But you don't mention "MARSEILLE" city point... I don't know how is it in anglosaxon country... "the tide gauge16 was set up in 1883 at number 174 of the Corniche in Marseille, in Anse Calvo. The goal is to determine an origin of the French altitudes. The measurements were made continuously from January 1st, 1884 to December 31st, 1896, over 13 years. On January 1, 1897, the arithmetic mean of all the measurements made during these thirteen years determined the average sea level at this place. This average level has been adopted as the French reference zero altitude"

ohhhhh shit. I bet the ' flat earchers" had a field day with this video. if I had one wish in the world , it would be for alllll the " flat earchers" to get together in one spot . take a walk, train, plain, boat ride etc, to the end of the earth . it's a win win . if their wrong then hey , they will be a lot smarter ! and if their wrong they hey , they die ! so it would all work out ! 3rd option they win a prize to visit the moon to make sure that's real too and maybe get stuck there until the end of time ! we all win !!!

Cesar Raudales (1 month ago)
Level is a horizontal line or horizontal flat plane according to the Cambridge Dictionary. What about that? Level is a horizontal line use to measure how high above it or how low beneath it an object is. Is not rocket science! But, wait! Because that simple, in correlation with reallity, and easy to understand definition kills the globe model, they need to come up with all this mongo jongo, where they talked to much and explain anything. My dear good God!

Complete bs that makes no sense! Reminds me of “scientists” claiming what is at the center of the earth. Nobody has been there! They have only been 7miles deep!! Lmao! Science no longer uses the scientific method, only formulas and calculations based on theories!
Sebastian Stark (24 days ago)
People haven't been to the sun, so according to the scientific method it doesn't exist!!!!!11 Your logic doesn't make any sense. Also please stop using miles and use the metric system like basically everyone does.

And yes also include; _____earth rotates, spins, tilts , all seven sea has different levels, there is air & space, different temperature, ice melting, seasons_____ consider all these things and then see what is the sea level of your area from google earth or Wikipedia. Earth is a global village and villagers can see anything never mind.

Charles Pemberton (3 months ago)
If you set two large posts at the same height above the sea, one in Australia and one in California, and built a bridge connecting the two, the middle of the bridge would need to be set at the same height above sea level in order for the bridge to be level. Proof that Earth's water always Finds Its level. And proof of Flat Earth.
Art Vandelay007 (3 months ago)
Charles Pemberton // Your conclusion is wrong because your premise is false (and impossible). A bridge of that length with only one support at mid-span would cause that bridge to dip into the water over 99% of its length. The bridge would require support piers at regular intervals underneath it's entire length so no portion would sink into the water. The height of each pier would be dependent on how deep beneath the ocean floor you would need to dig before striking bedrock for a solid footing, plus the mean local sea level at that point, and repeat for all support piers. This method would then account for the curvature of the Earth, as well as for changes in elevation along the sea floor.
You could have used 7 minutes to make this video instead of 3. It's so fast that I have to pause and ponder upon the facts that you state. Anyways, very interesting information.

This is utter bullshit. Please, everyone watching this RESEARCH FLAT EARTH. Earth is NOT a sphere, an oblate spheroid, or anything curved. (There IS a "circle of sight" that surrounds each of us 360 degrees. Don't confuse that with a ball. Do not conflate sphere and circle! ) THERE IS NO CURVE OR SPIN. There is no ball earth, it is just in the human mind. Published science shows NO SPIN. So much so they had to invent relativity in order to hide the NO SPIIN evidence! But don't believe me, of course. Do your own research. Save your sanity. Do you like science? You will love flat earth. Do you hate science and think it is confusing? Well, discover REAL science: RESEARCH FLAT EARTH. It takes some time, and you must put aside your ego for at least a few hours, but it is worth it!
Sebastian Stark (24 days ago)
Maybe don't tell people to do their own research and give us some links to credible so- wait those dont exist

Carolyn Gutman-Dey // I feel very sorry for you and others who believe in this false Satanic Flat Earth doctrine. Someone has sold you a bill of goods, and you have bought into it hook, line, and sinker. Just think about how ridiculous you sound. All of the greatest scientific minds throughout history are wrong, and you are right? You should be ashamed of yourself...

diego lara (6 months ago)
What kind of education is this?🤦‍♂️😒 In no way this video is even close to 1% accurate nor proves any proofs of what he’s talking about. Wake up people, level does not mean curve, nor bent, nor twisted it means STRIGHT. Look up a construction level stick and let that sink in🚽👉🧠
Art Vandelay007 (3 months ago)
diego lara // The air bubble in a carpenter's level can be used to indicate a level condition because liquid is not affected by the curvature of the Earth over such short distances. Large bodies of water such as lakes, seas, and oceans are a different story altogether. The waters are constantly in turmoil, always sloshing about in all directions, always trying to seek level, but they NEVER do. Mean Sea Level (MSL) means just that, it's an "average" of varying sea levels measured at a specific location. "Sea level" exists solely as a baseline or datum from which land elevations (above or below) can be taken.

Wait mass attracts more mass on earth as well? I thought it had to be something much bigger, I thought that tectonic plates move because of conventional currents. Can someone explain?
Sebastian Stark (24 days ago)
Every piece of matter attracts stuff. If you are in a house for example, there is an *extremely* tiny pull from the house onto you which makes you a *tiny* bit lighter. If you take something like tectonic plates, they are large enough to have a noticeable effect.

Thumbs down #733...sorry we see through the masonic lies. The indoctrination has been severed :-). Thanks. P.S. I do have one question...how do they know what's at the center of the earth again? Is that theoretical or fact based on expedition or something? :-)
Sebastian Stark (24 days ago)
It's based upon math and observation of effects it has on things we can see.
VEGAN WARRIOR (7 months ago)
Bullshit! LMAO Center of the earth huh? When has mankind been to the center of the earth to confirm any of this bullshit...never! Water doesn’t take shape of a ball nor does it curve. If you think it does, show me. These ideas are no different than the belief if you throw a virgin in the volcano we will have a great harvest. LMAO The stories have changed but not the lie. People nor objects can stick to a spinning ball LMAO. How ridiculous...Masonic teachings are the worst lol.

Matt Swinden (6 months ago)
VEGAN WARRIOR - Here is a link that lists the men and women that have been to space - https://en.wikipedia.org/wiki/List_of_space_travelers_by_name I see that you evade providing credible evidence of a flat earth. You claim that the photos from NASA are fake. Prove it. You have made the claim, the onus is on you to support that claim. "Again, no one experiences the earth as a globe, " That is because the earth is really huge 25,000 miles in circumference. At 69 miles, there is only 1% curvature. Just how much curve do you think you will see at ground level when you cannot see more than several miles. And yet the curve is demonstrated all time. The simplest is to watch a ship drop below the horizon, first to disappear is the waterline, then the hull, and finally the superstructure. If this was a flat earth, then the ship would never drop below the horizon, but merely stay above it but growing smaller and smaller. The same with a sunrise or sunset. If the earth were flat, then the bottom of the sun would never drop below the horizon. "The moon missions were obviously fake and space travel in no way what it is claimed to be." Prove it. You made the claim, again the onus on you to support the claim. "So if there is a burden of proof required it's on the claims of a globe" It has been proven time and time again. Most recently with over the 1 million images produced by weather satellites from various countries. "where people in Australia are literally upside down while we are literally right side up. " That is a fallacy. In space there is no upside down or right side up. Now explain why is it impossible for water to be on a "spinning ball"? Now keep in mind that the "spinning ball" is slowly rotating once per 23 hours and 56 minutes. Here is a simple experiment, place water on a slowly rotating merry-go-round that is rotating once per day. How much water is spinning off?
VEGAN WARRIOR (6 months ago)
You claim 550 people have been to space and have witnessed the shape of the earth for themselves? Are you sure? If so how, and please provide this so called evidence that has been obviously captured by all these people? You ask me to PROVE the earth is flat. My answer...proof is not required. Why? Because we only experience the earth flat. Again, no one experiences the earth as a globe, oblate spheroid nor a pear all contradictions to the fake photos shown by NASA. The moon missions were obviously fake and space travel in no way what it is claimed to be. So if there is a burden of proof required it's on the claims of a globe...where people in Australia are literally upside down while we are literally right side up. Ridiculous and this mind controlled idea requires pure imagination and blind faith. It goes against reality. Water always finds its level...impossible on a spinning ball. The burden of this lie is on you believers my friend...LOL, not me.

So than if were to flood on a FLAT area of ground, the water would be higher in the middle that the outsides? EG 160km of Bolivia's salt flats, would have 1000 meters in the middle and NO water on the outsides........

Just a question, how can the sea ever be levelled at all if the earth is curved? Doesn't water fill it's container or am I missing something?...

Cause of gravity. Some spots have a tiny bit more gravity and therefor attract a bit more water.
