Secondly, water. It seems fact that water always find level. But my friend proposed the question,"level to what?". The presumed curvature of the earth relative to its presumed radius? My presumtion is that level is a straight line. Exactly straight. And that's where I went looking for a way to prove whether water finds straight level, or whether it follows the curvature of the earth. Pretty hard to prove on my kitchen table. I'm looking for an experiment. Any suggestions?
I will only try to answer a small part.
Firstly, because gravitation is such a tiny force it is extremely difficult to give any convincing benchtop demonstration. You are always competing with the enormously larger earth. Because of this limitation all the "experiment" demonstrates is that the surface of water need not be straight. It does not attempt to simulate how water can stick to a globe. With that proviso:
Yes, water always finds its own level.
But there is simply no physical law that says that level is a straight line. It is easy to make water deviate from a straight line.
One way is to put it into tank and spin the tank smoothly, as in this video " class="bbc_link" target="_blank" rel="noopener noreferrer">Centrifugal Force on Rotating Water Container.
Of course you will say that the water in that tank is not only subject to the downward acceleration of gravity (or whatever you choose to call it), but to an additional "centrifugal acceleration" due the roation. EXACTLY! The nett acceleration is not in a single direction anymore and the surface aligns itself at right angles to this nett acceleration at each location, as illustrated below:
Rotating Water Curving
Now, please understand that the only reason I am showing this it to demonstrate that the surface of water need not be "straight". It simply depends on the local acceleration, here gravity (down) and centrifugal acceleration (outwards). So, at the outside edge the surface of the water is at about 45° to the horizontal.
I am not suggesting that the rotation of the earth holds the oceans in place, it most certainly does not.
On the globe the nett acceleration is just the local acceleration due to gravity and is directed (almost[1]) towards the centre of the earth as in this rather rough illustration:
Water Curves on Globe
In this case the surface of the water is always at right angles to the direction we call "down", in other words it is "level" or "horizontal", so the water still "finds its own level" alright, but that level is not a perfectly straight line. Though on a local scale it is so close to a straight like as to not matter.
Over a distance of one mile the surface of perfectly still water would deviate only a total of 2 inches from level (±1" if you like) as in:
Water nearly Flat on Globe
So, water finds its own level, but over a large distance that level is determined by the local gravity.
[1] Almost towards the centre because the centripetal acceleration caused by the rotation of the earth causes a slight deviation.

I want you to post a REAL LIVE DEPICTION of replicating this pictured phenomena...an actual man-made demonstration of this in existence...With that depiction, an actual honest explanation of how it was done...
A clear container...holding curved water...man made...replicate it...come on...
When you do, I will have no further need of posting here...
To me, that picture you posted is as ridiculous as bendy light...Which can be bent by the way...in numerous ways...
Thanks.
Sure. Water droplets form spheres. Fluids under equal force from all sides form spheres. In the case of water droplets, that force is surface tension, but for the earth, that force is gravity. The state of being rounded by gravity is called hydrostatic equilibrium, and it's one of the requirements of being a planet, which the earth fulfills.
Fucking short bus, uh hayseed???
Did you read the post?
Okay, for sssslllloooowwww rrrreeeeaaaaddddeeeerrrrssss, in bullet form, the task at hand...
1. Cast or carve a globe;
2. Make the oceans to scale length, breadth, and depth;
3. Include only the largest lakes on each continent and make them to scale both breadth and depth;
4. Include only the longest rivers on each continent and make them to scale length, breadth, and depth;
5. While everything is dry (no H2O added yet)drill a hole through the globe, accurately reflecting supposed axial tilt;
6. Mount the globe on a dowel or whatever allows the globe to spin at scale speed;
7. Applying any known force available to man, add chemically correct water to the surface of the globe. The only thing that can be outside of the globe is an atmosphere identical to the composition of the one found on earth.
I want to see that picture...I want to touch it...
If you can't present that, then I think you should refrain from replying further...
Of course, you knew what I was asking for all along and decided to be a smart ass anyway...
And of course I know what I am asking for cannot be provided and therefore negates ALL SCIENCE relative to RE as all conditions of RE cannot be replicated and are therefore FALSE!
Nothing experimental on your side...just a bunch of BULLSHIT!!!
