Eclipses are actually more proof FOR flat earth than against it. A solar eclipse shadow is too small for the measurements we've been told. Plus, how does a penumbra eclipse is when, as you said, the earth is supposed to be between the sun and moon, but we can literally see both the sun and moon at the same time from the same spot?

the sun never changes in angular size at any point which is not possible on a flat earth

I'm not sure what you mean by this. If you're in a dry environment, it certainly does get smaller as it sets. In moisture rich environments, it stands to reason the sun will get larger as the moisture that settles closer to sea level acts like a magnifying glass.

No flat earth model can make single prediction about when eclipses will happen

Says who?

No accurate map has ever been presented for the flat earth.

Actually, until relatively recent times, all explorers used the flat earth map. The Gleasons flat earth map from 1892 was deemed "scientifically and practically correct ; as "it is."

I could go into how flawed the globe model works when heading "due east" or "due west", but it's difficult to explain without visuals.

You can't see polaris from the Southern hemisphere.

True. Almost like they are smaller and localized, and the view has a limited line of sight.... flat earth? Here's a great video on the southern stars on a flat earth. https://youtu.be/kWsvHOyHMc8

Everything on the planet experiences the exact same acceleration of 9.8m² regardless of it's mass or density

But why does there always appear to be a gravitational field of 9.8 N/kg 9.8 m/s². Why those exact measurements?

Is it the earth's mass displacing space and time sucking things towards it?

Or is it something else? A magnetic attraction like molecular magnetism? A natural order of separation with buoyancy and density within certain ranges?

So, in an effort to explain this, experiments like this one demonstrate, at least in part, why Einstein invents the theory of relativity. (See also Michelson–Morley experiment)

The Michelson–Morley experiments said that we should be able to detect the earth rotation's effect on light rays. Turns out we can't. So, Einstein made a theory with bunch of nonsense to explain it away.

But, turns out the theory of relativity still doesn’t explain why gravity doesn't work on subatomic particles. They do whatever the hell they want it seems... and everything is made of them, even you!

So, we invent quantum physics and a theoretical (made up) particle called the graviton.

We still can't find that particle despite our best efforts, so now we invent a new explanation called quantum entanglement.

Entanglement is the unusual behavior of elementary particles where they become linked so that when something happens to one, something happens to the other; no matter what the distance.

Essentially, a particle that is entangled and shares the same effects is in another place, even across the "universe", and is unaffected by gravity in that place, so the particle here with us is unaffected as well. Or.. perhaps they are in both states at once. It's confusing, maybe purposefully so.

So, it turns out mainstream science HAS NO REAL EXPLANATION FOR GRAVITY.

Believe It or Not, Science Still Can't Explain Gravity. They can explain the effect, but not the cause.

I ask you, is it really that unreasonable to believe that, perhaps, objects are simply attracted to areas in which their density/buoyancy is within range of their own? It seems a lot more likely than inventing theory upon theory and theoretical particle upon theoretical particle.

Here's a very detailed video about the subject. https://www.youtube.com/watch?v=RLcgsG1XEic&list=WL&index=3

We have an atmospheric pressure gradient starting at 14.7 psi at sea level eventually reaching nearly zero and a pressure gradient is impossible on a closed system.

Why would a pressure gradient be impossible on a CLOSED system? (flat earth) Seems it would be impossible on an OPEN system. (round earth) You can't have pressure without a container. The round earth has no container and is against the alleged vacuum of space.

The Cavendish experiment proved mass attracts mass.

Yes... and?

The discovery of neptune was made using newtonian formulas

Can you send me more info on this?

All observable celestial bodies are round

By that logic: My lightbulbs are round... so my floor must be too!
