I still find it absolutely shocking that this needs to be explained to grown adults. 😂
Scary as $hit is what I call it.
And in the 21st century.
It's hilariously scary 😨
Over and over and over and over and over, and it never sinks in. They just keep spouting the same BS about spinning at 1000 mph. It's pretty much hopeless.
Are we all adaults?
I know there are flerfs.
The earth's rotation really *makes my day* :) .
I see what you did there!
@@Danielaco23
Oops!
I was hoping that I would get away with it.
Oh well. I can't win 'em all ;) .
Ha ha, my kind of joke!
Funny
and flat earth theory is really spreading around the globe.
To quote Professor Dave, "A merry-go-round that only makes one revolution every 24 hours would not be a very exciting ride"
No wonder I'm so bored all the time.
Yet its speed at the equator is about 1400 ft/second. And about 28 ft/second are holding us to the ground... Either scientific dark magic is occurring to make up for what Gravity is not doing. Or them Flat Earther's have realized there is a math problem.
...or its all a simulation, and science is just the physics coding that the if then else conditions determined it does or does not apply to you.
Dave is not a real Professor and the merry go round isn't traveling at 1038mph is it.
@jjevans1693 if you're trying to apply the speed of the earth to a merry-go-round without factoring in proportion please rethink your life choices.
I mean he LITERALLY explained it in the video
@@andrevaz1289 No that's what your doing. If the merry- go- round was the size of the earth how fast would it be spinning. 1038mph. to make one revolution per day.
Imagine having to explain inertia to self proclaimed "scientists"
"If Earth moves so fast, then why don´t we feel it?"-"Did you ever drive a car. Or a bike?"
"If gravity is so strong, then why aren´t we getting squashed in to the ground?"-"Did you ever trip over and fall? Or drop an egg?"
Edit: I´m not sure if I misunderstand the comments, or if I am the one being misunderstood. I just wanted to make fun of flatearthers, just like the video. English isn´t my native tongue, so sorry if I wrote something stupid xD
Favourite part regarding being squished into the ground is, you can always feel it, when you feel the ground under your feet, that feeling of the ground pushing back up against you being you're being pulled into it. Also why people who spend extended time in space need to readjust to living with a sense of weight again, and why someone who is born and raised in space would have a different physiology to us and find it very difficult to exist on the planet, turns out, shockingly, our body's structural dynamics evolved in an environment where there's gravity always acting on us.
I don't ever get gravity deniers who say it isn't real, then use an exact phenomema as gravity to explain why they're pulled to a flat Earth and how going off the edge would make them fall, or try to say those on the sides of the globe would fall off.
So you're saying gravity is real and acknowledging up and down frames of reference based on it, amd therefore gravity cannot be real nor can we base up and down references on a gravity source... as clear a contradiction as any did see.

Ex Flat Earther here. Well done man. You've got the youtube algorithm Gods shining down on you. There must be a need for another channel to blow up. And it looks like its you 👍
Love your channel
Why were you a flat earther, and what made anything convince you since in 99.99% of the cases flat earthers can stare something in the face and claim it's not there.
Like pardovot I'd be very interested to hear about your journey from FE'er back to normality. Can you please share?
@@ShizukuSeiji He has a video on his youtube channel :)
Much appreciated :)
I need to share a conversation I just had below another of Dave's flat Earth videos.
Some guy was saying that you can see far too much of the Chicago skyline from across Lake Michigan for the Earth's surface to be curved.
I told him that was due to refraction caused by differing amounts of water vapour in the air and we know it differs because more or lesser amounts of the upper parts of the hi-rise skyline were visible on different days or at different times on the same day.
I then asked him, if he can sometimes see the upper parts of the buildings, why can he never see the waterfront? Shouldn't he be able to on a flat Earth?
His reply - and I shit you not - was that the waves block the view. He wrote: "the waves in front of ur vision block the bottoms. a 12 inch wave at 30 miles blocks alot of horizon behind it."
So he thinks that a wave that is about as high as a domestic cat, when its 30 miles away is big enough to hide half a sky scraper.
There is no hope for these people.
Lol that is a great flerf proof
I have to correct you. Water vapour only has a minor effect on atmospheric refraction. The biggest factor is the lapse rate, or temperature vs. elevation. Also, he is correct that if your eye is exactly at sea level, half in and half out of the water, a 12in wave can block a significant height in the distance. The math with similar triangles is straightforward. However, his explanation fails when you take the camera to any reasonable elevation, say 5m or 10m above sea level, because as we get higher, the waves need to be higher and higher to block the buildings. There's no question that it's the curve of the earth, unless someone has an objection.
@@wiggles7976 "The biggest factor is the lapse rate, or temperature vs. elevation."
That's the reason I mentioned time of day.
"Also, he is correct that if your eye is exactly at sea level, half in and half out of the water, a 12in wave can block a significant height in the distance"
But that was not what he wrote. If a person wants to specify they are laying on a beach with their head half in the water they need to do that. What he wrote was without any qualification and implied standing at the water's edge. Or near it.
If you were laying on your side, head in the water you would not see any of Chicago's skyline at all, irrespective of refraction conditions.
He then went on to say that sometimes you CAN see Chicago's waterfront which I know is not the case.
The guy is the King of the Morons to suggest what he did.
@@ShizukuSeiji If he's specifically talking about that Chicago photo by Joshua Nowicki taken at the top of the sand bank (which they almost always are), then yes, a 12in wave is irrelevant.
I don't think you have a complete understanding of the refraction though. There do exist refraction conditions that would let you see all of Chicago's skyline laying on your side with your head in the water. Andrew Thomas Young tells us that these conditions do actually happen on rare occasion. A temperature inversion that causes a very steep air density gradient will cause light to bend with a radius equal to or less than Earth's radius. When it comes to doing these long distance observations across the ocean, you really need as many observations from the same location as possible to get the average result, and that's what I've collected and archived on my channel.
The real reason you can't see the waterfront is that light has negative weight, so it tends to bend away from the flat surface of the earth. The density of the air changes with the weather and the time of day, so the rate at which light drifts upwards also changes slightly-in some conditions it floats a little more than others.
No, I'm not serious, and I'm not a flat earther, but the intention is to illustrate that you can always add enough epicycles to “fix” an explanation. The thing that's missing with these people is not knowledge, but an appreciation of Occam's razor. Physicists are, to a lesser extent, the same: both relativity and quantum mechanics _tell_ them that space is not ℝ³-shaped (or even that topology), but they persist in using an ℝ³ intuition and adding corrections, rather than trusting the maths and working on the real question of how a quantum foam connected by information patterns _appears_ to be ℝ³-shaped at large scales-in short, not how locality is violated, but how it arises.
Having flown on Concorde I can confirm that when it was traveling faster than the speed of sound I couldn't feel any movement at all.

This evening, 2023-01-22, I observed a most spectacular sunset. It was partly cloudy; the Sun had just set; the waxing crescent moon was just 1.4 days old, and four planets were visible in the early evening sky. The western sky was aglow in oranges transitioning to shades of purple.
As I noticed each part of this beautiful sunset, the first thing that caught my eye was the magenta color of the underside of the clouds. The Sun had slipped below the horizon, yet its rays still illuminated the cloud bottoms.
Next, the moon was one of the thinnest crescents I had ever seen. It had the faintest glow inside the crescent. When I look at it with my 8x binoculars, I saw the Earthshine barely visible against the still bright afterglow of the sunset. Some wisps of clouds passed in front of the moon. As I watched them glide by, I noticed that the terminator was not as smooth an arc as the limb of the moon. Some lunar mountains were casting irregulars shadows in the lunar sunrise.
The planets were flitting in and out of view as the clouds moved overhead. Just above the crescent moon was the very bright planet Venus in conjunction with a much dimmer Saturn, though this furthest naked eye planet was still brighter than any of the visible stars in that part of the sky. Overhead and slightly west was Jupiter. Seen through my binoculars, I could also see three of the Galilean moons, which had moved a bit since my view of them the previous night. Finally, Mars was seen pretty much unobstructed by clouds in the constellation Taurus. It was a big red orb and much brighter when compared to either Aldebaran or Betelgeuse, which are its match in color.
Truly, this was a breath taking and awe inspiring view of the early evening sky. If you have partly cloudy or clear skies in you part of the world, I invite you over the next couple of nights to look and see what nature has wrought for our wonder and pleasure. Then ponder and ask yourself how this is even possible on anything but a globular Earth in a heliocentric solar system.
I live in England. Half of the time it's cloudy, the rest of the time it just rains.
@@RichWoods23 is that why the song "Mr. Blue Sky" exists?
Beautiful description sir
So I have a few things to add:
1. Flerfs cannot deal with more than one force acting on an object at a time. So, explaining to them that the centrifugal force and gravity act on an object at the same time will probably fry their shared neuron.
2. Flerfs don't generally believe in gravity, so I doubt they would listen to facts anyway.
3. At 2:58 you called Earth a "contained system". This will most likely prompt flerfs to say "AHA! So there's a firmament! You admitted it!", because they wrongly believe that the Earth is a snow globe, apparently. So, I would recommend you avoid such phrasing in the future, just to spare us a headache.
Otherwise, keep up the good work!
The 'one force at a time' is sadly true. I was trying to explain gravity to a flerf and his wonderful retort was to ask me why gravity doesn't affect a helium ballon.
@@juanausensi499
It’s usually a helium balloon or a butterfly since they all parrot the same memes.
@@juanausensi499 "his wonderful retort was to ask me why gravity doesn't affect a helium ballon."
plot twist: it does :)
@@juanausensi499 the question is so stupid, it's really sad. it's even more sad when flerfers tell us to not just belive in science but think about it but just parrot such nonsense like the butterfly argument...
@@juanausensi499Use this retort:
The balloon is lighter than air due to the quantity of helium. In any vacuum, even a home vacuum. And air pushes the balloon, but at a point it stops going up and is pulled by gravity.
Though they’ll give you a headache by telling you you just said “buoyancy” and “density” like that bible-ist Daniel that i debated with.
I actually did these centripetal force calculations for some Flerfs a while back, and transferred the same forces to a 6ft roundabout to demonstrate how fast it would spin to match the force of the earths spin. They then, as all flerfs do, moved the golaposts.
How fast did you come up with? Wild guess says something absurdly small, like 1 inch per hour, slow enough that those making the opposing argument feel really dumb :P
Edit: OK he basically gave this answer near the end of the video; that's what I get for commenting before watching 😂
If you could grow a pair of brain cells then you literally could understand that a car with bigger wheels will drive faster with same engine rotations. And 1040 mph at equator is pretty fast. 😅
Look a simple experiment. Even a one cell brain will understand it. You take a tripod with a camera and make wheel from a pipe. Stick some things on that wheel, or make some marks to be able to observe the speed. Spin it. Then take a longer pipe and make a bigger wheel and spin it again with same rotations per minute. How is the speed on the edge? Faster? How big is the floating in space and dark energy ridiculous water ball? A wheel with such radius will have quite Faster speed. And people calculated it by using the measurements given by "science ". And it's 1040 mph. 😅😅 snowing calmly today in Wisconsin.

@@rainbowwizard1821 that is simple math and logics. If it's to complicated for you then it's not my fault. And your answer is not even an argument. Which doesn't surprise me at all.
One more point about why we can't see the motion of Earth through space: not only are the stars we see very far away, but they are also orbiting the center of the galaxy at roughly the same speed and direction that we are.
Roughly. But we have evidence that our night sky changed during the last 2000 years. Another fact the flerfs love to gloss over.
We can see and measure the velocity of Earth with the reference of far galaxies actually

I dont remember why but 5 years ago when I was a sophomore in high school I was obsessed with flat earth for some reason. I argued with flat earthers on twitter for fun and I had no idea why I liked doing it. For my Earth Science final project, I learned that on presentation day I completely misinterpreted the assignment and decided last minute to scrap everything that I had prepared and instead stood up at the front drawing pictures and explaining how the earth could not be flat for at least 5 minutes. I got 95.
years later and Im coming back to this for some reason.

You used an example of pouring a drink on an airplane and I have an example similar to that. So I was on a flight out of Dallas and the flight attendant had just pour juice for me. The cup was on my tray table but because of turbulance that had started, I was grasping a hold of my glass. All of sudden plane dropped suddenly and I witnessed a good amount of juice come straight up out of the glass about about 8 to 12 inches above the glass and came straight back down into the glass without spilling and without hitting me going 600mph.

Two points…
1. To understand the ‘huge speed’ of the rotation of the earth, look at an analogue clock or watch and imaging the hours hand going at half speed. THAT is how fast the world is rotating … or the merry-go-round rotating half a revolution in 12 hours. Now would the be flung off
2. And in terms of why doesn’t gravity pull us down, and it is, this is why we have bones to allow us to now become a messy blob on the surface of whatever we might be above
According to flath earth logic: The pressure at the bottom of the pool should be the same as at the top. Water density at the bottom is the same as the top.
Try asking this from a flerf….. I tried and I could never get an answer, but I got a typical flerf response of talking about some other nonsense sh$t that has also already been explained/debunked….
Lol 😆 there is no top or bottom (gravity) but stupid people will always be
Because Flat Earth stuff is complete bullshit, they always just toss out key concepts and then pretend that makes their "theories" valid.
It's always an absurd over simplification of a complex system, then pretending that nothing was lost in that simplification.
omg, which flerf thinks that? Oh i know the ones that experience the bends whenever they go diving.
@@doncsicso81 No flerf does ever answer anything. They just jump from topic to topic like someone with serious attention problems.
My favorite comeback to the "You believe in the spinning ball" framing is to say "Well you believe we live in the dome-shaped room." Which sounds even more ridiculous and is probably about as memeworthy. That's not a scientific comeback of course (which would be easy) but it kind of helps to turn a silly meme back on them sometimes since the kinds of people locked in this paradigm are probably kept here more by some kind of social pressure or social bias rather than an honest appreciation of the facts.
The "water doesn't curve" argument gets me. Have they not seen water floating in little orbs in zero g? I wonder how they'd explain that.

@@RichWoods23 It took 4 hours for each frame from Toy Story 1 to be rendered. Each CPU that rendered the movie had about 27.5 million flops, and all the cpus combined was about 8086 million flops, which is the strength of a Pentium CPU. Why is this relevant? Well, the strongest computers NASA could use for processing were giant, bulky mainframes which could do 16.6 million instructions per second, which is likely around the same amount of flops those computers had.

I've tried explaining that earth rotates twice as slowly as the hour hand on a clock. But they didn't seem to know which hand that was.
This is exactly why flat earth needs to be taught at school - to thoroughly debunk it and make science more relevant. Of course, more than anything, flat earth shows a failure in our educational system. Well done explanation: concise and to the point.
No the people who believe in the flat earth have failed themselves cause they didn't pay attention in class, to realize earth being flat is not someting that is possible and they arent a scientist cause they are too lazy to actually do real science and believe what their constant tests to prove the earth is flat is wrong, again and again.

Thank you for indicating the force, although I think that you presenting it in Newtons will likely confuse most flat earth proponents. But, if they look at 8:14, it also shows the acceleration as 0.031334m/s^2, which is at least 300 times less than the 9.81m/s^2.
And when you consider that these forces are acting on your body simultaneously, that means the force they expect to feel would just alter the overall feeling of being pulled down, instead of experiencing 9.81m/s^2 it would be about 9.78m/s^2. It isn't something anyone would be able to feel with their senses.
Exactly! And thats why if you got weights and measured them at the poles compared to the equator, there would be a difference in calculated weight! Even though it's the same weight and measuring tool/scales.
Considering flerfers are confused by spheres, one of the simplest objects in the universe, presenting force in Newtons (instead of dynes or pound-force) is most likely immaterial 😁
@@shuggiemcg1 indeed, and Bob the Science Guy did a whole video bout a road trip, two 500 gram weights and one scale to prove this 😉

A minor correction: there is no absolute frame of reference. All velocities are relative to something else. The stated velocity for the Sun is relative to the galactic centre. The galactic centre is moving relative to the local group…

I like to say half the speed the hour hand moves on an analog clock. They might, just might be able to visualize that, or have one to actually see.
@@Tsudico that's what I use too. I've challenged geoflatniks to look at the hour hand and let me know the moment it moves. Still waiting ✌️
The r line of argument I like to use against the flerfs here is angular velocity. When measuring how fast something is spinning we don't typically give that a speed in ft/sec or mile/hour. We measure rotational velocity in deg/time. In the case of Earth we rotate at 15 degrees per hour and 360 degrees per day. When flerfs say things like "spin a merry-go-round at 1000mph" they're misunderstanding this concept. If they wanted to use a merry-go-round as an analogy for the Earth they should spin it at 15 degrees per hour. What they'd notice is that the merry-go-round is barely moving because it's so small.
Great video, and great graphics!
" If they wanted to use a merry-go-round as an analogy for the Earth they should spin it at 15 degrees per hour." - This is also incorrect. What you need to do is keep the centrifugal force the same, and that depends on the radius as well as the velocity (whether you angular velocity or instantaneous linear velocity).
@@stephenandrusyszyn3444 sure, if you wanted to keep the forces the same. Dave already explained the underlying forces brilliantly. My point is more about how flerfs will often scream "1000 mph" in an attempt to say we should be feeling it if we're moving that fast. My point is that you can easily show exactly how slow the Earth is actually turning by demonstrating the angular velocity on a merry-go-round. Not to replicate the force, but strictly to show that 15 degrees per hour is slow, and the only reason you end up with a tangential velocity of 1000 mph is because the Earth is large. It still is rotating very slowly though, and there's no reason to expect us to feel a 15 degree per hour rotation. That's all.
@@coleford4258 And my point is that shouting "but it's only 1 rotation per day" is just as bad as shouting "1000 mph". Both are meaningless arguments.
@@stephenandrusyszyn3444 Yes, you are right.
Assuming a 2 m radius and standing at the edge would require about 0.15 rpm (or about 7 minutes for one revolution) to experience to same centrifugal force as at the equator. I.e hardly noticable.
@@stephenandrusyszyn3444 I disagree. The rotation would have a noticeable effect on centrifugal force before a change in radius would much like what twallgren is pointing out. If a flerf is upset because 1000 mph seems like something they should feel, then a reasonable argument would be to focus on the angular velocity, and demonstrate how small that rotation is. You could then talk about how the change in radius will only have a very minor effect on the centrifugal force, but in my experience flerfs go catatonic when you actually start looking at numbers/equations.
But if you still think both things are equal and silly then you're entitled to your opinion.
Also, if the change in speed is gradual enough, we won't feel that either. Like if the earth speeds up a few mph over the course of 6 months, we would never know the difference.
Yeah, someone recently argued that with me, that "why we don't feel the supposed change in earth's speed", so I calculated the change and it was like 0.0xx km/h² change, which is something, that not even most precise accelerometers would catch.
@@mabed6692 Yup, we can't directly feel the rotation of the Earth, but they think they should be able to feel the changes in velocity in our orbit around the sun and galaxy to which are far larger in scale?

People are measurably squished by gravity: When you wake up, you're one or two centimetres taller than in the evening after the entire day of walking around. Gravity compresses the spine when you're upright.
Earlier space station man had a twin who stayed on the surface and when he got back down they were put through extensive medical examination to get a good reading of the effects of prolonged zero G exposure. The clearest difference was really evident at a glace, the man came down almost a whole foot taller than his twin.

So I got the foot taller part wrong apparently, but still the height you gain without G forces squishing you down is crazy.
Simple, and straightforward - which is why Flerfs will ignore it or attack it.
Obviously flerfs won't listen, but hopefully this can catch people on the fence. Info like this can take the power away from the lies of flat earth charlatans. Nice work!
Air pressure is a good example, actually. Generally speaking, we live under 1 bar of pressure - which is actually quite a lot. We don't notice this because our bodies are have evolved to function under this pressure, but you do start to notice when that pressure begins to go away. Similarly, air resistance is something we don't notice in real life. We move around seemingly unimpeded, despite moving through a somewhat dense fluid. If you don't believe me, try to slam the door to a sealed room (with all the windows and doors closed). You'll notice a significant rush of air cushioning the door.
In fact, I have a sealed hallway in my house. When I open the door to it from one room, it causes another door to rattle and sometimes be pulled open if it's not closed properly. Air may be stretchy, but there's enough of it with enough density to keep doors from slamming and pull doors shut. Yet we normally don't notice that we're fighting this sort of drag because - like you said - we know nothing else.
Flat Earth: teaching people about science but for all the wrong reasons its adherents believe. Well done.
Have to agree. I have learnt so much from this debate, and very quickly realised the flerfers are all insane. Many thanks to this Dave, the other Dave and Dan, amongst others, for tearing these idiots a new a-hole!👍

me: how aren't we throne out of a plane, which is spinning (according to your theory) at a speed of a thousand KMPH around the north pole?
Because they believe the ‘flat plane’ is stationary and the local sun & moon move above us a few thousand miles away.
@@kernicterus1233 I think the point being made is that an aeroplane flying, at a speed in of near 1000kph and on a constant course either due east or due west would be constantly turning, therefore the same force that would throw us off the globe should try and throw us out of the plane.

I've many times been on a stationary train when the view of another stationary train on the adjacent track moves sideways. It's often difficult to determine which train has started moving.
As a train driver I can attest this is true. We’ll sit in a yard at a red light waiting for our departure time, with another train beside us waiting as well. You can be reading a book or something and out of the corner of your eye, the other train will start to slowly move off having got a green light.

Dave: There been a lot of flat earthers............
Dog: Oh no, not again....leave it Dave, let it go!
I imagine all of your previous videos (amazing btw) debunked many of their talking points, so they reverted to “you can’t stick to a spinning ball, do you really believe we’re rotating, orbiting the sun, traveling through the Milky Way, and flying through space, yet, DONT feel it?!” Insufferable
flat earthers always ask that question, not realising that the earth spins once... a day.
It's sad that so many people can get confused by big numbers without asking about their context. All the information is there, but the big number effect just seems to stun people into disbelieving.
Excellent explanations in this video ! This makes it really simple to understand !
Slight nitpick, you mention that the earth is moving at 490k mph through "absolute space" even though there is no such thing.
If I am not mistaken, that number is our velocity around the center of the galaxy.
Great video!

The only time we would be flung off the earth is if it suddenly stopped!!! Our inertia, being disturbed, would result in us being sent in the same direction we were travelling previously. Much like standing room only on a bus. Whilst the bus is travelling forwards we are able to stand still - if the bus suddenly screeched to a stop we (as I'm sure many people have experienced this) would be thrown forwards. It's also the reason we have seat belts in a car
That is not right. Inertia is always making you try to go in the same direction, that is what the centrifugal force is (appears to be). If the earth stopped turning that force would go away.
@@briansomething5987 You must have misunderstood what I meant. Inertia is the state of "doing nothing" until an external force is applied. In my examples, 1) the earth suddenly stopped so the inertia of being still (relative to the earth) was dramatically changed any you would be flung off the ground - same in example 2) on the bus. You are in a still position whilst travelling at speed with the bus and only when the brakes are suddenly applied would you be flung forwards because your inertia is disturbed. I will amend my original comment to reflect this
It's the reverse argument to why we don't just bundle all of our unpleasant nuclear waste into a satellite, & simply fire it into the Sun. After all, it's just 'over there', and the heliocentric model says that the Sun has massive gravity, and pulls everything towards it. That would be true if the satellite were stationary in the solar system frame of reference, but it isn't, it has the same linear velocity as Earth in its orbit around the Sun [ that 67 000 mph number ]. If it remains at that speed, it will become just another object orbiting the Sun, so that speed has to be lost through retro rockets, or similar. The amount of fuel involved becomes absolutely prohibitive.
@@NJM1948 No, that is still not right. The 'inertia' you are talking about is tangential to the earth. It is constant, and the force can be calculated (as in the video). If the earth suddenly stopped moving you are not going to GAIN inertia. You would not be flung off the ground. You would just get a slight bit heavier. The difference between a sudden top and a gradual slowing just determines how quickly you will get heavier. A sudden stop means you would get heavier quickly.
@@briansomething5987 you need to google the terms you're using... you're wrong. You have momentum at your current angular velocity. If the earth stopped, you don't stop with it - just as if you're in a car and the car hits a brick wall, you don't just stop because the car stopped, you're thrown into the car because YOU ARE STILL MOVING. jesus you're thick.
The statement was "The only time we would be flung off the earth", he didn't say gravity stops existing, and your understanding of inertia is hilarious. Inertia is the tendency of an object in motion to REMAIN IN MOTION. Inertia is not gravity, you would not gain inertia, but lose inertia as you decelerate After the earth stopped -> side note, losing inertia causes a loss of mass (get lighter)...
You know that term "From your lips to God's ears?" I kind of think that applies here. That was an extremely well thought out and amazingly articulated explanation of 5th grade science, and I enjoyed watching it very much! But it will all go in one ear and dribble right out the other end with flerfs! For them, you could have probably stopped at hello. Every word after hello will be too complicated for them! It's kind of like trying to explain tensors to my dog. You might be able to explain it in a way that even a dog could understand, but in the end, you will just get an extremely blank stare! And maybe a cute woof because you are talking to them.
But please keep posting these! I love them! And maybe, just maybe, you might prevent a couple of almost-flerfs from falling off the edge of the disk! 😄

i think the explanations are more for ppl that seek for information whichever flat earth is something to consider to be more than just a phantasy or not. flerfers won't acknowledge the explanations... so i really can understand what creaky is doing, i started calling flerfers also by what they are, idiots, bible belivers (christian fundamentalists if you wanna be very critical) or just con-man who earn money by making YT vids or other stuff. it's just in vain to try to explain how wrong their believes are...

So the comparison between him who demeans them and gets information wrong all the time is a massive contrast with this guy who avoids demeaning them and makes sure he's putting out there the correct explanations for the phenomena the flerfs are questioning.

Stupid.. earth is flat... Aeroplane fly over flat earth.
Here you saying air pressure do the adjustment, some say gravity do the adjustment, some say aeroplane do the adjustment by gyroscope..
Blsht... imagination..
Earth is flat
Aeroplane don't need to specifically adjust for the earth curvature since it's so minute, any other adjustments the AP make will incorporate earth's curvature over a period of time. Also, it's like cruise control of a car, it's never perfect, but work within an acceptable margin of error, so if you've set your car to cruise at 60mph, it's almost never exactly 60 mph, but will go up and down within a few mph of error, just like an aeroplane's autopilot.
@@shayamaldolai Air pressure does the adjustment. Planes fly through the air. When the plane is in balanced flight, the lift (largely due to the angle of attack) equals the downward force of gravity. Hence the plane maintains its altitude and follows the air pressure around the globe.
@@shayamaldolai Hey you should troll somewhere else
@@shayamaldolai I'll answer all of your questions, then you can try to answer mine.
1) The plane altitude thing doesn't seem like a bad argument at fiirst. However, there is one issue with it: the very way airplanes work in the first place. They need a constant jetstream of airflow to keep their altitude and/or speed. You seem to be pretty smart, so I think you understand how aircraft work.
The airplane, will, however, always level out on its own. As it moves in a relatively straight line, the atmosphere gets thinner. This causes the plane to lose its speed. If it, however, loses speed, it will no longer achieve a big enough airstream to stay afloat; if the pilots keep pointing straight, it will start to lose its altitude again.
Shortly put: because the atmosphere is getting thinner and thinner the further away from the center of the earth you get. They simplay cannot keep flying straight, as an aircraft needs a minimum of air flowing under its wings, etc. to fly.
If you'd try to keep going straight, the aircraft would simply start to stall out and lose altitude. You can ask a pilot about it: a plane simply has a point beyond where it cannot climb as the engines have a limited amount of thrust (which also needs air to work).
2) Different atmospheric layers are, technically, indeed moving at different speeds. However, the air is a) a gas, so it isn't really connected to itself and simply makes up for the rotational forces by moving the upper parts at slightly, and I repeat *slightly* faster speeds. Besides, as the atmosphere is getting thinner, the air has more space to expand to. And no, a vacuum doesn't suck things into it. That "phenomenon" only applies to gases to which the same amount of force is being applied to. Ask a physician.
Then, keep in mind that the atmosphere is obviously spinning with the earth. This video has done a pretty decend job at explaining why the earths rotation does indeed not "just" throw us off of it, which also applies to the atmosphere. Otherwise, we would constantly be feeling winds moving at ~1000mi/h,which would not be pleasant or physically explainable.
It follows that aircraft don't have to adjust their course in order to flyin a straight path.
You can also imagine this in a different way: Everything (on earth) is rotating around the (imaginary, just for simplification as, technically, every atom excerts a gravitational force) axis at the same rate; not speed, but rate (=it takes the same amount of time for a 360° rotation). It follows that no matter how far up [in the atmosphere] you are, you won't be feeling any of the rotational energy.
One thing that I've never seen any "flerf" acknowledge is the preservation of energy, a.k.a. the fact that as long as a movement is not being stopped; it will continue in the same direction. As the earth is already spinning for a v e r y long time, everything has synched with it and therefore, only the rotational energy remains. The reason this force does not "throw" us out into space has been explained in this video so I'll spare you that bit.
Oh, and I'm not a bot or anything. So I'd like you to first debunk my statements before opening new layers of the argument. Otherwise, things would quickly get out of hand.
I'll wait. ;)
Oh....I am now spamming you as well. Just answer.
To reiterate what he showed:
Centrifugal acceleration for an 80kg person on earth: .03 m/s^2
Centripetal acceleration (gravity) for everyone on earth: 9.8 m/s^2
The centrifugal acceleration is just over 0.3% of the centripetal. And that's at the equator, where the force is maximized. At 40 degrees latitude (roughly where NYC is), the tangential speed is down to 795mph. That leads to a centrifugal acceleration of 0.009206 m/s^2, or just .09%.
Yet flerfs claim we should be able to feel it.
Indeed. That's why if you calibrate scales on equator they will show different values for same weights, when then brought to e.g. Canada or down to Australia.
@@mabed6692 Yup. Greatersapien showed this in one of his videos, and the great thing is that everyone has the ability to do this. Of course flerfs ignore all of that, but that's just par for the course.

Are you kidding? There are adults today who don't know why they don't fly off the Earth?! OMFG one would have to be brainless to not know.
So excited for your videos every time they show up in my feed!
In regards to experiencing different environments, Denver is around 3 times higher in elevation then where I live. On my first visit there, I had near constant nose bleeds due to the difference in air pressure.
The difference that elevation can make to some people is astonishing.
When we were kids we loved going up the mountains. Going up 3500m the thin air is clearly noticeable. Be it just from breathing, the tires of the car being a bit harder, closed bottled bulging up (and whatever you do - do NOT open them inside the car) - it is noticeable. We kids didn't care but out mom really had trouble with that, getting several day-long headache.
The other way around is used in sports. Training at higher elevations to get the body used to the lower oxygen-intake (the lungs need pressure to be able to take in oxygen from the atmosphere) which the body counters by an increase of red blood cells. Going back down for a competition will then have the athletes being able to take in more oxygen more efficiently.
Even though I am not a flat earther, I like learning

I'm an ex flat earther. I managed to escape the delusion. Although quite rare. We do exist.
The problem is flerfs have a myriad of business models and they have no idea of which one to agree on. Of course the emphasis is on "no idea".
So simple ideas that anyone with a High School elementary physics class can understand. Thanks for such a great video. If you check the profiles in, say, FB, of people who think we should be flying into space because of Earth’s rotation, you will find they have just a HS education, but aparentar they never took physics or weren’t paying enough attention in their physics class.

That sort of claim is not new though. Way back in the 19th century, people thought that passengers traveling in a train at over 20 mph would suffocate, because they'd be moving too fast to be able to pull air into their lungs.

The Bond girl Mary Goodnight is locked in the boot of Scaramanga's car and 007 is giving chase, when Scaramanga famously drives into a garage and converts the car into a light aircraft. He takes off and escapes. However, Goodnight uses her walkie talkie and tells Bond that she thinks they've stopped somewhere. So she opens the boot and is shocked to find herself up in the air. She had no external reference frame to measure against and so from her perspective she wasn't moving.
another example of relativity: calling a trunk a boot
😝
It's what James Bond would call it... 🇬🇧😉
Your videos are often ones I regularly come back to because the way you present them is incredibly digestible even to someone who doesn't do much of their own research into these topics. The information you share is in depth but still easy to understand, which I can appreciate. Keep up the good work ^^
My favorite go to for the earth spinning on an axis argument is that it's not a very fast spin if it takes a whole day to make it around once!
1000mph is still 1000mph….. doesn’t matter how long it takes to 1 rotation or how big the earth is
@@jamesstringer604 tell me you dont know how rotation works without telling me you don’t know how rotation works
@@jamesstringer604 Oh it matters not! If it takes you 1 day to spin around a merry-go-round, you won't feel it move. QED.
Slower than a clock hand but flatearth morons no this but it destroys there religious belief B.S
@@ExistenceUniversity if you claim the axis, the the globe stays in a fixed angles position, that define north and south, top and bottom and so on.
I’d like to see a livestream of Australia at the bottom of the ball, with people and buildings upside down
I know the earth is an oblate spheroid , rotates on its axis and revolves around the sun which orbits the galactic center. What puzzled me is how the centrifugal force from these rotations is insignificant. Thank you for this explanation.
How do you know all that? Do you have proof?
Can a basketball have fixed axis?
lmao
a flerfer asking for PROOF?
give us a break mate! our sides can only split so far!
😂😂😂
@@Globeisahoaxx I know one thing you don't have proof of the 'edge' or the the globe walls that Artemis penetrated or you would present it. 👶😭
@@Globeisahoaxx Can a basketball have a mass of 5.972.000.000.000.000.000.000.000 kilograms and a radius of 6.371km? No? Thats why an basketball can't have a fixed axis.
Easy comprehensive explanation The 3rd derivative of Displacement. Which coincidentally describes most adult Flat believers
I hope I'm in before a flat earther hearing "a contained system" and commenting "AHA! A CONTAINER!"
You are, unfortunately not before that happened
Earth big....moves slow.....we are tiny.....
who was expecting the clip of "a 15 degree per hour drift" from bob and wanted to thank him
✋
Don’t.
He’ll then end up worrying about giant inflatable bananas.
This is the best discussion on this topic I have found on RUclips, and someone finally explained it how I have always thought, it’s not about speed it’s about distance traveled compared to size
I keep being impressed with how well you do this. Well done!
❤️❤️
Sometimes, I think flerfs are just trolling us. I mean, they can't really be that dumb can they?
@Wonder777 so, you think that we were tricked into believing that the earth is a sphere, correct? What is the purpose of this deception?
@Wonder777 I see by your comment that your are challenged by the shear size of the Earth compared to a human being. You are under appreciating the comparative scale of these two.
Do a little math before deciding if a human being can directly observe the Earth’s curvature.
@Wonder777 Disproven how? The Earth’s curve drops off 8 inches per mile? And your proof is because you can’t see this with your naked eye there is no curvature; therefore, the Earth is flat? How perceptive of you.
Let’s take your figure of 8 inches per mile. That’s 2/3 of a foot per 5280 ft. That’s a slope of 0.00012626. Can any human, even the most sensitive of humans, resolve this slope value with their unaided senses? Can you? If so, that would make you the most perceptive human in all of history.
