This argument and Acceptance's argument above it prove my point. It's convex. That's a sphere dude. No matter how many circles you draw there is no point on earth where you hit a wall and the earth stops. And if there was one on the poles, there would also have to be one everywhere else.

It could be convex on one side and then you sail to a flat backside just fine. It could be shaped like a hershey kiss and still give you the effect you are claiming. Our limited perspective is just that, limited. If you can't see it as a whole there is no way of knowing 100 percent and we can't see it as a whole. We take measurements, make observations, and attempt to draw conclusions based around that. That's a fallible method.

I know a guy who got a speeding ticket and sent a picture of the money for the fine in the mail. Somehow that wasn't good enough for the government but somehow that picture is. I can't get onboard.
 
I believe the advancement of the human species allows us to overcome earth's gravity with a rocket and put a camera up in space to take pictures.

How the US, China, Russia and the other 'higher ups' got together to grab money and power away from us simps is beyond me. :dunno:

I'll go with the obvious. :poke:

If I drop my pencil on the floor am I not witnessing gravity?

No, gravity is a model or story about why your pencil falls. You can't see or detect gravity "waves" or force apart from the supposed effects.

Water is curved naturally. It is H2O right? It seeks the lowest point at all times (due to gravity).

These are contradictory, no? When I'm talking about curved water, I'm talking about the water that is allegedly evenly distributed around a sphere. Water doesn't behave like that. It finds it's level, as you note. Theoretically one should be able to accurately measure a still body of water with laser to see if there is indeed a drop.

Gravity can be measured in several different ways. It exists and it is quantifiable

Gravity is also why water can be curved and “level” . Level means equilibrium, and equilibrium means even gravity. “Level” isnt a scientific term, it’s just used commonly.
People prove that when they get derpy and say “the earth isn’t round it’s oblong” or whatever. The oceans can be “misshapen” to keep it “level” between varying gravitational pulls

To another earlier point about sticking to a spinning ball, here are some quick physics:

The acceleration (change in direction and/or speed) required to keep you stuck to the earth when standing at the equator is v^2 / r, where v is the tangential speed of the earth (about 1040 mph or 465 meter/second) and r is the radius of the earth (about 6,378,000 meters). The acceleration you'd feel is only
1727886855218.png

So about .034 meters/second^2. Our measurements of earth's gravity near the surface of the earth puts the acceleration we feel from the earth at about 9.81 m/second^2. It dwarfs the required acceleration to keep us (and water, and everything else) on the earth by about a factor of 300. Or phrased differently, the force you feel from your weight is about 300 times the force required to stick you to the earth (Force = mass * acceleration).

NASA page I pulled the numbers from: https://pwg.gsfc.nasa.gov/stargaze/Srotfram1.htm
"uniform circular motion" is the term to search for if you want another source on the formulas, most college-level intro physics books probably have it, and I'm sure you can find instructions for labs where you measure it too.

Anyhow, already spent too much time typing this up. If I have time I may pop in again. Carry on.

Didn’t you just post the formula for it?

And outside of academia, we see it in real world examples with satellites and such when they use it to “slingshot” their way to the destination. They can do that because the gravity of objects can be calculated, even if we can’t touch them. (This also shows that everything in space is moving, which we can also calculate).

We just saw that with one of the recent moon landing attempts. Mechanical failures caused the lander to take too long to travel and when it got to where it was supposed to go…the moon wasn’t there anymore.

When I'm talking about curved water, I'm talking about the property of water where it naturally finds it's level, which you can see and measure on your own. A curved earth doesn't have flat water anywhere — there is always some degree of curve. Yet I have never seen anyone demonstrate this curve, even with all the sophisticated instruments of measure that we now have, such as lasers and so on. In fact, I have seen people demonstrate the opposite over thousands of feet (Lakes on a still day).

Regarding acceleration, we simply don't ever feel it. Ever. One would think that at least there would be an occasional blip that changes acceleration to the point we could detect it. But that has never happened in recorded history. Regardless, the point is that your own senses tell you that you are on a stationary, non rotation plane — not a spinning ball.

A formula describes the phenomena but it doesn't tell you what it is. There is no way to directly detect gravity.

Below are the formulas and results for calculating curvature of water due to gravity on the surface of the earth that has a radius of 6371 km. You are the one doing the visual observations. Can you offer sufficient valid evidence that there is no curvature of water over the given distances? What is your proof?
