A Water Level Measures Level Water! Is There Anything Which Can be Used to Detect Curved Water?

Please define “level” as used above.

equilibrium of a fluid marked by a horizontal surface of even altitude

Yes we do. And most scientists can't tell you what is.

Do you mean to say, most scientists can't tell you IT what is, it being gravity?

Well, first of all, I think that is a false statement. Perhaps we should call it the law of universal gravitation.

Then again, scientists cannot fully accurately explain anything.

Yes we do. And most scientists can't tell you what is.

And let's talk about that atmosphere. If space is real and what they tell us it is, its a vacuum.

Here's the problem with that.

Its the 2nd law of thermodynamics.

The laws of physics, specifically the second law of Thermodynamics, states that the vacuum of space should spontaneously equalize the pressure of earth’s atmosphere and increase entropy. This means that our atmosphere should be sucked into the vacuum of space if space is real. But its not. When gravity is used to explain this it fails. Scientists claim that gravity pulls the air molecules back to Earth. This seems reasonable, until your four year old let's go of his balloon.

Just because scientists can't explain to your satisfaction what gravity is doesn't mean they don't know. Gravity adequately explains the pressure differential related to distance from the Earth's centre.

Or, instead of complaining that (your understanding of) physics doesn't explain real-world phenomena, how about offering testable alternative hypotheses.

You do understand that your definition works perfectly well on a hypothetical flat earth as well as on the real near-spherical Earth?

Mind you, given that altitude is the vertical distance from mean sea level, you're basically employing circular reasoning.

And yet, you nor anyone else has actually addressed the OP's question. I personally would have phrased it differently, but the point has been made. Standing water is always level.

No, it is not. It depends on the scale that you are measuring. Have you ever seen the tide? Where does the water go at low tide? Even a small body of water is subject to tidal influence. It's just that we cannot detect it with our own eyes.

It's called "atmos-sphere", not atmosflat. Gravity is real. Jump off a cliff if you are not sure. If a balloon is filled with helium, it will be lighter than air so it will rise because it has buoyancy. Ships float and planes fly because there are principles that overcome gravity. Use a parachute as you jump off a cliff and you will be ok.

The effect of gravity reduces as the height of the air increases. So the air is less dense. Pilots know this. So do aircraft designers. Air produces friction, so supersonic aircraft tend to fly at extreme heights.

This is why reentry is a problem for space craft. They need to fly at extreme velocity to escape earth's gravity. When they come back at the same speed (of course, there is nothing in space to slow them down), they are super heated by the friction of the air. Hence satellites will burn up in the atmos-sphere.

Everything I've said is common knowledge. Unfortunately, there is not nearly enough common sense to go with knowledge.

Yes, pardon the typo. And thank you. Scientists will tell you what they are paid to say. Up is up. Down is down. Zero gravitational forces required.

May the farce be with you. Live long and prosper. To infinity and beyond.

I have eternal life and I will soon be in heaven with Jesus. That's good enough for me.
