How does gravity hold the moon in place, while astronauts float/drift in space, much closer to Earth??
A great power which holds massive celestial objects in place, somehow cannot hold s#%#% in space, much closer to Earth, much smaller.....
Gravity curves water around a ball.
A very unique ball, where water forms around it.
The problem is - you cannot show any water which curves around a ball.
It would be noted in all scientific papers, that water can curve around a spherical object, and remain in place.
This phenomenon of water curving around a sphere, bound by a 'gravitational force', is utterly absurd.
Your argument is that water curves around Earth, since gravity makes water curve around Earth.
Nobody can prove water curves around a sphere, first of all..
Gravity doesn't exist. Water doesn't curve around a ball, stuck around it!!

TO ALWAYS FLY AIRCRAFT IN A CONSTANT DESCENT, WHICH IS REQUIRED TO ACCOUNT FOR EARTH'S CURVATURE???????
Luckily, pilots are not total morons like flat-earther seem to be, and they're probably aware that their plane is kept at a level altitude by the Earth's gravity. Gravity is what curves the plane's path over the curvature of earth.

I'm still waiting for anyone to show me where they mention everyone must fly planes in a slightly downward direction at all times, if possible, or at least most of it....
Curvature of Earth, if it existed, would be ESSENTIAL KNOWLEDGE before anyone ever flies a plane, right??
Do they mention curvature, and if so, do they mention how important it is for flying a plane?
Why don't you find out what they teach about flying in Earth's curvature in flight schools?
Go ahead...

Well oceans prove you wrong... so technically anyone can prove that water does curve around a large enough ball...
Just attempt to cross a large body of water... and of course theres other ways... videos of people proving it without trying to... but those are all CGI right?

They don't. Why should they? This displays a basic ignorance of physics - or perhaps a wilful misstatement of facts. All planes have altimeters. All they have to do is stay at the height they have been told to by ground control. Besides, an aircraft flying level at a given altitude and trimmed for level flight will stay at that altitude. That's what they teach at flight school.

Of course, they don't consider any 'curvature' of Earth, as I said.
The planes are commonly flown level, trimmed for level flight, at a given altitude....indeed so.
Not in an arc.
It's all about being in level flight.

I don't think that you understand basic physics. If they are flying at the same altitude for long periods of time then that takes curvature into account. What part of that do you not understand?

You don't understand the point, as yet...
Planes fly level, or mostly so.
Whatever altitude they fly a plane, it is all based on sea level, the point of origin, for all further altitude settings.
Altitude is mostly the same throughout a flight. It does NOT matter what the terrain below is. If the plane is over mountain range, or a deep canyon, or any sort of CURVATURE, it does not change/alter/effect the plane's altitude. Since altitude is based on sea level, and nothing else.
That is why people wonder how a plane would not fly into space, when altitude remains the same - how can Earth's curvature not be an issue?
Because the Earth is not curved. Simple as that.
A plane flies at an altitude based on sea level. Not on what terrain is below the plane. Terrain below changes constantly over a flight, although it doesn't matter, anyway.
So this alone shows there is no curvature on Earth.
And as I mentioned before, the plane is flying level, throughout (or most of) the flight.
It is NOT level to ground below, as I told you earlier on...
It is level within air. Not in descent, or lift.
The Vertical Speed Indicator measures level flight. And if the plane is in descent, or ascent, too.
No curvature is there to measure, or to worry about, you see?
I just go on all of the evidence, on both sides, and follow wherever it leads me.

A plane flies at a certain altitude, throughout most of the flight.
It flies level, as well.
Which means there is no curvature.
To fly over a sphere at the same altitude cannot be flown level. Because it is an ARC.
An arc is not level anywhere. Arcs cannot be flown level.
A plane must fly downward, because the arc is downward.

Average arc of the Earth is around 8 inches......per mile squared.
Less if you increase the radius by flying at 5 miles in altitude.
What is so very important to understand is that planes cannot fly level over 1000 miles, at the same altitude, over a spherical surface, because thousands of feet curvature cannot be accounted for.
You must realize that a spherical surface is, in fact, the complete opposite of a flat surface?
A sphere, no matter how large, is NEVER flat. It cannot be a sphere if it was flat. A ball is round, everywhere.
The instruments prove it is flat.

actually it is "accounted for"...
the earth isn't a flat surface... IF you fly over a mountain your altitude changes dramatically according to the earth
adjustments for the curve of the earth are barely taken into account...
