Wtf?? Weak gravity??How do you measure gravity?
00x000 (1 day ago)
With a Gravimeter and that's no joke. Earth’s crust has different density in different locations and at different depths. The density of the crust is determined by the type of rocks that make up that area.

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🚽👉🧠

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?

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? :-)
VEGAN WARRIOR (2 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.

.....and again you evade providing credible evidence of a flat earth.

What would you say if you found out my name was on that list? Would you still BELIEVE? LOL Again, blind faith has been the plague of mankind throughout human history.
Matt Swinden (1 month 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 (1 month 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.
Matt Swinden (2 months ago)
VEGAN WARRIOR - "No one has ever or will ever experience curvature of the earth." No sir, that is an incorrect statement as over 550 men and women have gone to space and have seen and experienced the true shape of the earth. Just because YOU have not personally experienced, does not mean it does not exist. Again, I ask you, do you have any proof that is credible and scientifically sound that the earth is flat? Because your statement above has no factual validity.....it is merely your opinion and your opinion is not fact or proof. Thanks to modern day weather satellites that have taken over 1 million images of the globe earth, we have photographic proof of the true shape of the earth - like this image - https://epic.gsfc.nasa.gov/

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........

The drawing is way too drastic. The earth isn't a perfect sphere, but it isn't a deformed meat ball either. Because of it's size it will still look like a sphere, even though measurement wise, it's not technically a sphere

FrenchCrow (5 months ago)
With a gravimeter. In ancient times like 18th century they used a pendulum (the period is related to g).

Is their volume there in this model? Because that would make the sea level rise
Dan Shetler (6 months ago)
Elevation would not have any meaning on a globe because sea level is a defined point on Earth(the surface of the ocean is considered a benchmark) that all elevations are taken from.
Jerome Mariano (6 months ago)
um, water always fills to the shape of it's container and is level
Trinity Slayer (6 months ago)
did I just hear that gravity is stronger on some parts of the earth than others? isn't earth's gravity 9,807m/s²? isn't it constant? what is gravitational constant then? so gravity is relative to where you are on the planet? so what does that entail ? probably dumb questions but I was just freaked by that a bit. I knew this sea level thing would be complicated after watching this video.
FrenchCrow (5 months ago)
g=9.807m/s² is the conventional standard value of gravitational acceleration on Earth. But the actual values of g is not the same all around the world because the Earth is not a perfect sphere and is not homogeneous. G=6.67408 × 10-11 m3 kg-1 s-2 is the gravitational constant, which doesn't change.

If gravity in different areas vary, where would you jump the highest on Earth?
Riddick (6 months ago)
Technically, the equator. However the change in gravitational acceleration would be barely noticeable, and therefore something like this would be impossible to properly test.

Well so the scientists can only measure sea level with an accuracy of a meter. .yet they tell us that the sea level is rising by so many mm a year...that sounds like they dont really know..! like a lot of things like whether its natural global warming or climate change. It all sounds natural to me!
