10:15 um actually Dan, the orbit around the sun does affect the day somehow, I am not guru on this but Equation Of Time is a thing. en.wikipedia.org/wiki/Equation_of_time Wally
None of the times based on celestial objects are perfectly aligned - the Moon being the most obvious given Lunar calendars get out of date real quick. The question is how much of a difference any of this makes - clearly the smaller the difference the less apparent this is. The speed of rotation of the Earth is actually slowing down as well as the revolution around the sun. That means days and years are getting longer - so would actually line up at some point after we're all dead.
@@deusEXmachinaV42 In my other comment I looked up the different orbital speeds and they vary by about 10% between the extremes. So +-5% Though keep in mind that's 5% of those additional 4 minutes per day so just about +-12 seconds in total
The definition of the hour is 1/24th of the *mean* solar day. With the fact that sunrise and sunset times are varying seasonally, the average (excuse the pun) person wouldn't be able to tell that individual solar days vary in length.

I told this theory to my cat. She just looked at me, shook her head and went to her experiments on gravity. Knocking another item off my desk. I know she has done that experiment before but science has to be repeatable, and as all cats are world self proclaimed sceintist, they will continue to test their gravitational experiments as long as I keep putting items on my desk she can knock off. This proves cats understand science better than all flat earthers.
Cats are indeed a useful bit of kit when it comes to explaining a globe earth rather than a flat one. If the earth were truly flat it would just be a flat disc with nothing at all on it. After all these millions of years cats would by now have knocked everything off the edge.

No possible way this guy is for real at this point. It has to be an act. He just flat out ignores every counter-argument. He doesn't acknowledge them at all, he just puts out absurdly wrong arguments and then runs away.

Honestly I think this is the least confusingly stupid thing flerfs have ever come up with. With this, you can _understand_ why they're misunderstanding reality. Usually it's complete squirrrelshit nuttery all the way through, but he's _partially correct_ with this and doesn't know it. Day and night do "switch places", it just doesn't matter because he misunderstands what a 'day' means and how long a year is, how insignificant the change is from day to day, and that we live in a 3D universe, not a 2D flatbrain flerf fantasy world. So nothing new, really. I think he just tripped and fell accidentally close to making an actual point. Chalk it up to statistical error. A child could understand why he's wrong with minimal explanation, but a child might wonder the same thing. If this is progress, and not dumbfuckery accidentally approaching a (1) wit, then in a few decades flerfs might ask an interesting question that doesn't induce lethal facepalming. Maybe. Optimism, ho!

He simply doesn't know that there is a well-known difference between rotation duration and day duration. And everybody who "does his own research" can easily find this out within minutes. At least if you don't do your research completly on flattard youtube channels......
Yeah, because that's the place he wants to make his return. Great memories. He would, probably, fly there, because what could bring back warm fuzzy memories like a flight to the grassy knoll.
Some people will accept being a 'big fish' in a VERY small pond, because they don't have what it takes to be a 'big fish' in the very large, real world.
I’m pretty convinced, after this, that Eric is just a conman. Over time he’s just used to treating his followers like mugs but knows how to speak to them in a way they’d believe him. No debates, no live interviews. For such a revered flat earther, he’s very shy of interaction, and we can all guess why. Thanks Dan, I always feel better about myself every Tuesday and Friday!
Dubay has ALWAYS been a conman from day one. I've been shadow banned on so many of his videos I lost count! He can't stand confrontation and doesn't want any of his disciples to see it either.
I think at least some Flefers are con men who just promote this rubbish for views and selling merch. Sadly some are genuine. These genuine belivers must rank among the least intelligent people on earth.
Eric is dishonest and knows there are stupid people enough to follow him. He is a big fish in a very small, shallow and drying pool. Too bad the other fish are spawning like rabbits.
He is not really stupid. Granted he's not exactly the sharpest tool in the box since all of his 'proofs' are very easily shown to be claptrap by anyone who cares to do so, but he was smart enough to know that spouting idiotic stuff to gullible fools who will swallow any old crap without bothering to investigate them since it makes them feel special, would be a moneyspinner.
I have a JEHOVAH's witness background. They fully accept the heliocentric model and have no problem with big bang cosmology. But the bible stuff they claim to believe is quite insane. Are they, or maybe more accurately the leaders, stupid or dishonest? Bob the Science Guy is working on a series on the psychology of science deniers. I've read some books on why people believe stupid things and develop cultlike adherence to bad ideas. Still trying to work through it all. My ex got so involved in conspiracy theories and craziness she eventually went quite paranoid and irrational, where anything you'd explain to her she'd twist it 180 degrees in her mind. She was more into hollow earth, not flat, though.
He is immediately wrong in the phrase: "[according to the globe theory] ...Earth makes one complete rotation on its axis every 24 hours." No, no it doesn't. It makes one complete rotation in 23 hours and 56 minutes (sidereal day). It takes an additional four minutes (approximately) for it to rotate to face the sun precisely, due the movement in orbit between one day and the next. (The four minutes is approximate due to the eccentricity of earth's orbit and the vector addition of its tilted rotation with the orbital motion.) Since we keep time according to mean solar days, not sidereal days, the sun is never going to be on the other side of the globe at local noon. The difference between mean solar time and local sun time (sundial indication) has been known since accurate clocks were first made, and is called the "equation of time." So, he's wrong again when he says solar days are exactly 24 hours long. No, their length varies throughout the year due to the varying orbital speed and relative tilt.
Well written! I've seen Eric Dubay run this "argument" several times before. He basically swaps the definitions of sidereal and solar days, then claim it leads to contradictions. That is indeed true, misrepresenting definitions does lead to inconsistencies.
Also, his statement looks like he took something, let it be wooden bar with length of 1 meter, measures it and says - "hey, its length is 1 meter, what a coinkidink!". But it is MADE SO. People MADE timescale to fit it to day and night, to make it useful. Gosh.
SciManDan, I can't believe you had had to say out loud, “the daytime is always going to be the part of the earth facing the sun.” I laughed out loud hearing you say that out loud. 😂🤣😆 That was a good laugh to start my Friday.
I love the fact that one of his arguments against a globe is that Earth must speed up and down, when we globe-earthers have been pointing out over and over again that the sun must do the same if the flat earth model shall have any chance of explaining the seasons.
Yes, the Sun needing to "change lanes" between the Tropics of Cancer and Capricorn, which on the Flat Earth diagram (no model, so they say) would require speed changes to maintain the same time per rotation around the North Pole axis.
The issue is that the radius and the speed change are opposite in those two scenarios. On FE, the larger radius must go faster to keep the day at 24 hours. With earth's orbit, as the radius reduces as we get to the perihelion, and consequently speed up. One of these makes sense in physics.
@@Ravaxr I wonder what they think would be the reason of the sun speeding up.. I would guess "Because mah God". It's always the argument that can't be disproven as God just is un-falsifiable... :/
I know, I couldn't believe what I was hearing. He was like "It's a problem for the globe model because the sun would get 180 degrees out of sync with clock time" but then actually accepts that there's a difference between the solar day and 360 degree rotation day and COMPLETELY FUCKING FAILS to put two and two together to see he has exactly what he was looking for to solve his stupid "paradox". I can't understand how you fail that badly. It's not like other flat earth nonsense that's just denying reality. He explicitly accepts the key fact, and completely drops the ball on understanding it.
It's bizarre that he knows time is based on the solar day, not sidereal one, forcing noon to be when the Sun is highest, yet can't understand time was invented to be independent of the sidereal day.
My guess is that he well understands it. Its just his usual blablah in order to fool the fools. I don´t really know what for, but it has something to do with fame in his own little bubble.
He somehow thinks the sidereal day is the one the clocks keep track of. That's kind of amazing because he's kind of right, if our clocks were set so a day is 23 hours and 56 minutes the day would drift out of track of the day/night cycle, the problem of course is no one other than astrologists care about the sidereal time.
The difference between sidereal and actual time could easily be overcome with a sundial. We would all just be on slightly different times globally. This is what makes his theory so preposterous.
They think that bc of the 4mins delay, there would be an inconsistent in sunrise and sunset (which does varied due to different reason so we can't see it without taking those reason into account (and no fking normal people take those reason into account when announce the sunrise and sunset time)) But I think that those delay doesn't happen 365 days a year, so 4 * 365 mins of delay calculation doesn't work. For very accurate measure of time, they did include these 4 mins and the prediction and stuff just match the reality to an extreme degree.
Interestingly enough, if you place someone underground with no sunlight and no clocks, their sleep cycle rapidly approaches the period of time it takes the moon to return to the same position _above the earth._ I hesitate to call this a lunar day to avoid confusing it with the period it takes the moon to rotate on its axis. One has to assume that this phenomenon is linked to the tidal forces generated by the moon.
Yes! I was going to make the same comment! The sidereal day ( the time for the globe to rotate around its axis relative to the stars) is only ~ 23 hours and 56 minutes but as the globe also moves around the sun it needs an extra 4 min to rotate around its axis relative to the sun. So that makes up for a complete year. Number of days in a year is 365 ==> 365 * 4 min = 1460 min = 24 hours . This very easy to verify for yourself which I did about 2 years ago. Take some pictures of the night sky and the stars from the same position and observe the positions of some bright stars relative to some building or trees some 100 meters away. If you take the pictures 1 week apart, you will notice a 28 minutes difference in time ( 7 * 4 min) for the stars to be in the same position. Easy!!
It doesn't even need a 3d model. You can see it in a 2d model of the rotations. The "day and night would flip" he is referring to, DOES HAPPEN. That roughly 4 min difference between the two "days" adds up to 12 hrs over the course of half a year. If you just draw 2d circles on a paper ad make a tic mark on the earth to show it's 360deg rotation point as "noon", yes, by the time it goes through half a year that sidereal day returns to it's position on the page at midnight on the other side of the sun. He is right about that. But it's because of that 4 min difference - do the math- 12 hrs in half a year. That's why we see different stars in the winter than we do in the summer. The sun and stars don't move (relative to a year), the earth rotation and the "problem" he is highlighting explain why we see what we do. It comports with observable reality.
@@militaryartandscience But why is it that it's exactly 12 hours over half a year and 24 hours over a year? COINCIDENCE?? I THINK NOT!!11! /s For real, the problem is exactly that, I think this is a perfect example for this kind of fallacy: most seem to come from a biblical viewpoint, where things like days are defined by god, and then you'd apply those terms to scientific models and find coincidences all over. And I get it, if you think of 1 day as 24 hours and then looking at the globes "supposed" movements, his explanation seems logical. Until you realize, the earth was here long before humans existed, an hour is just an arbitrary measurement, 1/24 of a day, and a day was defined by humans in ancient times as "sun down, sun up again". And that day therefore INCLUDES the rotation around the sun and all the stuff that's been already going on for millions of years (I know, leap seconds, leap year...).
He doesn't realize that the clock was created to reflect the day and not the other way around. I see the hoops his mind jumped through to come to this conclusion, but that tiny bit of extra rotation that happens every day is already built in to our calculations of time. He thinks that the calculated rotation of the planet should be based on some universal coordinate system, and not on our own star. As anyone could quickly figure out, if they gave it some real thought, this is not only an improbable request, but highly impractical, and irrelevant effort for our daily purposes.
No, everyone knows that there's a great big grandfather clock in heaven that the Bible forgot to mention being created just before the earth was created at exactly 6 p.m. on Sunday, October 23, 4004 BC (Julian Calendar), and the length of the day was set to match two revolutions of this clock's hour hand. Didn't any of you people go to Sunday School?
I think that this is the crucial fact that Dan didn’t really explain to well. The solar day is the time it takes the globe to spin relative to the sun and we, ie humans, defined that as 24 hours long before the sidereal day was fully understood. But it is the difference between solar and sidereal that account for the ‘flip’ the earth makes in 6 months.
Imagine trying to explain Leap Centuries to Eric Dubay. Trying to explain a Leap Century to him, and how February 29th doesn't happen. How they only happen every 400 years. Lucky he was around for 2000 or he would be calling out the conspiracy theorists. Glad I wont be around in 2100 for that circus.
This is why I love flat earthers. They make these childish (in a good way) arguments that are clearly wrong but in trying to express precisely why they're wrong I always gain a deeper understanding of the topic.
I often find myself perplexed and cannot easily grasp what their globe debunk claim even is. I listen to their argument and usually it makes absolutely no sense to me. I have to try to block out logic and known facts to get a mental picture how their theory would work. Then I'm even more perplexed that they believe this theory despite it being so obviously wrong and a total contradiction of observed reality.
What is continually amazing to me, is that they have NO FLIPPING IDEA that astronomers throughout history have arduously PRE-debunked ALL of their "arguments" (which don't really deserve that term). I mean, THIS is THE poster boy example, of a dire attack by ignorant people thinking that they are the best thing since sliceable mayonaise... If ONLY they would use that energy against the BIGGEST science-deniers out there: ROTpublican Officials. But I am liking the dynamics of this "argument." One Ignorant Git claims some nonsense, and a couple dozen of us EDUCATED citizens have enough GOOD information handy (um, in our BRAINS), to debunk them even before we listen to Dan's arguments.
ED: "our 24 hour clocks, which billions of people have used for thousands of years... " Me before he can even finish that sentence: "nope, nope, nope, nope,... I know where you are going with this and that is NOT how it works." I lost count how many times I furrowed my brow in disbelief with this video alone.
Yup. The for thousands of years people have used exactly one clock.. the sun in the sky. And that clock somehow always matches the sun in the sky. Funny how that works, eh? 🙂
Actually flarf here is correct. If 24 hours equalled a 360-degree rotation, sunrise would slowly walk around the planet each year. However, 24hours doesn't equal 360 degrees; it's slightly more to compensate for the earth's rotation. (It's also not 24 hours exact, but you know). So yes, every 6 months, day and night flip. It just does so a little at less than 1 degree per day
I have the (silly) hobby to ask people if they'd like some recommendations; especially science-channel and such. Yeah, its random and i'm often called Robot for it, but who cares? I live for those few who say 'Yes thanks' (though No thanks is also nicer than calling me non-alive...) and i wont stop asking around. I wanna spread Education, so i recommend edu-channel, duh!
does he honestly think the fact that the day happens to be 24 hours is a coincidence? Like the clocks were made first and they just happened to match how long a day is? The day is what it is and we divided it into 24 hour long units for our convenience.
Probably. I mean they are all about "observing with your own eyes". Since they probably see a clock first and then that the earth is flat its probably how they put that together. They call it a "model" We call it "making it up as they go along"
Exactly. If the earth rotated exactly 2% slower than it does, every day, every hour, every minute, and every second would be exactly 2% shorter than they are. Those are all completely arbitrary units indexed to the length of one solar day. (Yes, I realize that the SI second is now indexed to regular fluctuations of the caesium-133 atom, but the constant that links these two things is also completely arbitrary and was set to make one second equal to one 86,400th of one solar day.)
our 'day' wasn't always 24 hours long. how people kept track of time throughout history has changed many times. it was especially bad during the dark ages when most people could not read or write... or count. since records back then were so poorly kept almost nobody knew what year it was, or which day it was.
I live in the Arctic circle. Luckily I get six weeks of night once each year and six weeks of day once each year. Created by a combination of axial tilt and the rotation round the sun. I also regularly see the auroræ Which follow the magnetic force lines , created by the earth spinning. When Eric accurately predicts these things with his model . I will listen, because he can’t I won’t hold my breath whilst waiting. Thanks Dan and keep up the good work.
@@manhhoang8389 i work nights so adjusting to being awake or asleep at weird times is a part of my daily life. When I first moved here though it was tough, especially no dark to sleep by. The long dark of winter is tiring, but you get used to it and in other ways it is a beautiful time of year.
6:01 I'm confused at Dan's rejection of Dubay on this point. Dubay says we use the ~4 minute shorter sidereal days to explain why day/night doesn't flip. Then Dan says "Nope. No one's saying that". But... isn't that exactly the right defense to use against Dubay's claim? Say you have a normal clock, and a sidereal clock. The "sidereal" clock runs 4 minutes fast. After 6 months, it will be exactly 12 hours ahead of the normal clock (4 min * 6 months = 12 hours). Dubay is pointing at a sidereal clock and saying "See! After 6 months, it's nighttime at noon and daytime at midnight!". So the appropriate counter is "But that's because the clock you're using runs 4 minutes fast every single day for 6 months"?
I really appreciate that Eric uses images of star trails in this 'presentation'. Perhaps he could look at two side by side, one taken from anywhere in the northern hemisphere and the other taken from the southern hemisphere. If he did and was paying attention he would note that in one of them the trail moves clockwise and in the other it moves anticlockwise. Maybe he could then go on to explain how, on a flat earth, people in Europe or North America see the stars moving in one direction whilst simultaneously people in Australia or South America see the stars moving in the opposite direction. Perhaps he could build a model to demonstrate this amazing phenomenon ......... or there again, maybe he couldn't.
And how people in South America and Australia, can look in opposite directions and see the same stars at the same time to the south. Very difficult on a flat earth.
@@grahvis Or how it can be that everybody north of the equator can see the star Polaris but nobody south of the equator can. What is so frustrating is that all of these flat earthers know these things, they know full well that they are impossible on a flat earth yet they simply ignore it and still persist in peddling this rubbish.
Yes, the existence of two celestial poles of rotation, South and North, is impossible in the usual flat Earth model, but has been well known for a long time and is documented in many photographs,
While he's at it, can't he make a modell where the stars rotate in a circle instead of in an elliptical pattern on a flat earth model on any other place than the north pole. I won't hold my breath...
"The earth makes a full rotation every 24 hours ..." is wrong. The length of a full rotation is a bit more than 23 hours 56 minutes (sidereal day). Every 24 hours it will face the sun at around 12 o'clock (solar day). No night and day flipping required.
Exactly - and that's what they mixed up and that's where this misunderstanding comes. Imho this is the best observation I've ever seen from a flat earther. The thing is: they should've look into it a bit deeper, instead of thinking everybody missed this hole in the globe Earth model...
It's also important to point out that the solar day is ON AVERAGE 24hrs, but it does change through the year due to the elliptical orbit. This is part of what causes the analemma
@@isuller I thought so too for the first half of the video, but then ED out-did himself by showing that he actually knows about solar and sidereal days, but "it's a lie".
Eric's argument works, because he gets one thing fundamentally wrong. The Earth doesn't spin on its axis in 24 hours, but in 23 hours, 56 minutes and 41 seconds. It takes 3 minutes and 19 seconds more to face the sun because while it's rotating on itself, it's also revolving around the sun. He's using solar days as sidereal days.
@@yahschild9348 I don't think you understand the difference between a sidereal day and a solar day. Let's start a high noon. 23 hours and 56 minutes later, the earth has made a full rotation (a sidereal day). However, the sun is 4 minutes away from the next high noon, because in that time the earth has moved along its orbit. The earth needs to rotate roughly 361 degrees which takes another 4 minutes. This gives us a solar day of 24 hours. Since the solar day is built around the sun returning to the same point, our clocks remain accurate.
It still cracks me up when flerfs cite Dubay for anything. He's the most thoroughly debunked flat earther in existence. It's like citing a bottle of Evian as proof that water doesn't exist.
lol good analogy. I think they love that his voice drips with the most punchable blend of "condescending wanker", "arrogant jerk" and "self-righteous sanctimonious prick" I've ever heard.
@@Wolfie6020 I've used your videos numerous times debunking flat earthers and they all either run away or they say " Fake, Dubay has debunked that!" Hilarious!
He clearly understands the difference between the sidereal day and the solar day. He knows that the stars seem to move faster than the sun. His explanation proves of the heliocentric model, so it's funny how he comes to a different conclusion. In fact I would say it's one of the best proofs for heliocentrism and round earth.
He's overthinking things, and he forgot the clear thing that a day is 24h because that's just how we decided it is, not because we created the model and based all our timekeeping on it.
That seems to be the way a lot of the "proofs" go. They look at something that clearly indicates our actual globe, spinning while orbiting the sun, and say "See!!! FLAT EARTH!!!" :D
He understands those two differences, but comes to a different conclusion to literally everyone else because he is utterly convinced for absolutely no reason that the Earth is a fixed point in spacetime and the entire universe revolves around his tiny little brain... It's hilarious really...
And the funny thing is that he didn't do his calculation of day / night flipping with the sidereal day. As the sidereal day is 4 min shorter than solar day, you accumulate about 12 hours difference over 6 months. So day and night do shift places if you count days on the sidereal calendar.
Eric says we "suddenly claim the earth rotates 23 hours 56 minutes" and that nobody in history ever made that observation. Isn't this why we have leap year every four years? The idea of leap year goes back to 45BC.
I like that he included sundials in his "argument". The factthat on all sundials the shadow of the gnomon moves 15 degrees per hour completely disproves his flat earth.
Happy 500th anniversary of the first circumnavigation of the *globe.* By the way, as a former shortwave radio listener, I can confirm that despite getting better reception when pointing your antenna at the transmitter; when listening from the eastern United States it doesn't matter how you aim your antenna when listening to the Australian Broadcasting Company. If the earth were flat, Australia would be in one direction and pointing one's antenna in any other direction would result in poor to no reception. Q.E.D.
Somebody doesn’t understand parallax. And his questions about “why has nobody noticed”- WE NOTICED. Some people assume that anything they don’t know or haven’t noticed, nobody else can or has either. Intellectual narcissism.
Somebody should explain to Eric that we do adjust our calendars to marry up to 24 hour time keeping, we do it be having an extra day in February every 4th year. Amazing Eric can make such leaps while missing leap years.
And one day every 400 years or every century (don't remember well). Because earth revolution around sun and it's rotation are not synchronized. Earth makes one revolution every 365.25xxxx days.
Also some of us literally move the clock by an hour twice a year in order for the daytime to be during the day because of how the position of the earth affects how sunlight hits the earth... Sunrise began at 8:20 on the 29th of October but today began at 7:45 because we switched to winter time (if we went by summer time it would have been 8:45). We rotate the clocks back an hour because the sunrise will start later and later in the day the closer to Christmas we get and have to rotate them forward an hour in the spring again so the sunrise will begin later. It literally takes more than 24 hours for the sun to be in the same position in the sky for us every morning, and less than 24 hours for it to be in the same position during sunset so his definition "a day is 24 hours because that's how long it takes for the sun to be in the same place in the sky" is just so wrong and I do not believe the sun works like that where he lives either!
i love that graphic at about 7 minutes, where it says "this is what our universe is like" and shows all the stars moving in a clockwise direction (wrong), in elliptical shapes near the pole star because of perspective (wrong) and actually moving horizontally near the "horizon" (wrong) and never dipping below the horizon (wrong). i wonder if any flat earthers ever go outside at night and simply look up?
Not to mention that only half the stars that we know exist are on that dome and the edges are moving along at such a rate that I would grow dizzy just staring out my southerly window in Australia.
@@Dave-rd6sp One flat Earther was convinced that the way the stars rotate in the night sky proved the Earth was flat. When I explained that in fact the opposite was true, he was just as adamant that the stars in the night sky don't prove anything about the Earth. 😆
@@Mandelbrot_Set ...and yet, they believe the Moon landings couldn't have happened because astronauts couldn't have survived going through the Van Allen BELTS...
No, he's NOT describing an Earth tidally locked to the Sun. That would make a Sidereal Day equal to a Solar Year. He's confused the Solar or Synodic Day, which is the time it takes the Earth's motion to return the Sun to the same position in the sky as observed from any particular point, with the Sidereal Day, which is the time it take's the Earth's motion to bring the background stars back to the same position in the sky as observed from any particular point. They differ by about 4 minutes, the Sidereal Day being shorter. Non-Solar astronomers care about the Sidereal Day because non-Solar astronomers care which way their instruments are pointed relative to the background stars. Non-Solar astronomers actually DO have clocks that display Sidereal Time, so they can more easily keep track of what's visible in the sky. Dubay is CORRECT that the difference between the length of the Solar and Synodic or Sidereal Days is why observers on the Earth see the Sun's position in the sky gradually move relative to the background stars as the Earth orbits the Sun. He is ALSO correct in stating that the Solar Day changes with the position of the Earth on it's elliptical orbit due to the Earth changing speeds as it passes through different parts of its orbit. The reason this doesn't have any impact on the way we set our clocks (but does affect when the Sun is observed to rise and set, and DOESN'T affect the Sidereal Day) is because we don't set our clocks to the ACTUAL Solar Day, but to the MEAN Solar Day, which is calculated to smooth out the inconsistencies and produce a completely regular day, always the same length, at all times of year.
I came here to type this same thing, but you've worded it better. Dubay is basically completely correct (which is very surprising) except that the earth doesn't rotate around its axis in 24 hours. If it did, all his points would be accurate. Which actually makes this debunking video seem to fail harder than Dubay. That is, upto 6 minutes where it turns out that Dubay _does_ know about this... Wait, how can you know that and then not understand it????
Dan, thank you for all the videos you make. My best friend just passed away and he was a huge science enthusiast and didn't believe me when I told him that there were flat earthers out there. I always got as much enjoyment watching your videos as I did watching my friend watch them. Thank you and keep up the good work!
"nobody sets their clocks by the sidereal day". Good self debunk there. The first diagram, that's showing 12noon as being based on the sidereal rotation is exactly where Eric started lying.

Aww. Eric was so dazzled by his own brilliance, he forgot to show us the map of flat Earth. Or explanation why people living in southern hemisphere see totally different stars at night.

Some concepts from my background (civil engineering, mining/surveying) are not always immediately intuitive, like spherical excess in triangulation networks, or the fact that vertical plumb lines are not parallel, but their arrogance can be more than a little frustrating.
All stars rotate counter-clockwise around Polaris in Flatland. That means that every star would be visible from all locations every night and stars would move horizontally on the horizon. They could never rise or set.
He's got a point. If the earth's rotation was exactly 24 hours and 1 day was exactly 24 hours then the earth could not be orbiting the sun. Fortunately the earth rotates once every 23 hours 56 minutes. Heliocentric model saved.
I'm a big radio nerd... I have been into radios and "on the air" for 30+ years. I wish a Flat Earther would do a video explaining how they believe radio waves, and solar cycles effecting radio waves work on a flat Earth.
This was hilarious. I've never thought about the issue that Erik brought up with his picture. But five seconds of thinking about 'problem' made it clear to me that this actually supports the helio centric model and globe earth.
I love the way Dubay shows a celestial hemisphere labelled as a _sphere_ or Polaris visible from everywhere but uses captions such as 'this is not observed. Hence X does not exist.' You don't say! The lack of self-awareness is astounding.
i like how eric calls out a potential problem with the earth having to speed up and slow down(it's rotation doesn't but its orbital speed does slightly) but has no issues with his model needing the sun to not only speed up and slow down but also move back and forth to hit the tropics.
"Then why hasn't anyone in history ever noticed that our 24 hour clocks... fall behind reality 4 minutes every single day?" We have, Eric. Ever heard of Leap Years?
Ähm. No. Sorry Leap years have nothing to do with that. Leap years account or the fact, that earth doesn't need exactly 365 days for one trip around the sun but slightly longer. In (roughly) 4 years this discrepancy sums up to 1 full day. But you can see the difference very easily by watching the stars in 1 (or more) consecutive nights. Watch a star show up (or vanish behind) some object (eg. a house) and note the time. Do the same the next night with the same star and the same object from the same point of view. You will notice that the event takes place 4 minutes earlier then the night before. So earth did not need 24 hours for 1 full rotation but 4 minutes less.
@@kallewirsch2263 ....Well in that case, how _DO_ clocks account for the time difference? If they repeat every 24 hours then they would drift 4 minutes every day, but if they actually repeat every 23 hours 56 minutes then that means "one minute" is actually 59.933 seconds long. Has one minute really never been one minute? Whatever the case, it's still funny that he didn't even mention leap years and try to explain why they didn't answer his question.
@@Porkey_Minch They don't. They don't need to. Clocks do not count 360° rotations of the earth. Clocks are set in such a way that their counting is based on "noon - noon". That is what we call a day, that is what we call 24 hours and yes, that is more then a full 360° rotation. It isn't complicated. Really it isn't. You just have to let go of the idea, that earth turns 360° in 24 hours. Even if this is popular belief, it doesn't. it turns a little bit more, almost 1° more. However unless you are an astronomer, you don't care. All you are interested is, that if your clock shows 12 at noon, it should show 12 at noon the next day. That earth needed to rotate 361° fot this to happen is completely of no interest to anybody (except astronomers). We just want a mechanism which is synchronized to this noon-noon events and we arbitrarily divide this period in 24 hours and break this hours down into minutes and seconds. The modern definition of a second (which is no longer based o nearth rotation) is designed in such a way to be compatible with that ancient definiton. THat is why the modern definition contains such "fancy" numbers. Leap years on the other hand are intruduced to account for the fact that the path around sun is not evenly divisable by days. It takes earth roughly 365 AND A QUARTER days to complete one revolution about sun. It is this (almost) a quarter, which is accounted for in leap years.
@@kallewirsch2263 Oh right, I get it now. It's hard to understand properly without a visual representation. Still, I'm surprised he didn't address leap years at all. Maybe he will in a different video, who knows. Or maybe he knows it could lead people too close to reality so he doesn't want to stray into the topic.
I love how they perpetually try to say that science is lying, yet offer ZERO proof that explains the universe from a flat earth perspective. The depths of their incredulity amazes me. (a.... 15 degree per hour drift. [thanks Bob])
When he says that he also tells ppl what to test and how to observe. Its like the do you're own reserch line then a flatherfer will post links to this clown shows 200 proofs and other garbage.
Today, I found out that a friend is a Flat Earther. I was kind of shocked because he is a fairly intelligent person. The thing that was annoying me more than anything about this, was that even though I explained to him so many things that show he is wrong, and that not one single claim about a flat earth has EVER withstood actual testing, his sole arguement was that no one will fly over the south pole because you cannot do it. Now, I did say that was astupiod thing to say because in order to do that, you wwill have to fly, possibly from South america over the pole and then continue on, until you get to get to Australia, and that distance is simply too far to cross... But he was not listening... He just said no one will do it. I also said that it costs too much and so no one cares enough to prove it either way because no one gives any respect for Flat earth believers. He was just annoying me by simply repeating that Im wrong and that he is right, but not being able to make any claim other that to go over the south pole??? Has anyone got anything that will get him to STFU about this? Better still, had it been done? I am actually genuinnely annoyed by how much he has got to me I have to be honest.
I can respect how the flat earthers want to do their own research, it shows a level of independence and curiosity. Combined with a massive lack of scientific literacy, however, and they end up with a mountain of faulty conclusions... The least the could do is try to understand the model before they try to debunk it.
This is one of those things where he’s wrong on such a basic, fundamental level that it’s hard to even describe how he’s wrong The clock was created to approximate the day. Not to arbitrarily confine a day to our convenience. Most of the time it’s just close enough to not matter to our day to day lives. I wonder what Eric thinks leap years are. Because if we’re using human approximation as an absolute standard (which he seems to think is the case), it should take exactly 365 days for the sun to orbit around us, no more, no less. So why do we need to insert an extra day? And why does that extra day fix our time, instead of breaking it?
it's so basic and fundamental that i learned about the rotation of the earth in primary school when i was 6, and still understood it better at that age than he understands it now
Every flat earther “proof” boils down to the same scenario over and over: mistaking [their incorrect interpretation that the model is incorrect] for [their proof that the model is incorrect]. Luckily, they are immune to this happening back to them, because they don’t have a model that explains reality, so there is no correct way to interpret how they think things work.
They are the masters at straw man arguments. He is always like the globe believers say this or that when in fact not a single one of them says this or that. He than tries to pretend his inserted claim of globe science understanders that was never used is somehow false, when in reality he just used a logical fallacy to be ingenious to prove is fake pretend point. I hate his voice too he sounds like such a creep.
There was a lot of pictures of stars. Maybe I have a dumb question on the flat earth model. I should be able to see at some point every visible star and constellation. Why can’t I ever see some of the constellations in the Southern Hemisphere or on the outer edge of the flat earth model .?
What I consistently fail to understand is this: Given there was a gigantic coverup including every single pilot, stewardess, ship captain, GPS/Glonass etc. people and everyone else who must rely on the world being the way it is for their jobs and the earth really actually was flat. Why would all of these people consistently lie, why would their companies operate on principles that aren't true, doing stuff that can't be done, and how the heck would those companies still end up making money? Who's paying for all of this, and why? On this world nothing happens unless someone earns money from it, so who's earning here and how? If I were running an airline and I would see my company going under because of the pandemic and the price wars etc. as has been happening in the last two years all over the place, why would I rather go bankrupt than just fly the straight way, save a lot of fuel and thereby keep thousands of people employed?
Ah, but they "do" fly straight, they just log flight plans saying they'll follow a curved path, show in-window footage of the wrong geographical locations, and have a computer accurately simulate all the appropriate data for the flight recorder. See? Money saved.
If there was a screen in every passenger plane window, that would be a) horribly expensive to maintain on the airline's side (what if just one of the screens ever failed during flight?), b) rather suspicious (airlines buying lots and lots of display tech and employing people to deal with it) and c) very easy to expose from the flat earther's side (just "accidentally" damage a window during boarding and show the world that the airlines are lying). Also, cruise ships can't be walled in with displays, and there are whole companies maintaining satellite coverage for navigation. What do they do for a living if satellites don't work? Even more: why doesn't anyone take an older, non-computerized car "tuned" for the North Americas on a ferry over to Australia and closely compare the (mechanical, unaltered) odometer to the navigation app's distances on the phone? It should be off by a large margin because Australia has to be a lot bigger on a plane than it is on a globe. I keep not getting it. The two flat earthers I actually ever talked to were far from stupid, but they sure did employ their intellect in ways I can't wrap my head around.
So basically he doesn’t understand that the day doesn’t represent a literal 360 degree rotation. When people invented clocks, they based it on when the aiming rose from their perspective. Not based on the literal earths rotation
There's also the remaining quarter day each year that we make up for on leap years, yet Dubay can't even acknowledge that as messing with his overly literal perfect cartoon. Unless he also wants to claim that there are no leap years.
As to his "clocks are falling behind every day" point. This is actually addressed in the Gregorian Calendar, what do you think the leap year is for, Mr. Yoga?
No, that is a different thing. What he means is the difference between the sideral time and the apparent solar time (that you can observe with a sundial). The difference is about 4min every day. Which makes absolutely sense, this is the 1/365 of one whole day.
We need a leap year because one revolution around the Sun takes not exactly 365 days, but ~365.24 days. This has nothing to do with day and night in the first place.
Julian calendar also had leap years. Only there were every 4th year. So a year was 365.25 days long. Error accumulated to 1 full day in about 137 years. In Gregorian calendar, a year is 365.2425 days long, which a way more presice. We would be one day off after year 5000. I think if we told Eric, that in Italy, Thursday 4 October 1582 was followed by Friday 15 October 1582, he would loose his mind. Such a conspiracy...
I actually use this question in interviews for engineering interns - (with diagram) every 6 months day and night should flip because we're on the opposite side of the sun, but this isn't the case - why? Of course the answer is the difference between a solar day and a sidereal day, I do tell them I don't expect the answer, but I like to see how they reason, esp when given a difficult question in a high pressure situation
@@davidlawrence5148 It wasn't about getting it right - although one did, they went one for a minute about how that reasoning may not be sound, a few tried to offer reasoning but were ultimately BSing on the spot, the one I hired had the right tact to say "something doesn't quite seem right, if I were to take it away I'd come back with a well reasoned answer" - which for someone to be a field rep is the right approach
@@magusmelanie828 ok I get that, but in the field it's more acceptable to say "ok let me consult my colleague about this" or something whereas in an interview I think it's a less obvious answer, especially for a young person. They could literally think well I have to get this science question right or I've failed the interview. Still you did say you don't expect them to get it right and obviously I have no idea how it fits in the context of the rest of the interview. What would you say if a candidate pointed out that the diagram was intellectually dishonest, because if like Eric's diagram, the times of day stated cannot be true?
I think if I was asked this I would admit I was already familiar with the problem and offer both an obtuse answer and a friendly answer to demonstrate the difference.
@ApocalypseOfSpoons nearly.. day and night are a combined effect of the absolute rotation *and* our orbital position. The reason our clocks don't get out of sync quickly is because this is exactly what we have calibrated our clocks to, the solar day. Eric dishonestly says that 24hrs represents the time earth takes to rotate. This is wrong and our clocks go round once per day night cycle because *that* is how we *define* 24 hours. (Edit: and this is more an example of an obtuse explanation rather than a friendly one as I am doing it on my mobile after a beer)
There is a very subtle speeding up and slowing down. That’s why we call it _mean_ solar time. That’s why an analemma looks the way it does. The heliocentric globe model explains it very nicely indeed.
Wow, him talking about how the stars and the sun not following the exact same rotation was mind-blowing. He really thinks it's more probable that they just happen to rotate at the exact difference needed for the globe model to add up. For a movement that loves jumping to incredulity over things that seem like happenstance that sure is a hell of a coincidence.
The physics of a globe earth make sense. I can not figure out at all how flat earth works, unless they believe the earth was created by god and magic is possible
Classic strawman argument from Eric Dubay there: Create an obviously wrong representation of the heliocentric model, prove that the wrongly made model is wrong (duh!), and then claim the earth can't be a globe. Fools will fall for this strawman, I'm sure.
This is on par with the "back of the sun" claim from flat earth fail 8. Nothing has yet beat that in my mind. I use that video whenever I feel down to pick me right back up again 😂
Massive helpings of word salad. Not a single flat-earther has produced a 3-dimensional model that accurately demonstrates their claim of the nature of Earth and its place in the universe.
Interesting watching experience. Halfway through going like 'someone should really tell him about sidereal time', followed by 'oh he does know about sidereal time... whut?'
We are being quantum teased by God. He sits back and watches humankind play out their sicknesses. He looks upon us and says that we were a noble experiment... that failed. And then another immense detailed crop circle shows up overnight (in the dark) and all the idiots declare that they are "of course" made by some human pranksters over the length of a single night. Yeah, sure, bub. See dem bent over joints in dem plants. M R Ducks. OSAR! See dem wings? Instant quantum karma is gonna get you... I want to start a heavy mettle band!
"Earth's rotation doesn't speed up or slow down", that's true but the sun apparently changes it's speed through the sky and we don't ever notice this? Well done Dan for making it through this, it was so unbelievably stupid I couldn't even follow his stream of nonsense
The sun does alter Earth's rotation, but very slightly. Also, the rotation is gradually slowing down, every day, due to many forces, so every day is getting a little bit longer, by like 15 microseconds or something.
*"The best time to plant a tree was 20 years ago and the next best time is now"* I consider this to be best motivational quote I've heard in a very long time. But motivational quotes are useless if you don't practice what you preach*

There is clear evidence that he is a sociopath and don't actually think he is ignorant, therefore he is a con artist and the movie could be better titled: "Paycheck: Stealing from the delusional Narcissistic"
"Since elephants have tusks, that is clear proof of Mr. Peel" - Eric Dubays way of arguing Just don't ask him to explain the causalities and coherences in his arguments.
Actually, some elephants have evolved rather quickly to not have tusks in recent decennia, because tuskless elephants weren't killed by humans. However, it still proves the existence of Dr. Peel.
Deary me... that is the most agressive case of Duning-Krueger i have ever seen. It represents flat earthers in a nutshell. Lack of knowledge and thinking they know best. Haha it is so funny to hear him call others woefully ignorant. That projection! 🤣
I've seen some astonishing Dunning kruger from some flat earthers. Including one who claimed all mathematics is made up and nonsense. I began to explain how engineering is literally based on maths and everything from cars to buildings, bridges and even the computer he was using to watch RUclips couldn't have been designed without mathematics. He proceeded to tell me that engineering has nothing to do with maths despite admitting to having zero education on the subject. I'm an Engineer with a decade of experience but he still told me everything I said was wrong. He actually believes he knows more about engineering than an actual engineer with 10 years experience whilst he hasn't ever read a single textbook or worked a single day in the field. Now that is pure dunning kruger syndrome.
10:15 um actually Dan, the orbit around the sun does affect the day somehow, I am not guru on this but Equation Of Time is a thing.

Yes, the Earth moves faster when we are closest to the Sun, so it takes a little bit longer to rotate the Sun back to where it was the day before
But not to the extreme degree that ED here is trying to exaggerate.
None of the times based on celestial objects are perfectly aligned - the Moon being the most obvious given Lunar calendars get out of date real quick. The question is how much of a difference any of this makes - clearly the smaller the difference the less apparent this is. The speed of rotation of the Earth is actually slowing down as well as the revolution around the sun. That means days and years are getting longer - so would actually line up at some point after we're all dead.
@@deusEXmachinaV42 In my other comment I looked up the different orbital speeds and they vary by about 10% between the extremes. So +-5% Though keep in mind that's 5% of those additional 4 minutes per day so just about +-12 seconds in total
The definition of the hour is 1/24th of the *mean* solar day. With the fact that sunrise and sunset times are varying seasonally, the average (excuse the pun) person wouldn't be able to tell that individual solar days vary in length.

I told this theory to my cat. She just looked at me, shook her head and went to her experiments on gravity. Knocking another item off my desk. I know she has done that experiment before but science has to be repeatable, and as all cats are world self proclaimed sceintist, they will continue to test their gravitational experiments as long as I keep putting items on my desk she can knock off. This proves cats understand science better than all flat earthers.
Cats are indeed a useful bit of kit when it comes to explaining a globe earth rather than a flat one. If the earth were truly flat it would just be a flat disc with nothing at all on it. After all these millions of years cats would by now have knocked everything off the edge.

@@Connection-Lost I am convinced of that myself. Eric is no more a flat earther than any of us, but he is a con artist and is making bank off idiots.
Honestly I think this is the least confusingly stupid thing flerfs have ever come up with. With this, you can _understand_ why they're misunderstanding reality. Usually it's complete squirrrelshit nuttery all the way through, but he's _partially correct_ with this and doesn't know it. Day and night do "switch places", it just doesn't matter because he misunderstands what a 'day' means and how long a year is, how insignificant the change is from day to day, and that we live in a 3D universe, not a 2D flatbrain flerf fantasy world.
So nothing new, really. I think he just tripped and fell accidentally close to making an actual point. Chalk it up to statistical error. A child could understand why he's wrong with minimal explanation, but a child might wonder the same thing.
If this is progress, and not dumbfuckery accidentally approaching a (1) wit, then in a few decades flerfs might ask an interesting question that doesn't induce lethal facepalming. Maybe. Optimism, ho!

He is immediately wrong in the phrase: "[according to the globe theory] ...Earth makes one complete rotation on its axis every 24 hours." No, no it doesn't. It makes one complete rotation in 23 hours and 56 minutes (sidereal day). It takes an additional four minutes (approximately) for it to rotate to face the sun precisely, due the movement in orbit between one day and the next. (The four minutes is approximate due to the eccentricity of earth's orbit and the vector addition of its tilted rotation with the orbital motion.) Since we keep time according to mean solar days, not sidereal days, the sun is never going to be on the other side of the globe at local noon.
The difference between mean solar time and local sun time (sundial indication) has been known since accurate clocks were first made, and is called the "equation of time." So, he's wrong again when he says solar days are exactly 24 hours long. No, their length varies throughout the year due to the varying orbital speed and relative tilt.
Precisely this.
Well said oldtvnut, I had made some explanation similar to yours, but this one is even better. 👏👍
Uau... Thank you.
Well written!
I've seen Eric Dubay run this "argument" several times before. He basically swaps the definitions of sidereal and solar days, then claim it leads to contradictions. That is indeed true, misrepresenting definitions does lead to inconsistencies.
Also, his statement looks like he took something, let it be wooden bar with length of 1 meter, measures it and says - "hey, its length is 1 meter, what a coinkidink!".
But it is MADE SO. People MADE timescale to fit it to day and night, to make it useful. Gosh.
I love how he says: this doesn't work, and then exactly explains how it DOES work and then says: so you see it is bullshit.
SciManDan, I can't believe you had had to say out loud, “the daytime is always going to be the part of the earth facing the sun.”
I laughed out loud hearing you say that out loud. 😂🤣😆

"Do you see a problem here" Yes Eric we do see a problem here.
Lol 😂
I love the fact that one of his arguments against a globe is that Earth must speed up and down, when we globe-earthers have been pointing out over and over again that the sun must do the same if the flat earth model shall have any chance of explaining the seasons.
Yes, the Sun needing to "change lanes" between the Tropics of Cancer and Capricorn, which on the Flat Earth diagram (no model, so they say) would require speed changes to maintain the same time per rotation around the North Pole axis.
The issue is that the radius and the speed change are opposite in those two scenarios. On FE, the larger radius must go faster to keep the day at 24 hours. With earth's orbit, as the radius reduces as we get to the perihelion, and consequently speed up. One of these makes sense in physics.
@@Ravaxr I wonder what they think would be the reason of the sun speeding up.. I would guess "Because mah God". It's always the argument that can't be disproven as God just is un-falsifiable... :/
We live on a fixed, flat earth; it’s just stretched all the way around a spinning, spherical ball that orbits a star...
It's amazing to see someone gather all the pieces of information he needs, then completely fail to assemble them into anything resembling logic.
I know, I couldn't believe what I was hearing. He was like "It's a problem for the globe model because the sun would get 180 degrees out of sync with clock time" but then actually accepts that there's a difference between the solar day and 360 degree rotation day and COMPLETELY FUCKING FAILS to put two and two together to see he has exactly what he was looking for to solve his stupid "paradox".
I can't understand how you fail that badly. It's not like other flat earth nonsense that's just denying reality. He explicitly accepts the key fact, and completely drops the ball on understanding it.

It's bizarre that he knows time is based on the solar day, not sidereal one, forcing noon to be when the Sun is highest, yet can't understand time was invented to be independent of the sidereal day.
My guess is that he well understands it. Its just his usual blablah in order to fool the fools. I don´t really know what for, but it has something to do with fame in his own little bubble.
He somehow thinks the sidereal day is the one the clocks keep track of. That's kind of amazing because he's kind of right, if our clocks were set so a day is 23 hours and 56 minutes the day would drift out of track of the day/night cycle, the problem of course is no one other than astrologists care about the sidereal time.
The difference between sidereal and actual time could easily be overcome with a sundial. We would all just be on slightly different times globally. This is what makes his theory so preposterous.
They think that bc of the 4mins delay, there would be an inconsistent in sunrise and sunset (which does varied due to different reason so we can't see it without taking those reason into account (and no fking normal people take those reason into account when announce the sunrise and sunset time)) But I think that those delay doesn't happen 365 days a year, so 4 * 365 mins of delay calculation doesn't work. For very accurate measure of time, they did include these 4 mins and the prediction and stuff just match the reality to an extreme degree.
Interestingly enough, if you place someone underground with no sunlight and no clocks, their sleep cycle rapidly approaches the period of time it takes the moon to return to the same position _above the earth._ I hesitate to call this a lunar day to avoid confusing it with the period it takes the moon to rotate on its axis. One has to assume that this phenomenon is linked to the tidal forces generated by the moon.
I care (celestial navigation interest).
Yes! I was going to make the same comment! The sidereal day ( the time for the globe to rotate around its axis relative to the stars) is only ~ 23 hours and 56 minutes but as the globe also moves around the sun it needs an extra 4 min to rotate around its axis relative to the sun. So that makes up for a complete year. Number of days in a year is 365 ==> 365 * 4 min = 1460 min = 24 hours . This very easy to verify for yourself which I did about 2 years ago. Take some pictures of the night sky and the stars from the same position and observe the positions of some bright stars relative to some building or trees some 100 meters away. If you take the pictures 1 week apart, you will notice a 28 minutes difference in time ( 7 * 4 min) for the stars to be in the same position. Easy!!
It's amazing how someone who described a sidereal and solar day so perfectly doesn't understand how they work in a 3D model.
It doesn't even need a 3d model. You can see it in a 2d model of the rotations. The "day and night would flip" he is referring to, DOES HAPPEN. That roughly 4 min difference between the two "days" adds up to 12 hrs over the course of half a year. If you just draw 2d circles on a paper ad make a tic mark on the earth to show it's 360deg rotation point as "noon", yes, by the time it goes through half a year that sidereal day returns to it's position on the page at midnight on the other side of the sun. He is right about that. But it's because of that 4 min difference - do the math- 12 hrs in half a year. That's why we see different stars in the winter than we do in the summer. The sun and stars don't move (relative to a year), the earth rotation and the "problem" he is highlighting explain why we see what we do. It comports with observable reality.
@@militaryartandscience yeah this is exactly it. The problem is he thinks we use the sidereal day to tell time and we don't lol. We use the solar day.
@@militaryartandscience But why is it that it's exactly 12 hours over half a year and 24 hours over a year? COINCIDENCE?? I THINK NOT!!11! /s
For real, the problem is exactly that, I think this is a perfect example for this kind of fallacy: most seem to come from a biblical viewpoint, where things like days are defined by god, and then you'd apply those terms to scientific models and find coincidences all over. And I get it, if you think of 1 day as 24 hours and then looking at the globes "supposed" movements, his explanation seems logical. Until you realize, the earth was here long before humans existed, an hour is just an arbitrary measurement, 1/24 of a day, and a day was defined by humans in ancient times as "sun down, sun up again". And that day therefore INCLUDES the rotation around the sun and all the stuff that's been already going on for millions of years (I know, leap seconds, leap year...).
He doesn't realize that the clock was created to reflect the day and not the other way around. I see the hoops his mind jumped through to come to this conclusion, but that tiny bit of extra rotation that happens every day is already built in to our calculations of time. He thinks that the calculated rotation of the planet should be based on some universal coordinate system, and not on our own star. As anyone could quickly figure out, if they gave it some real thought, this is not only an improbable request, but highly impractical, and irrelevant effort for our daily purposes.
No, everyone knows that there's a great big grandfather clock in heaven that the Bible forgot to mention being created just before the earth was created at exactly 6 p.m. on Sunday, October 23, 4004 BC (Julian Calendar), and the length of the day was set to match two revolutions of this clock's hour hand. Didn't any of you people go to Sunday School?
I think that this is the crucial fact that Dan didn’t really explain to well. The solar day is the time it takes the globe to spin relative to the sun and we, ie humans, defined that as 24 hours long before the sidereal day was fully understood. But it is the difference between solar and sidereal that account for the ‘flip’ the earth makes in 6 months.

I have to try to block out logic and known facts to get a mental picture how their theory would work. Then I'm even more perplexed that they believe this theory despite it being so obviously wrong and a total contradiction of observed reality.

Actually flarf here is correct. If 24 hours equalled a 360-degree rotation, sunrise would slowly walk around the planet each year. However, 24hours doesn't equal 360 degrees; it's slightly more to compensate for the earth's rotation. (It's also not 24 hours exact, but you know).
So yes, every 6 months, day and night flip. It just does so a little at less than 1 degree per day

does he honestly think the fact that the day happens to be 24 hours is a coincidence? Like the clocks were made first and they just happened to match how long a day is? The day is what it is and we divided it into 24 hour long units for our convenience.
Probably. I mean they are all about "observing with your own eyes". Since they probably see a clock first and then that the earth is flat its probably how they put that together. They call it a "model" We call it "making it up as they go along"
Exactly. If the earth rotated exactly 2% slower than it does, every day, every hour, every minute, and every second would be exactly 2% shorter than they are. Those are all completely arbitrary units indexed to the length of one solar day.
(Yes, I realize that the SI second is now indexed to regular fluctuations of the caesium-133 atom, but the constant that links these two things is also completely arbitrary and was set to make one second equal to one 86,400th of one solar day.)

Shouldn’t that be six MONTHS of each?
6:01 I'm confused at Dan's rejection of Dubay on this point. Dubay says we use the ~4 minute shorter sidereal days to explain why day/night doesn't flip. Then Dan says "Nope. No one's saying that".
But... isn't that exactly the right defense to use against Dubay's claim?
Say you have a normal clock, and a sidereal clock. The "sidereal" clock runs 4 minutes fast. After 6 months, it will be exactly 12 hours ahead of the normal clock (4 min * 6 months = 12 hours).
Dubay is pointing at a sidereal clock and saying "See! After 6 months, it's nighttime at noon and daytime at midnight!". So the appropriate counter is "But that's because the clock you're using runs 4 minutes fast every single day for 6 months"?
I really appreciate that Eric uses images of star trails in this 'presentation'. Perhaps he could look at two side by side, one taken from anywhere in the northern hemisphere and the other taken from the southern hemisphere. If he did and was paying attention he would note that in one of them the trail moves clockwise and in the other it moves anticlockwise. Maybe he could then go on to explain how, on a flat earth, people in Europe or North America see the stars moving in one direction whilst simultaneously people in Australia or South America see the stars moving in the opposite direction. Perhaps he could build a model to demonstrate this amazing phenomenon ......... or there again, maybe he couldn't.
And how people in South America and Australia, can look in opposite directions and see the same stars at the same time to the south.
Very difficult on a flat earth.
@@grahvis Not difficult on a flat earth.
Absolutely impossible 😆🤣
@@grahvis Or how it can be that everybody north of the equator can see the star Polaris but nobody south of the equator can. What is so frustrating is that all of these flat earthers know these things, they know full well that they are impossible on a flat earth yet they simply ignore it and still persist in peddling this rubbish.
Yes, the existence of two celestial poles of rotation, South and North, is impossible in the usual flat Earth model, but has been well known for a long time and is documented in many photographs,
While he's at it, can't he make a modell where the stars rotate in a circle instead of in an elliptical pattern on a flat earth model on any other place than the north pole. I won't hold my breath...
"The earth makes a full rotation every 24 hours ..." is wrong. The length of a full rotation is a bit more than 23 hours 56 minutes (sidereal day). Every 24 hours it will face the sun at around 12 o'clock (solar day). No night and day flipping required.
Exactly - and that's what they mixed up and that's where this misunderstanding comes. Imho this is the best observation I've ever seen from a flat earther.
The thing is: they should've look into it a bit deeper, instead of thinking everybody missed this hole in the globe Earth model...
It's also important to point out that the solar day is ON AVERAGE 24hrs, but it does change through the year due to the elliptical orbit. This is part of what causes the analemma
@@isuller I thought so too for the first half of the video, but then ED out-did himself by showing that he actually knows about solar and sidereal days, but "it's a lie".
Yes basically the earth makes a little bit more than a full rotation to account for the orbit around the sun.
Thanks for pointing this out, Dan spent the whole video arguing against a strawman. Probably the smartest question a FE has asked though tbh
Eric's argument works, because he gets one thing fundamentally wrong. The Earth doesn't spin on its axis in 24 hours, but in 23 hours, 56 minutes and 41 seconds. It takes 3 minutes and 19 seconds more to face the sun because while it's rotating on itself, it's also revolving around the sun.
He's using solar days as sidereal days.
The bizarre thing is that he brings up sidereal days, but then dismisses them as somehow not being relevant.
@@Beacon80 our clocks would fall behind 6 hours in six months if the earth spin at 23 hours 56 minutes you Dumbo

@@Beacon80 that is my point, our sun would set four minutes later everyday because earth is spinning faster than hours
@@yahschild9348 I don't think you understand the difference between a sidereal day and a solar day.
Let's start a high noon. 23 hours and 56 minutes later, the earth has made a full rotation (a sidereal day). However, the sun is 4 minutes away from the next high noon, because in that time the earth has moved along its orbit. The earth needs to rotate roughly 361 degrees which takes another 4 minutes. This gives us a solar day of 24 hours. Since the solar day is built around the sun returning to the same point, our clocks remain accurate.
If flerfers actually understood the globe models, they probably wouldn't be flerfers.

He clearly understands the difference between the sidereal day and the solar day. He knows that the stars seem to move faster than the sun. His explanation proves of the heliocentric model, so it's funny how he comes to a different conclusion. In fact I would say it's one of the best proofs for heliocentrism and round earth.
He's overthinking things, and he forgot the clear thing that a day is 24h because that's just how we decided it is, not because we created the model and based all our timekeeping on it.
That seems to be the way a lot of the "proofs" go. They look at something that clearly indicates our actual globe, spinning while orbiting the sun, and say "See!!! FLAT EARTH!!!" :D
He understands those two differences, but comes to a different conclusion to literally everyone else because he is utterly convinced for absolutely no reason that the Earth is a fixed point in spacetime and the entire universe revolves around his tiny little brain... It's hilarious really...
And the funny thing is that he didn't do his calculation of day / night flipping with the sidereal day. As the sidereal day is 4 min shorter than solar day, you accumulate about 12 hours difference over 6 months. So day and night do shift places if you count days on the sidereal calendar.
I think he does understand and is being deliberately misleading to his viewers
Yes, finally
The only video that reminds me that today is Friday.
Eric says we "suddenly claim the earth rotates 23 hours 56 minutes" and that nobody in history ever made that observation. Isn't this why we have leap year every four years? The idea of leap year goes back to 45BC.

Happy 500th anniversary of the first circumnavigation of the *globe.* By the way, as a former shortwave radio listener, I can confirm that despite getting better reception when pointing your antenna at the transmitter; when listening from the eastern United States it doesn't matter how you aim your antenna when listening to the Australian Broadcasting Company. If the earth were flat, Australia would be in one direction and pointing one's antenna in any other direction would result in poor to no reception. Q.E.D.

Somebody should explain to Eric that we do adjust our calendars to marry up to 24 hour time keeping, we do it be having an extra day in February every 4th year. Amazing Eric can make such leaps while missing leap years.
And one day every 400 years or every century (don't remember well).
Because earth revolution around sun and it's rotation are not synchronized.
Earth makes one revolution every 365.25xxxx days.
Leap days are because the year is about 365.25 days long, hence one extra day every four years (usually).
Also some of us literally move the clock by an hour twice a year in order for the daytime to be during the day because of how the position of the earth affects how sunlight hits the earth... Sunrise began at 8:20 on the 29th of October but today began at 7:45 because we switched to winter time (if we went by summer time it would have been 8:45). We rotate the clocks back an hour because the sunrise will start later and later in the day the closer to Christmas we get and have to rotate them forward an hour in the spring again so the sunrise will begin later. It literally takes more than 24 hours for the sun to be in the same position in the sky for us every morning, and less than 24 hours for it to be in the same position during sunset so his definition "a day is 24 hours because that's how long it takes for the sun to be in the same place in the sky" is just so wrong and I do not believe the sun works like that where he lives either!

No, he's NOT describing an Earth tidally locked to the Sun. That would make a Sidereal Day equal to a Solar Year. He's confused the Solar or Synodic Day, which is the time it takes the Earth's motion to return the Sun to the same position in the sky as observed from any particular point, with the Sidereal Day, which is the time it take's the Earth's motion to bring the background stars back to the same position in the sky as observed from any particular point. They differ by about 4 minutes, the Sidereal Day being shorter. Non-Solar astronomers care about the Sidereal Day because non-Solar astronomers care which way their instruments are pointed relative to the background stars. Non-Solar astronomers actually DO have clocks that display Sidereal Time, so they can more easily keep track of what's visible in the sky.
Dubay is CORRECT that the difference between the length of the Solar and Synodic or Sidereal Days is why observers on the Earth see the Sun's position in the sky gradually move relative to the background stars as the Earth orbits the Sun. He is ALSO correct in stating that the Solar Day changes with the position of the Earth on it's elliptical orbit due to the Earth changing speeds as it passes through different parts of its orbit. The reason this doesn't have any impact on the way we set our clocks (but does affect when the Sun is observed to rise and set, and DOESN'T affect the Sidereal Day) is because we don't set our clocks to the ACTUAL Solar Day, but to the MEAN Solar Day, which is calculated to smooth out the inconsistencies and produce a completely regular day, always the same length, at all times of year.
I came here to type this same thing, but you've worded it better. Dubay is basically completely correct (which is very surprising) except that the earth doesn't rotate around its axis in 24 hours. If it did, all his points would be accurate. Which actually makes this debunking video seem to fail harder than Dubay. That is, upto 6 minutes where it turns out that Dubay _does_ know about this... Wait, how can you know that and then not understand it????

All stars rotate counter-clockwise around Polaris in Flatland. That means that every star would be visible from all locations every night and stars would move horizontally on the horizon. They could never rise or set.
He's got a point. If the earth's rotation was exactly 24 hours and 1 day was exactly 24 hours then the earth could not be orbiting the sun. Fortunately the earth rotates once every 23 hours 56 minutes. Heliocentric model saved.

i like how eric calls out a potential problem with the earth having to speed up and slow down(it's rotation doesn't but its orbital speed does slightly) but has no issues with his model needing the sun to not only speed up and slow down but also move back and forth to hit the tropics.
24 hours is not for 360 degrees rotation. 24 hours is for 361 degrees rotation. From noon to noon next day.
"Then why hasn't anyone in history ever noticed that our 24 hour clocks... fall behind reality 4 minutes every single day?"
We have, Eric. Ever heard of Leap Years?

Leap years have nothing to do with that.
Leap years account or the fact, that earth doesn't need exactly 365 days for one trip around the sun but slightly longer. In (roughly) 4 years this discrepancy sums up to 1 full day.
But you can see the difference very easily by watching the stars in 1 (or more) consecutive nights. Watch a star show up (or vanish behind) some object (eg. a house) and note the time. Do the same the next night with the same star and the same object from the same point of view. You will notice that the event takes place 4 minutes earlier then the night before. So earth did not need 24 hours for 1 full rotation but 4 minutes less.
ask about 1582, why 4th oct was followed by 15th oct.
@@kallewirsch2263 ....Well in that case, how _DO_ clocks account for the time difference? If they repeat every 24 hours then they would drift 4 minutes every day, but if they actually repeat every 23 hours 56 minutes then that means "one minute" is actually 59.933 seconds long. Has one minute really never been one minute?
Whatever the case, it's still funny that he didn't even mention leap years and try to explain why they didn't answer his question.
@@Porkey_Minch
They don't. They don't need to. Clocks do not count 360° rotations of the earth. Clocks are set in such a way that their counting is based on "noon - noon". That is what we call a day, that is what we call 24 hours and yes, that is more then a full 360° rotation.
It isn't complicated. Really it isn't. You just have to let go of the idea, that earth turns 360° in 24 hours. Even if this is popular belief, it doesn't. it turns a little bit more, almost 1° more. However unless you are an astronomer, you don't care. All you are interested is, that if your clock shows 12 at noon, it should show 12 at noon the next day. That earth needed to rotate 361° fot this to happen is completely of no interest to anybody (except astronomers). We just want a mechanism which is synchronized to this noon-noon events and we arbitrarily divide this period in 24 hours and break this hours down into minutes and seconds. The modern definition of a second (which is no longer based o nearth rotation) is designed in such a way to be compatible with that ancient definiton. THat is why the modern definition contains such "fancy" numbers.
Leap years on the other hand are intruduced to account for the fact that the path around sun is not evenly divisable by days. It takes earth roughly 365 AND A QUARTER days to complete one revolution about sun. It is this (almost) a quarter, which is accounted for in leap years.
@@kallewirsch2263 Oh right, I get it now. It's hard to understand properly without a visual representation.
Still, I'm surprised he didn't address leap years at all. Maybe he will in a different video, who knows. Or maybe he knows it could lead people too close to reality so he doesn't want to stray into the topic.
I love how they perpetually try to say that science is lying, yet offer ZERO proof that explains the universe from a flat earth perspective. The depths of their incredulity amazes me. (a.... 15 degree per hour drift. [thanks Bob])
You're pathetic! You believe in a spinning ball of water with magical gravity holding and bending trillions of gallons of water aka the globe!
Yes sun does move 15 degrees per hour which equals 1,035 miles! Thanks for proving the sun is in motion.
@@ZackWolfMusic Nice how you provided zero evidence. Was that just to prove the OP right?
@@sigmaoctantis1892 Nice how your butty hurt over my comments.
'test and observe for yourself" is hilarious coming from eric when you can prove hes never done an iota of testing or observing
When he says that he also tells ppl what to test and how to observe. Its like the do you're own reserch line then a flatherfer will post links to this clown shows 200 proofs and other garbage.
Today, I found out that a friend is a Flat Earther.
I was kind of shocked because he is a fairly intelligent person.
The thing that was annoying me more than anything about this, was that even though I explained to him so many things that show he is wrong, and that not one single claim about a flat earth has EVER withstood actual testing, his sole arguement was that no one will fly over the south pole because you cannot do it.
Now, I did say that was astupiod thing to say because in order to do that, you wwill have to fly, possibly from South america over the pole and then continue on, until you get to get to Australia, and that distance is simply too far to cross... But he was not listening... He just said no one will do it. I also said that it costs too much and so no one cares enough to prove it either way because no one gives any respect for Flat earth believers.
He was just annoying me by simply repeating that Im wrong and that he is right, but not being able to make any claim other that to go over the south pole???
Has anyone got anything that will get him to STFU about this?
Better still, had it been done?
I am actually genuinnely annoyed by how much he has got to me I have to be honest.
I can respect how the flat earthers want to do their own research, it shows a level of independence and curiosity. Combined with a massive lack of scientific literacy, however, and they end up with a mountain of faulty conclusions... The least the could do is try to understand the model before they try to debunk it.
This is one of those things where he’s wrong on such a basic, fundamental level that it’s hard to even describe how he’s wrong
The clock was created to approximate the day. Not to arbitrarily confine a day to our convenience. Most of the time it’s just close enough to not matter to our day to day lives.
I wonder what Eric thinks leap years are. Because if we’re using human approximation as an absolute standard (which he seems to think is the case), it should take exactly 365 days for the sun to orbit around us, no more, no less. So why do we need to insert an extra day? And why does that extra day fix our time, instead of breaking it?
it's so basic and fundamental that i learned about the rotation of the earth in primary school when i was 6, and still understood it better at that age than he understands it now
Very strange that in his opening statement he said the earth spins on its own axis but then proceeds to erase it from his mind while stating his case
New globe argument unlocked!
Every flat earther “proof” boils down to the same scenario over and over: mistaking [their incorrect interpretation that the model is incorrect] for [their proof that the model is incorrect]. Luckily, they are immune to this happening back to them, because they don’t have a model that explains reality, so there is no correct way to interpret how they think things work.
They are the masters at straw man arguments. He is always like the globe believers say this or that when in fact not a single one of them says this or that. He than tries to pretend his inserted claim of globe science understanders that was never used is somehow false, when in reality he just used a logical fallacy to be ingenious to prove is fake pretend point. I hate his voice too he sounds like such a creep.
There was a lot of pictures of stars. Maybe I have a dumb question on the flat earth model. I should be able to see at some point every visible star and constellation. Why can’t I ever see some of the constellations in the Southern Hemisphere or on the outer edge of the flat earth model .?
"every single person on earth has a seperate fake sky with separate fake stars following them around."
NOT kidding, eric dubay HIMSELF once said that!
What I consistently fail to understand is this: Given there was a gigantic coverup including every single pilot, stewardess, ship captain, GPS/Glonass etc. people and everyone else who must rely on the world being the way it is for their jobs and the earth really actually was flat. Why would all of these people consistently lie, why would their companies operate on principles that aren't true, doing stuff that can't be done, and how the heck would those companies still end up making money? Who's paying for all of this, and why? On this world nothing happens unless someone earns money from it, so who's earning here and how?
If I were running an airline and I would see my company going under because of the pandemic and the price wars etc. as has been happening in the last two years all over the place, why would I rather go bankrupt than just fly the straight way, save a lot of fuel and thereby keep thousands of people employed?
Ah, but they "do" fly straight, they just log flight plans saying they'll follow a curved path, show in-window footage of the wrong geographical locations, and have a computer accurately simulate all the appropriate data for the flight recorder. See? Money saved.
If there was a screen in every passenger plane window, that would be a) horribly expensive to maintain on the airline's side (what if just one of the screens ever failed during flight?), b) rather suspicious (airlines buying lots and lots of display tech and employing people to deal with it) and c) very easy to expose from the flat earther's side (just "accidentally" damage a window during boarding and show the world that the airlines are lying).
Also, cruise ships can't be walled in with displays, and there are whole companies maintaining satellite coverage for navigation. What do they do for a living if satellites don't work? Even more: why doesn't anyone take an older, non-computerized car "tuned" for the North Americas on a ferry over to Australia and closely compare the (mechanical, unaltered) odometer to the navigation app's distances on the phone? It should be off by a large margin because Australia has to be a lot bigger on a plane than it is on a globe.
I keep not getting it. The two flat earthers I actually ever talked to were far from stupid, but they sure did employ their intellect in ways I can't wrap my head around.

Funniest yet? The gate guy is a hard bar to pass, and there's still Bob.
"A 15 degree per hour drift."
Thanks Bob.
Thanks...
So basically he doesn’t understand that the day doesn’t represent a literal 360 degree rotation. When people invented clocks, they based it on when the aiming rose from their perspective. Not based on the literal earths rotation
Oh shoot, I forgot its friday, thanks for reminding me with your video Dan :)
There's also the remaining quarter day each year that we make up for on leap years, yet Dubay can't even acknowledge that as messing with his overly literal perfect cartoon. Unless he also wants to claim that there are no leap years.
As to his "clocks are falling behind every day" point. This is actually addressed in the Gregorian Calendar, what do you think the leap year is for, Mr. Yoga?
No, that is a different thing. What he means is the difference between the sideral time and the apparent solar time (that you can observe with a sundial). The difference is about 4min every day. Which makes absolutely sense, this is the 1/365 of one whole day.
We need a leap year because one revolution around the Sun takes not exactly 365 days, but ~365.24 days. This has nothing to do with day and night in the first place.
Julian calendar also had leap years. Only there were every 4th year. So a year was 365.25 days long. Error accumulated to 1 full day in about 137 years. In Gregorian calendar, a year is 365.2425 days long, which a way more presice. We would be one day off after year 5000.
I think if we told Eric, that in Italy, Thursday 4 October 1582 was followed by Friday 15 October 1582, he would loose his mind. Such a conspiracy...
@@BHFJohnny I suppose telling him that the October Revolution happened on 7 November, 1917 would just completely blow his mind.
Oh Eric! After all that and it turns out it it's just to plug your Film. Money, money, money! Keep up the good work Scimandan.
I actually use this question in interviews for engineering interns - (with diagram) every 6 months day and night should flip because we're on the opposite side of the sun, but this isn't the case - why? Of course the answer is the difference between a solar day and a sidereal day, I do tell them I don't expect the answer, but I like to see how they reason, esp when given a difficult question in a high pressure situation
That's awesome. How many get it right?
@@davidlawrence5148 It wasn't about getting it right - although one did, they went one for a minute about how that reasoning may not be sound, a few tried to offer reasoning but were ultimately BSing on the spot, the one I hired had the right tact to say "something doesn't quite seem right, if I were to take it away I'd come back with a well reasoned answer" - which for someone to be a field rep is the right approach
@@magusmelanie828 ok I get that, but in the field it's more acceptable to say "ok let me consult my colleague about this" or something whereas in an interview I think it's a less obvious answer, especially for a young person. They could literally think well I have to get this science question right or I've failed the interview. Still you did say you don't expect them to get it right and obviously I have no idea how it fits in the context of the rest of the interview. What would you say if a candidate pointed out that the diagram was intellectually dishonest, because if like Eric's diagram, the times of day stated cannot be true?
I think if I was asked this I would admit I was already familiar with the problem and offer both an obtuse answer and a friendly answer to demonstrate the difference.
@ApocalypseOfSpoons nearly.. day and night are a combined effect of the absolute rotation *and* our orbital position. The reason our clocks don't get out of sync quickly is because this is exactly what we have calibrated our clocks to, the solar day. Eric dishonestly says that 24hrs represents the time earth takes to rotate. This is wrong and our clocks go round once per day night cycle because *that* is how we *define* 24 hours.
(Edit: and this is more an example of an obtuse explanation rather than a friendly one as I am doing it on my mobile after a beer)
There is a very subtle speeding up and slowing down. That’s why we call it _mean_ solar time. That’s why an analemma looks the way it does. The heliocentric globe model explains it very nicely indeed.
"That’s why we call it _mean_ solar time."
- I thought it was because it makes flerfs cry :D
(edit: fixed italic code)
Wow, him talking about how the stars and the sun not following the exact same rotation was mind-blowing. He really thinks it's more probable that they just happen to rotate at the exact difference needed for the globe model to add up. For a movement that loves jumping to incredulity over things that seem like happenstance that sure is a hell of a coincidence.
The physics of a globe earth make sense. I can not figure out at all how flat earth works, unless they believe the earth was created by god and magic is possible
Every time I watch one of Dan's videos, the "flat earth challenge attempts" sign perpetually stuck at "0" always gives me a chuckle. 🤣
Classic strawman argument from Eric Dubay there: Create an obviously wrong representation of the heliocentric model, prove that the wrongly made model is wrong (duh!), and then claim the earth can't be a globe.
Fools will fall for this strawman, I'm sure.
Fools will do what fools do!
This is on par with the "back of the sun" claim from flat earth fail 8.

@@bobbyrayofthefamilysmith24 yeah. Just check the flat earth fails 8 video.
Massive helpings of word salad. Not a single flat-earther has produced a 3-dimensional model that accurately demonstrates their claim of the nature of Earth and its place in the universe.
Yeah. NO model, no NOTHING. ---- My globe model works perfectly, meaning matches observation.
I had this same argument recently. My answer was the day isn’t exactly 24hrs and that’s why we have leap years to make up for that difference in time.
How the hell can he think he's right?
What a fanny.
Interesting watching experience. Halfway through going like 'someone should really tell him about sidereal time', followed by 'oh he does know about sidereal time... whut?'

You never realize how tenuous a grasp some people have on science and physics until you listen to a flat-earther try to persuade you.

"He is yet to produce anything in terms of Flat Earth proof"
I'll be honest, I would be very surprised if he did!
"Earth's rotation doesn't speed up or slow down", that's true but the sun apparently changes it's speed through the sky and we don't ever notice this? Well done Dan for making it through this, it was so unbelievably stupid I couldn't even follow his stream of nonsense
The sun does alter Earth's rotation, but very slightly.
Also, the rotation is gradually slowing down, every day, due to many forces, so every day is getting a little bit longer, by like 15 microseconds or something.
Actually the Earth does slow down. The Earth pulls on the earth with gravity. I believe the ratio is 1 second per 100 years

Eric would be right if we used sidereal days to say what time it is. But we don't. That's why he is wrong (again)...

I've seen some astonishing Dunning kruger from some flat earthers. Including one who claimed all mathematics is made up and nonsense.
I began to explain how engineering is literally based on maths and everything from cars to buildings, bridges and even the computer he was using to watch RUclips couldn't have been designed without mathematics. He proceeded to tell me that engineering has nothing to do with maths despite admitting to having zero education on the subject.
I'm an Engineer with a decade of experience but he still told me everything I said was wrong. He actually believes he knows more about engineering than an actual engineer with 10 years experience whilst he hasn't ever read a single textbook or worked a single day in the field. Now that is pure dunning kruger syndrome.
