5.Gravity has never been proven in the first place, therefore cannot be dis-proven. Also you can't prove a negative.
Gravity is measurable:

Newton's law is empirical, we use it because it works when doing calculations involving gravity. If it did not work it would not be used, what more proof do you want? Einstein formulated the laws of relativity
In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.

6. Then please submit them for scrutiny my good sir.
This is a video of a guy taking a telescope and DSLR camera and proving by experiment the curvature of the earth exists. He shows all his workings and all his measurements as well as all his equipment used. He adds a nice explanation of perspective and why most online calculators get it wrong when calculating curvature. They usually do not include humidity, refraction of light or position and exact shape of the earth. In your above table you posted values of curvature of a globe which was generated by CAD (Computer Aided Design). I believe I would get close to those values if I run the actual experiments, but I do not have the money or other resources to do so. (hence the video of the guy who did it).

This video explains in nice, easy illustrations how the earth is tilted and why that fact is why we have seasons. It is also the reason for the sun appearing either below or above the Ecliptic (the line above us on the celestial sphere found if you project the orbit of the sun outwards) depending on the season, date, time and viewers location on the earth.

This is an experiment proving the gravitational acceleration constant and thus that gravity is quantifiable and therefore exists. A grade 10 learner could do this physics in grade 8 with the equations of motion (I am a tutor in physics and mathematics in spare time).

These are a start at least.

7. See the chart I posted earlier.
See my comment about CAD and how they influence calculation by using near perfect spheres on models.

8. Iron loses it magnetic properties when you heat it up, and that is what the THEORY of gravity needs to work.Oops.
The outside layer is liquid this is true, but the inner third of the core is solid because of the pressure difference. There is a slight variance in the field strength because the solid part shifts, this is why there are sometimes weak points in the magnetic field that can cause interference on earthside communication devices and electrical transfer mediums. Solar flares can also physically rip through our magnetic field and damage electronics in a large area and even cause large scale blackouts (this has happened in the past).

Thus it does produce a magnetic field which protects us from the harmful frequencies of charged particles. Some of these particles however do enter through the north and south poles where the magnetic fields act as funnels. This is what causes the Auroras (Borealis for northern lights and Australis for southern lights) this can be found on any astronomy source and I know this because I did a course in basic astronomy before deciding to study the stars and find the answers I have been seeking since I can remember having a critical thought.

9. Here's your experiment Sir. (https://youtu.be/nUFMZkxochs?t=5377)
In this experiment he is trying to show how apparent drift will not happen in a directional gyro when it is standing stationary. I agree completely with this statement seeing as drift only occurs when the gyro is moving away or towards the equator. This effect is compensated for by the technology of GPS and micro controller chips which help laser guided gyroscopes be as accurate as possible. This is why planes tend to crash less and pilots know where to fly with no visual aid, seeing as all the technology on planes and jets do most of the looking for the pilot and just translates the data into information the pilot can use to make informed decisions. Here is another video explaining the concept:
https://www.youtube.com/watch?v=mkdKZQwfiN8

Also look at his reference points from start to finish in his car when using the directional gyro in his car for the driving part. They change during the drive, thus the reading cannot be taken as accurate because we cannot be sure that his car and the gyro is oriented in the exact same direction in which he started his drive.
Start:

Finish:

Now I ask again. Disprove the gravity law of newton and the relativity law of Einstein, show me a picture of the Antarctic wall and possibly what lays beyond, or what do you think lays beyond? Show me where your multiple luminaries come from (the one is from an Indian myth remember), what they look like and which laws govern their movement so that eclipses can be predicted as they are being predicted by the physics and astronomy you so whole heartedly try to discredit. My mathematics and science is solid, the laws work and I have not seen anything that shows or experimentally (accurately) tells me otherwise. I mean gravitational waves were recently detected after studying black holes, they were predicted by Einstein and Hawking’s works.

Im going to have some load shedding now XD lieflike Suid Afrika.😛

DeeJay met his match? lol

@Sidius Everything you said is irrelevant twaddle until you can prove the axial rotation of the earth, the curvature as per the chart, and Gravity. Feel free to post every single video you can find on YouTube that triggers your confirmation bias. I want experiments, not your opinion.

@Sidius Also it is impossible to disprove Flat Earth because mathematically it is impossible to prove a negative. You need to show the evidence FOR your model.

@Sidius At best you'll come up with ten or so, and each and every single one of them is debunked in this video. https://youtu.be/-Ax_YpQsy88

BA mathematical proofs

Beautiful maths

31.7 MILES of curvature drop-off over a short hop of 500 miles is how much curvature there is supposed to be.

But tbh sick of trig rn. Deriving the inverse trig functions is kanker

I don't care for maths. Who's going to argue with AutoCAD? 😉

Nobody

Cause AUTOCAD IS MATHS

And yet they do lol

schooled the flatters

Say what?

idk

Just typing random shit right lol

ah yes ok lol
