The Earth is Definitely Not Flat 

- Your documentary about the Flat Earth has received an international movie award. - What award? - The Golden Globe.

Anti-Flat Earthers: STOP COMMENTING!! I can't find the Flat Earther comments to laugh at them!

I used to be a flat earther for three years. Then I turned four.

I find it hilarious how the ancient Greeks found out the Earth was round based off of the shadows of pillars. Now we have satellites, rockets, and other forms of viewing the Earth from a God’s eye view and people still think the Earth is flat

A flat earther dies and is waiting at the pearly gates. St Peter says to the man, before entering heaven you may ask God one question. The man asks God , is the earth flat or a globe. God replied, the Earth is most definitely a globe . The man exclaimed, holy crap , the conspiracy runs deeper than I could have ever imagined.

Professor Dave went from teaching kids-teens about chemistry to teaching middle aged men basic astronomy

Just converted my long time flat earth dad with this video. 🙏 thanks Dave! There was nothing I could say to convince him until I showed him this. You have no idea how satisfying it was to hear him say “yea you right… it’s round. There’s no way it’s flat”

Everyone just says flat earthers "are idiots". I took the time to listen and understand what they believed and I've come to the conclusion that indeed they're idiots

I kinda appreciate flat earthers only for the fact that I've learned so much more about the earth when their stupid theories get debunked

Anyone else looking through the comments to find stupid flat earthers comments?

I love how dave started off one of the most ruthless annihilation of a giant scam with a very good faith video aimed to educate people. The flat earth’s said lets go to war, Dave said, “this isn’t war, its pest control.”

if you think you're dumb, just remember flat earthers exist.

when you breathe the atmosphere and not the atmosflat

Asked a flat earth women if she'd like to dance. She said no because she refused to believe we were at the ball.

“Rather than mocking them,” he says, immediately aging this video. Seriously, we love Professor Dave’s savage mockery of these idiots.

Professor Dave wasn't kidding when he said that he already tried the nice guy approach, the "meaner" tone he uses in most of his other flat earth videos makes perfect sense.

"They're evolving, just backwards"

scientists in 1900's: we just discovered that their are particles beyond neutrons and protons Scientists now: For the last time, the earth is *round*

"Goes to comment section, sets comments to newest to look for flatearthers"

Honestly I love how Professor Dave just uses this means to draw out the flat earthers so he can roast them. I both respect that and find it extremely entertaining.

One of his videos was shown in class. I assumed Dave was just another school teacher boring channel, and then i stumble upon this, holy shit. Didn't know Professor Dave made a living off of curb stomping flat earthers with logic and steel capped boots

NASA should release a "photo of flat earth" and get them all excited that they were right, then come out a day later and say it was photoshopped 😂

Dave, I need some mental support. I debated with a flat earther for over a week, giving him mountains upon mountains of evidence, explanation after explanation, challenge after challenge, but in the end, he was still adamant that the Earth was flat. And it seems to me like there is no shortage of these people. Please tell me that there is still hope for mankind to live past this century?

I can't get over the fact that a group of folks who, mostly, are terrified of the UN...use their logo as the flat earth map...

The video that triggered flat Earthers all around the Globe!

Cant believe I had to do this, but I gotta thank you. I have a friend who I always knew was on the dimmer side, but I didnt learn he believed in the flat earth until a few weeks ago. I found this video and showed it to him. He is actually pretty good at math and such, so he checked over the (very obvious) things that you stated in the video. He is no longer a flat earther, and frankly feels stupid for believing it for so long.. Now I just gotta convince him the moon landing was real imo. Thank you though, helped out a lot man.

If the earth is flat why is there no bedrock I you mine like 5 blocks under it, and also where are all the slimes spawning?

The earth isn't flat or round, it is the shape of a dino nuggie duh!

When I was a teenager I was like a joking member of Flat Earth Society, not because I really believed the Earth is flat but rather because I just found it fun to try to come up with increasingly convoluted means of explaining phenomenon on a flat world. I had no idea for years that people really believed this shit.

POV: you're trying to find the flat earthers in the comments 💀

Here's my question if the Earth flat, why would everyone lie about it? Why would governments lie about this? What do they gain from tell you the Earth is a different shape?

I was talking to my alien friend, and I told him "I guess we're not as advanced as I thought. Some of us still believe the Earth is flat." He turned to me on confusion, and said "But the Earth IS flat..." ...Damn fourth dimensional beings...

It is still unbelievable to me that people really believe in flat earth

I like how this guy sounds slightly annoyed that he has to make this video😂😂😂

Additionally, if the Earth is flat, where are the edge of the world tourist traps?

It's comical how much damage control they had to put out when you uploaded this.

Ah, young, innocent Dave. To think you once thought this was simply about the science. If only your younger self could see you now, wielding knowledge and logic like the sword of Damocles, protecting our little blue marble from the flat Earth menace.

"Outside the box" thinking is one thing, and is always encouraged. However, 'outside the brain thinking' is called "CRAZY."

Just the fact that there have been no whistleblowers and the government would go through so much effort for something so pointless to our everyday lives is enough to destroy the theory

I had my education up to high school in Hong Kong for 18 years, I then moved to the US to continue my studies because why not. One day I had the idea of asking my friends in the US of what they thought about the earth. Surprisingly, 2 of them arent convinced that the earth is round. You know what I did after year 1, I returned to Hong Kong.

Dave- “But what is up?” “Hey Vsauce, Michael here.”

It is so fun to go back and watch this first beautiful and clear flat earth video in Professor Dave's playlist done in the innocent and friendly style of his other pedagogical videos. To future people: watch the gradual progression of Professor Dave on this issue as he butts heads with the flat earth and pseudoscientific community, particularly during the COVID era. It is like watching the Great Cthulhu awaken from its long slumber. It is beautiful and terrifying to witness in its own right as Professor Dave eventually just takes the gloves off and pummels relentlessly with Science.

The follow up to this video is still the greatest flat earth debunking video in all of RU-vid.

I have never seen an comment section/ a RU-vidr so active on an 3 years old video. That really impressive Professor! Keep it up!!

Let me guess, you're also looking for angry flat earthers

Can you explain where babies come from? I'm still stuck on the stork theory. EDIT: Apparently my parents were lying to me this whole time. Babies come out of the belly button. MIND BLOWN

Its incredible to still see Dave replying to every single new flat-earth comment on this video absolutely annihilating them with words

If I may, we’ve known it for a few millenaries, not a few centuries. The earth being round is not a modern discovery.

Some comments helped me realised that common sense isnt actually that common

I used to think the earth was round, but then I did my own research, and I still do.

The fact that this even has to be explained in this day and age is insane.

“Winning an argument against a smart person is hard, but winning against a stupid person is impossible” -Abraham Lincoln (probably)

True ignorance is not the absence of knowledge, but the refusal to acquire it.

I love how in their mind an american company controls antarctica. When america was founded, spherical earth already was proven - its discovery was based on it.

I seriously pissed off a Flat-Earther not long ago during an online debate. He actually blocked me, and then left the debate saying, and I quote him "F-U guys, you tricked me to coming here". LOL Ok, here was what I'd done. I put up a set of four flat-earth maps and asked him to pick which one was the correct one. Which he did. Then I asked him to explain how the sun and moon caused day and night. THEN I asked him, "Ok, on this same map, how do solar and lunar eclipses happen? And he began to stammar and haw and go "they don't exist, it's a hoax, a conspiracy, " etc... and I said politely "Sir, we see them all the time, one is coming up in a couple of weeks, a solar eclipse. If what you say of day and night cycle is true, then how can this happen? And he immediately blocked me after a few nasty choice words and insults.

As a Christian i cringe when flat earthers say Bible says Earth is flat.

Does it annoy anybody else seeing how flat earthers go out of their way to combat actual science but don't put an ounce of that same scepticism toward their own arguments? No matter how crazy it sounds?

It's so sad that we even have to explain this, in the 21st century.

The older flat earth concept is far more interesting: a flat earth rests on 4 elephants standing on the shell of a turtle.

it fascinates me that people still try to argue that the world is flat

question for flat earthers - *why are there no pictures of the other side of your flat earth?*

I find it hilarious that every Flat Earther won't believe any scientist of professor, but will believe any conspiracy theory on the internet 🤣

Dave I have a question. My mother is a flat earther and I tried as hard as possible to disprove her. I told her everything I knew, told her about timezones, lunar eclipses, day and night cycle and much more. I showed her all of your videos and she said “all myths, he’s a professor so he’s in on the secret to hide the truth from you”. She even destroyed my mova globe (which is extremely expensive, and you can research about it if you want). Could you please help me change her little brain dead mind? Also funny how they tell us to not believe the government, but they believe the same conmen on RU-vid (her favourite is FlatEarthDave). Could you please help me? I’ve already done so much research. And I swear I’m not lying to you and please don’t roast me lol.

Flat ❌️ Sphere ❌️ Donut ❌️ Bumpy Oblate Spheroid ✅️

Aliens : Let's check up on humans. Humans: The earth is flat. Aliens: They're going backwards!

The flat model looks like a pretty snowglobe! Do flat earthers think that when it snows it's because God gives it a good shake?

Proffesor dave, I have a small challenge for you: Every time I try and prove to my flat-earth dad that the earth is a sphere, every time I tell him something that he doesn't have an explination for, he just replies with " one day we will know how that hapens". Ex) if I show my dad that the moon clearly does not work on a flat earth, he just says " one day we will know" What should I tell him?

If the earth was flat Australia wouldn't be called down under, it would be called over there

Once had an older friend who was brilliant but had formal education only through elementary school (in the 1910's). He had unparalleled knowledge of human nature but knew no science. One day he argued for flat Earth based on the following argument: "Let's say I leave my house, go have a meal at a restaurant, a drink at a bar, and have sex at her house with the cute girl I picked up, and come home and my house is still here. If the earth moves, how is that possible?" He was utterly convinced by my counter argument: "Let's say you are in your seat on the train going from LA to Chicago. You go have a meal in the dining car, a drink in the club car, and have sex in a berth in the sleeping car with the fine woman you met. Then you go back to your seat and it's still where it was when you left. Does that mean the train didn't move?" A light went on in his head and he understood. At the age of eighty he became an eager science student, learning everything I could teach him. He lived to 101, getting to see the new millennium, having been born in the last few days of the nineteenth century. Rest in peace, Tony.

the solar system according to flat earthers: ⚫⚫__⚫⚫⚫⚫⚫

Idk why I love rewatching all your disproving flat earth videos. It’s weirdly calming and it makes good background music. The 1.7M views are just me rewatching it over, and over, and over again

If you see my comment, you are probably looking for flat earthers but setting comments to newest.

Its a shame, that there are about 25% thumbs down. Are people really that stupid??

Flat earthers are just 2D people who will never understand the concept of 3D. XD

I’ve become fascinated with your channel over the past few weeks; thanks for such high quality videos!

Love your videos! I take inspiration from your debunking and also make popular videos.

How to trigger a flat earther 101: Ask Questions

If you're looking for flat-earther comments, sort by new.

The fact that dave still responds to these comment five years later brings me great happiness

When I try to discuss this with my dad, you can never say the word gravity because he completely believes it doesn't exist, he believes the law of density keeps us down. But there is a pretty good explaination for why it isnt the law of density.

I once listen to a woman who said: "If the world isn't created by God, then why does it take exactly one year for the earth to go around the sun?" - You know, even if people accept scientific observations, they still can mess it up terribly.

This is brilliant. Thanks. As a science teacher, I try my best to instill scientific literacy into my students. It is so important that our youth grow understanding not only how the natural world works, but more importantly, how to question and problem solve without bias. I was just thinking, I bet there are not any Astronomers, Astrophysicists, Rocket Scientists, Planetary Scientists, Meteorologists that believe in the flat earth. There is no mathematics in the flat earth model that would allow a rocket to travel into space, to use the gravitational pull of the earth for acceleration, and to reach another body in space.

I love how if he sort by newest first you can just see professor Dave roasting flat earthers

A solar eclipse shouldn't happen if the earth is flat. Why does the moon block the sun if they are "circling around us"? Does the moon just go under the sun and create a shadow or smth? I think we all have common sense to know the Earth is round, just some people are convinced they're special and want to be distinct by being away from the truth. Good video, keep it up

Aliens: let's check up on the humans Us: the Earth is flat Aliens: I thought they got past this level centuries ago

I'm a hobby (astro)physicist but psychologist by trade and I thought of a psychological model to go with the flat earth society and why it is so much more prevalent in very meritocratic societies - i.e. the USA. A large part of US culture is Calvinistic in essence saying with hard work come more blessings. This translates into the "American Dream" where anyone can become anything regardless of heritage only depending on their own talents and efforts. Unfortunately this also puts a lot of blame on those who, well, don't get very far on the social hierarchy. The mind is wonderful at compensating for negative thoughts and emotions, rationalising them away unconsciously in amazing ways. My hypothesis is now, that most flat earth followers are a special type of narcissist personality who fail to reach a societal level they think they deserve. You can then either reevaluate your self-image (which is painful) or you re-evaluate society. By subscribing to a conspiracy theory you not only elevate yourself to an elitist, enlightened level only attained by few, you also simultaneously degrade every person that you previously had to "look up to", e.g. academics, politicians and "smarter" people. Furthermore, you find others with exactly the same mindset and company is always good. That is also the reason why challenging any flat earth follower with rational arguments will most likely amount to nothing, because following your logic they would have to challenge their self-image and re-evaluate their social standing. And the unscientific part of me relishes the thought of a perfect trap where you either have to get down to the bottom with your argumentation or admit you fit into the diagnosis of an anti-authoritarian narcissist... But that is really just a side note.

It is truly baffling that flat earthers exist in this day and age. I am amazed at your patience and knowledge.

The flat earthers look at all of our science and discoveries and say "nuh uh"

Scientists before flat earth: every year making new discoveries Scientists now: FOR THE LAST DAMN TIME THE EARTH *IS NOT FLAT IT IS A SPHERE*

I was never taught or ever believed in flat earth, but I can't believe I've learned more about geography, physics and astronomy from flat-earth-debunking videos than I did in school

My favourite part is that they have no answer for what the benefit of this conspiracy is.

So they say there is no gravity. That the earth is constantly moving upwards. Then what keeps the earth from smashing into the sun and moon? Are they also being projected upwards? What keeps the sun and moon anchored? If there were no gravitational force, they would just float off into space.

Hi Dave. I just found your videos a couple days ago, and love them. You have an amazing skill at explaining science simply and clearly. Thanks for all your videos. In this day and age of growing pseudo science, we need them! I'm looking forward to wearing the t-shirt I ordered.

I love this comment section. It is so entertaining. We also have a flat earth community in Germany. But it is nothing compared to your experts in the US. I could listen to them the whole day. It's just fascinating to see, what can happen to a physical healthy brain. Greets from germany

To flat earthers: 1. Show me a picture of the edge of the earth. 2. Look at a normal picture of space. 3. Attatch a camera to a weather balloon, and review the footage after the ballon pops. 4. Show me what the bottom of your "flat earth" looks like. 5. Have common sense. 6. Try to learn a bit of science. To round earthers: Nothing, you are all right about the shape of the earth!

I'm so glad that so many of us still come back to these videos xD this one I especially like due to how Dave puts flat earth through an academic lense to see if ot holds any ground (it doesn't, but I enjoy education surrounding an idea lol)

Theory: some flat earthers don’t actually believe in flat earth. They just want someone to “prove” it to them by giving them a free ride to space.

Petition to send all Flat Earthers on journey to find end of the Earth. *Not waterfalls

As I watch this, I’m impressed with Dave’s knowledge and ability. I also can’t believe we’re having this discussion. And just think, when the day comes when average folks can save up and take a ride into space, all this will go away.

In the UK we see the North Star. In Australia, they see the Southern Cross. You can never, see both, in the UK or Australia. Any questions, Flat Earthers? Good.
