers above the ground and flies in a circle. While the sun is over one of the obelisks, the shadow does not fall from it. And from another falls. The existence of the night is explained by other excuses.
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. I'm going off of memory, so please correct me if I'm wrong.
I've pointed out several times that they always neglect to inform the public of the difference in elevation. Alexandria sits at about 9 meters from sea level while seyen is at 190 meters in elevation. This reality alone should have put this theory to bed... sound asleep.

Carl missed the point. Back in ancient greek there were no telephones nor fast enough vehicles to compare the shadow lenghts in an acceptable time window. So his explanation here is based on anachronistic standards by not taking the available means of that time into account.
@@aladdin8623The moment, on the summer solstice, when the sun is at its highest elevation. The sun doesn't have to attain the same elevation at the two locations, in fact it won't: that's the point.

If was gonna show sun rays coming through clouds and the rays create angles greater than parallel, would the sun have to be bigger or smaller than the distance between the holes in the clouds?
@@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.

@@_I__AM__GOD_ Nope, you are wrong. What you say would be the case if the two different locations were separated in an East-West location. But in this case they were separated only by a North-South location which means the sun was at its peak at the same time at both locations. Get it?
@@_I__AM__GOD_ It would be the same time at each location and the shadows would be towards the exact same direction (north), but the length of each shadow would be different.
Specifically, the shadow at the southern location which is closer to the equator would be small, while the shadow at the northern location which is farther from the equator would be longer, thus proving that the earth’s surface is curved, ie. round.

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.
Isn't it amazing how with just an inquiring mind, observation, math and little legwork, a person living over two thousand years ago could (to a fairly accurate degree) determine the size and shape of the Earth? We owe so much to the brilliant and entrepreneurial minds that came before us.
I remember the story. Thank you for presenting it. You are a scholar and nobleman. 🫡

@@rogerthomas169I'm agreeing with you by the way 😅
Just adding to the questioning.
@@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.

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.

@@ThinkitThrough-kd4fn him using the sun to tell the time did throw the calculation off by a little bit, but ONLY a little bit. I think it was only around 8 kilometers off, and they did have callendars back then so he could tell exactly what day he needed to be there
@@ThinkitThrough-kd4fnexcellent question. I think someone above has given a good answer. They would do the measurement at Noon
At noon, the sun is at its highest, and there's no shadow to the east, and no shadow to the west. But there's some shadow to the north (if you're north of the equator). The further north you go, the longer the shadow-to-the-north would be

Problem being, given when this occured while sun was at the tropic of cancer (according to globe literature) it actually ironically supports the flerf map as well given their accounts of the suns movements in seasons.

They then took the difference in angles of the 2 shadows and took into account the distance between the 2 cities and came up with the 1st accurate measurement of the circumference of the earth.
How did they figure out that it was the same time in both cities so they could measure the shadow? I'm guessing their iPhones and Rolexes were down at the time
@@meyman9 because everyone knew when the sun is straight up its noon in both places.
@@colombianking but they could tell it's straight up if they used shadows to tell it's straight up
@@meyman9 yea. They noticed shadow was zero degrees in one place at noon and another city ( known distance away) at noon they noticed the shadow was like 7 degree difference. They assumed the earth was round since all heavenly bodies were and knew that it had 360 degrees.
So if the cities were 500 miles apart and the sun at noon casted a difference in shadow of 1/50 (7 degrees) they took the distance multiplied the change over it and deduced the earth has a circumference of 25,000 miles which is very close to what it is.
@@colombianking no, you're explaining the actual calculation that Eratosthenes did to calculate the circumference of earth, that part is easy to understand, I was asking about something else that I guess other people don't think about. What I couldn't understand and looked up just now is how they knew when it was noon in two distant places on earth, their Seiko watches were down I assume 😉. What I didn't think about is that sundials are pretty exact but only to that exact place on earth, so it had to be two different but pretty accurate sundials to show exact noon in both places.
Eratosthenes THEN measured the distance between the two cities and, knowing the angular difference between the two, was able to multiply the distance between the two cities times the proportional angle in relation to a circle and he figured out the CIRCUMFERENCE of the Earth !

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.

Btw as for how they ensured they did the measurements simultaneously, they had timekeeping devices called water clocks (very similar to hourglasses) in Egypt as early as 1600BC, so they could start their water clocks at the same time, at the same place, one person goes from one city to the other, and they measure at a predetermined time.
Plus sundials. Compared to clocks, sundials aren't that accurate.

Just curious, how did ancient people observe both shadows at the same instance?
You dont need to do this experiment on the same exact day on both locations, just needs to be the same time in a close enough day of one another to ensure same position of sun relative to horizon(no shift); and even if you wanted to do both observations on same day, someone else could make the observations on one, and you on the other one, then compare.
You agree on a day & time (noon) for the observation well BEFORE the observation day, and compare your results AFTER it.

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.

I’m sure Carl Sagan had more than a basic understanding of 3 dimensional trigonometry - and 4th dimensional geometry. He might aim his explanations at the average viewer, but to explain things so clearly and unambiguously shows a much deeper understanding. My primary admiration is for Carl as a universal educator.
@@Xubono this is not "3 dimensional trigonometry" ... This is basic 2 dimension trigonometry ... 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.
Again, this is basic trigonometry.
What I want to know, is how they compared shadows in real time at that distance.
they didn't, they measured the shadow lengths at about the same time and then met up later. it would take several days or longer (maybe a week unless they traveled by boat) for one to get to the other
but they had sundials so they could figure out relatively when to measure the shadows
The obelisks are the same height. Their shadows will be shortest around midday. Just measure the shadows at the shortest and you'll find the shadow of the obelisk further north never gets as short as the one from the obelisk pointing more directly toward the sun.
@@JasonBoyce but how did they measure at the same time? Like...how did they know it was 12 o'clock or smth?
Shadow clock? Wouldn't 10 of shadow clock in point A be 12 at point B?
I know, I could google, I'm too lazy
@@VajraSutra if it takes too long to get between the two obelisks, seasonal tilt of the earth might affect things. That’s what I was thinking. That and knowing when exactly is mid day.
They make a call😂
You can literally just stand on the beach and watch ships disappear from the bottom up as they get further away. I basically grew up there. Its pretty easy to see the earth is round from even the ground. People are freaking nuts lol
I miss Carl....he would be tripping hard in today's complex world we are marching to nowadays...God Bless him and his JOURNEY..
Wait, wasn't Carl an atheist?... Now, in the other world(astral), he is no more...😅
He was always tripping hard. Dude loved his magick mushrooms....
Based on the above substantial evidence, how could it be? The ancient Egyptians can infer the only answer Carl Sagan not a only enjoyed 🍄 but ALSO listening 🎧 to *JOURNEY* . Simultaneously? Nobody knows ..
@@Nico-pl6sf according to every source that knew Carl Sagan he often enjoyed marijuana he even wrote an essay about it under a pseudonym. Nothing I have ever seen has even suggested mushrooms, it would be interesting to see who made up this ‘fact’
@@arjunadan3812 I think so, yeah, a shame someone this smart couldn't discover the most important truth of all
It's amazing ancient Greeks invented teleportation to discover that the earth is curved.
I guess thats how they managed to be in two places at the same time to see the shadows. Ha ha.
It actually more amazing that modern people have forgotten how to talk and arrange to do something in two different places at the same time.
No need for sarcasm, they could discuss it on the phone as well..
ruclips.net/video/laXhTcko-lg/видео.html this might interest you guys
@@xerex21212 it amazes me how people think shadows of different lengths cast by giant sundials signify the same time of day. pillock!
Carl Sagan, the legend in the language we all know and love
With that analogy my logic tells me that Trumpists are an impossibility but they still do exist!
You mean the same guy that got bought out by the govt to also dispell the thought of other life in the universe due to UFO hysteria?
Your a joke
Flat earth theory assumes that the midnight sun occurs only at the North Pole, and that there is no such place as the South Pole. However, the South Pole does exist, and the midnight sun also occurs there, but on December 21, at the opposite time of year that the midnight sun occurs at the North Pole, which happens on June 21. The midnight sun's annual appearance at one pole, and at the other pole at opposite times of the year proves that the earth is round.
Oh nooooooo, a 40 second video proving wrong an entire group of flat earthers
I refuse to believe flat earthers are anything more than trolls.
I mean, even if elon musk takes those flat earthers to the space to see earth with their own eyes, they would argue that the windows are fake. Take them outside of the spaceship, they would argue that the helmet glass arent real. Tell them to take off their helmet, they’re dead. Theres no winning with those guys.
It doesn't prove anything, the sun can be directly above on obelisk while shining on the other obelisk from an angle, this still makes sense with the earth being flat (which it is) and the sun moving around the earth in circles above
@@MF_JONES yes but using... angles you can tell how long the shadow should be depending on how its tilted and how far from the other obelisk is. Darn math.
@@Time-yo5mw you don't know what you're talking about. And I'm just using... Simple logic
The Greeks forgot to send the memo to the flat earthers
Carl Sagan, battling flat earthers from the grave. I salute you
Yelling across the desert:
"Do you see a shadow?"
"No! What about you?"
"Yep!"
"WTF?"
2000 years ago this experiment was difficult to perform, but they managed. Today we all could do it in a hearthbeat, but people choose not even try it and make crazy theories instead. Sad how much we devolved...😔

I met Carl Sagen when I was in grade school. It's something I will never forget! Carl Sagen really was a national treasure. I wonder what he would think of our world today. 🌎
He'd be woke as hell. Stone cold bleeding heart back in the day.
@@BiffJackson-o4iA good man.
Yeah but only if you remember that 80s was just as crazy. You just look back the time through rose tinted glasses. And when you ask older generations they would say the same thing about 80s back then like gen xers do now.
He was Satan incarnate. A very bad man 😔.
He would be thinking, ‘is that a man or a woman’?
Ah, yes. The Ancient Greek. He was a cool guy.
Even got his own yogurt

The late, great Carl Sagan. I loved watching him as a teenager and learnt a lot. Sadly missed.
Learned*
I do not apologize.
My buddy in High School introduced me to him. We watched him all the time. Good memories.

But no flat earther ever does
They totally should
Yea, genius, and how did they do it back then? Riddle me that. Sagan was a scam artist.
@@BeyondBirthThey said “Hey, When your sun dial says this time, have your scribe write how long that shadow is, We’ll compare papyrus after” Did you think they had no concept for time back then? Or the ability to coordinate? XD
@@BeyondBirthSimply measure at noon. (Shortest shadow) One location is further North.
The excuse on this occasion has long been invented by adherents of flat earth. In their opinion, the sun is a few kilometers above the ground and flies in a circle. While the sun is over one of the obelisks, the shadow does not fall from it. And from another falls. The existence of the night is explained by other excuses.
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.
I'm going off of memory, so please correct me if I'm wrong.
I've pointed out several times that they always neglect to inform the public of the difference in elevation.
Alexandria sits at about 9 meters from sea level while seyen is at 190 meters in elevation.
This reality alone should have put this theory to bed... sound asleep.

@@christophersharpe2555 plenty of examples of curved water. A drop of water. Pour water into a glass and it curves to fill the glass. Put a curved object in water so it displaces the water and the water curves around the object.

yet too goofy to realize a local sun could explain this.....when i look at the sun it doesnt look 3 trillions nonsense...men tell you that and you do cause others do....we call that being an NPC in 2024
Carl missed the point. Back in ancient greek there were no telephones nor fast enough vehicles to compare the shadow lenghts in an acceptable time window. So his explanation here is based on anachronistic standards by not taking the available means of that time into account.
1 in a million would equate to over 8 thousand Carl Sagans right now..
@@aladdin8623The moment, on the summer solstice, when the sun is at its highest elevation. The sun doesn't have to attain the same elevation at the two locations, in fact it won't: that's the point. But it will be at its highest elevation at both places at the same time.
