Hey flat Earthers, it’s time to put your theory to bed once and for all! “There are so many proofs that the Earth is round, it’s difficult to know where to start. And it’s not okay to think that the Earth is flat; this is not a viable argument,” says NASA astronomer Michelle Thaller.Thaller explains three observable proofs that instantly debunk flat-Earth theory with irrefutable evidence of the Earth’s round, curvaceous, gloriously spherical shape.The ancient Greeks figured out we were living on a sphere over 2,000 years ago, and there are things you can do to prove that the Earth is indeed round—just go to a body of water and look at ships or boats on the horizon with binoculars. Watch the video for the details!You can follow Michelle Thaller on Twitter at @mlthaller.

MICHELLE THALLER:
Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory’s (JPL) Spitzer Space Telescope. After a hugely successful mission, she moved on to NASA’s Goddard Space Flight Center (GSFC), in the Washington D.C. area. In her off-hours often puts on about 30lbs of Elizabethan garb and performs intricate Renaissance dances. For more information, visit

TRANSCRIPT:
MICHELLE THALLER: So, Oscar, you asked the question, “What are some of the easiest ways that you can prove that the Earth is round?” Because apparently, this is something that we’re debating—I have no idea why.
That’s a hard thing for me to even start talking about because there are so many proofs that the Earth is round, it’s difficult to know where to start. And it’s not okay to think that the Earth is flat. This is not a viable argument.
I have friends who have been on the International Space Station, they have orbited the Earth once every 90 minutes; I’ve had personal experience with people who have been up in space and can see with their own eyes that the Earth is round. And of course, we’ve taken all of these amazing pictures from space; they’re so beautiful, all those pictures of the Earth.
So I don’t really know what’s going on right now with this ‘Earth is flat’ thing, but I will tell you that this is one of the things I really enjoyed teaching my own astronomy class about because there are proofs all around you. It is not difficult to know that the Earth is round. In fact, people have known of this for way more than 2,000 years. The ancient Greeks actually had a number of really elegant, wonderful proofs that the earth was a sphere.
So let’s start from the simple to the slightly more complicated. One of the things you can see yourself, with a pair of binoculars, is if you actually go out to a lake and there are boats on that lake, the farther away a boat is the more the bottom of the boat will disappear, and you’ll basically just see the mast of the boat. And as a boat goes farther and farther away the last thing you will see is the very top of the mast of that boat, and that’s because the boat is actually going over the horizon that’s curved—and that means that as it goes farther and farther away you see less and less of the bottom of it, and more of the top of that. You can see that with binoculars by an ocean, by a lake, it’s really easy. That wouldn’t happen if the Earth were flat—you would simply see the boat getting smaller and smaller and smaller as it went farther away, but you’d be able to see the whole thing with the same proportions.
Now, another way that you can tell that we’re on a sphere is to think about how there’s something called the tropics on the Earth, and the tropics are places near the equator of the earth were sometimes the sun is overhead in the sky. This was actually something that the Greeks used, not only to prove that the Earth was round about 2000 years ago, but they actually measured the circumference of the Earth, accurate to within just a couple percent. 2,000 years ago we’ve known that the Earth was round.
There was a really brilliant Greek scientist called Eratosthenes, and Eratosthenes noticed that there was a town called Syene, and on a certain date the sun would actually shine straight down to the bottom of a well. That mea…

Just a little bit of advice for people on here regarding the troll currently using the name 'Towering Genius', though that name frequently changes due to bans and insecurity.
Please do not respond to him. That is precisely what he wants, as you may have noticed, there is an air of desperation around his posts, this is because the only people that will communicate with him are people online who don't know his history. Real life people don't bother any more, he's a waste of their time, and he's a waste of yours too.
Treat him with the contempt he deserves, and ignore him, or post around him, not only will it make your life more peaceful, it will make him furious, there be a spate of about 30 posts a day as he desperately tries to get people to pay attention to him, and then he will give up and try to find a different video to troll, he cannot communicate like normal people, so don't try to.
Don't think for one moment he is a flat earther, he isn't, he's just a lonely man who destroyed his own life and spews out his bitterness on the Internet in the hope of getting attention. It's not rare, and the solution is to realise how pointless he is and ignore him.
That's all I'm going to say on the subject.

Globers cannot hold a high moral ground.
Science lies everyday. Science has been lying everyday since the scientists faked the stick of Eratosthenes from 300BC.

NASA's @mildyconcusseddave1830 is unhinged.
Who else in NASA is unhinged?
There is no evidence of Eratosthenes or his Greek stick. Clealy, NASA is unhinged from top to bottom.

Charles Darwin was the human equivalent of a system crash—no school, no job, no prospects. He lived where society parks its inconvenient truths. Incest? Check. His cousin Galton tried to breed out people like Charles Darwin, but forgot to start at home. And that stutter? Evolution’s punchline. 🤦🤦🤦♂
Charles Darwin exhibited chronic educational failure, lifelong unemployment, and was housed in a psychiatric facility on the city’s outskirts. He engaged in incestuous behavior. His cousin, Galton, was a prominent figure in the eugenics movement. Charles Darwin's speech was marked by a severe stutter. 🤦🤦🤦♂

We have to question evolution:
If Europeans evolved to become a better fit to become Americans then why are Europeans still here?
If europeans didn't need to evolve then it means evolution has stopped! 🛑🫸🫷
Europeans prove that evolution is faked.
Cases:
eastern Europeans
western Europeans
Europe: it's not even a continent.
It is a FAKE continent!

Bizarre evolution: 😨
13.6 billion years ago:
-13.6B years: trillions of light years away, "nothing" blew up! 😂
Between -13.6B and -4B years: nothing happened! Globe fakers created imaginary electrons and atoms. 😂
Between -4B and circa 1800AD: Evolutionists filled this time line with FICTIONAL stories!😂
Between circa 1800AD and 2025:
Mankind burst on our flat earth
Prostitution started.
Telephone was invented.
Internet was made.
Undersea cables were laid.
Globe was faked.
AI appeared.
Evolutionists made more bizarre stories.
Apes turned into humans in their fiction. 😂
They faked evidence using cartoons, molecular fossils, videos, CGI, hand drawings, etc. 😮😮😮

The US is totally broke!😮😮😮 Bankrupt! It owes $36 trillion in debt!
NASA cannot get paid! 😭
NASA has little money to defend its fake 🤥 globe 🌍. 20% of its fakers are shown the door.
NASA brought it upon itself by lying since 1948, taking trillions of dollars for running psyops. 🎯🎯🎯
Michelle Thaler, a communication specialist, is running a psyop. She is not doing any science! She is uneducated in science.
Eratosthenes didn't even exist. His stick is a lie. They faked the existence of stick from 300BC.
NASA wouldn't zoom using p900 which makes the ships re appear after they have presumably gone down below the curvature on the other side of the fake 🤥 globe! 😂😂😂
NASA faked the moon landings!
NASA faked space walks in its swimming pools.
Newton was not struck by any apple 🍎 on his head. Apples didn't even exist in his country at that time.
NASA faked the sucktion of the space.

Prostitution started about 200 years ago circa 1800.
Your Darwin didn't know or do any science. He SPECULATED and then confessed all his lies on his death bed 🛏 when he had no need for money 💰 💰 💰 he made from his lies.
Science is full of lies.
Cases: PILTDOWN MAN fossil, DNA, radio metric dating, atom ⚛, dinosaurs 🦖🦕🦖, and more.

It is UNPRODUCTIVE to argue with globers.
REASON: THEY are not EDUCATED in anything that is somehow related with FAKE GLOBE 🌏EARTH.
SHORT LIST :
Cosmic star paths
Cosmic Sun and Moon paths
Earth's gravity
Earth's rotation
Space
Vacuum of space that does not suck
Trillions of heavy balls stuck between fake gravity and fake suction
Earth's curvature
666
North Pole 💈, South Pole 💈
Magnetism
Map making
Time zones
Theodolite
Antarctica
Arctica
Gps, glosnass, military communication
Line of sight communication, radars,
NEW ADDITIONS:
SUBMARINE sonar pings: reflections
Optical zooming
PS
Globers always show us animations, CGI, simulations, Hollywood painitngs, blue 🔵/ green 🟢screens.
They always make excuses such as NASA's dog ate the evidence. 🐕

From the WHITE HOUSE:
Presidential Actions
PREVENTING WOKE AI IN THE FEDERAL GOVERNMENT
Excerpts:
One of the most pervasive and destructive of these ideologies is so-called “diversity, equity, and inclusion” (DEI).
In the AI context, DEI includes the suppression or distortion of factual information about race or sex; manipulation of racial or sexual representation in model outputs; incorporation of concepts like critical race theory, transgenderism, unconscious bias, intersectionality, and systemic racism; and discrimination on the basis of race or sex.
DEI displaces the commitment to truth in favor of preferred outcomes and, as recent history illustrates, poses an existential threat to reliable AI.
READ THE WORDS: DEI poses an existential threat.

HOW MANY imaginative ways do these globers IMAGINE EVIDENCE in their fake globe 🌍 based universe ?
• Cartoons as scientific evidence !
• C.G.I. globe as scientific evidence !
• Hand drawing of globe as scientific evidence !
• Hollywood movies using hand-painted globe
• Imaginary stick of Eratosthenes as scientific evidence !
• Imaginary evidence of Galileo as scientific evidence !
• Imaginary ancient Greeks as scientific evidence !
• They collaborated with NASA and came up with trillions of FAKE SPACE GLOBES 🌍🌍🌍.
