Yes! Water levels are super useful tools in construction. Sometimes when I was learning how to hang pipe we were having a devil of a time deciding how to measure certain complicated runs.
Then I remembered learning about water levels from my grandfather as a kid. Problems solved, my supervisors minds blown.
Thanks @ceattlestretch
Water is also a great tool to understand motion. It will always tell you if the container is in motion, no matter how big or small
What about the ocean? I reckon so though..... We have tides and swells, winds and storms which are all due in part to the motion of the earth.
Maybe, I’ve been looking for proof of the supposed spin & curve for quite awhile. Haven’t found any yet

Could the earth be flat after all?
I'm from the arctic Norway, we have midnight sun and the polar star is almost directly above our heads. Now I've moved a bit south and there is no midnight sun and the polar star is clearly on the north of the sky. Such a simple observation is very trivially explained with the round earth theory, and very hard to explain with a flat earth theory.
Much easier to explain on a ball, if the sun is 93,000,000 miles away, if it’s a much closer sun, as it appears to me, a plane explains just fine.
Why doesn’t the North Star ever move if we are moving 67,000mph around a giant fireball moving 483,000mph, in a galaxy moving 1,300,000 mph. Seems highly improbable
Danged ol math 😊
The Polar Star does move indeed.
Moving north & moving slower rotationally is a giant problem. As are rivers on a spinning ball & airplanes..... so many contradictions with a curved spinning ball & reality
As I understand it (I'm no hydrologist mind you) hydrodynamic principles change with huge volume of water. Maybe that could account for different effects of movement?
Sure, but you’d be spinning 1000mph at the equator & significantly slower 1/2 way to the pole. Water behaves universally in my physical life experience. Why does the spin of the earth not affect flight times in any direction? There are many more examples of things that I can model perfectly on a big sea level plane, but need crazy theoretical terms that can’t be modeled to make work on a ball.
It is the most interesting subject I’ve ever studied, & by far the most taboo. If you start trying to have the conversation, you will see some very passionate responses backed by very little logic & giant leaps of programmed faith. Most interesting
I actually spent ten minutes of my life watching this now. That's ten minutes I'll never get back.
The question in the video is ... a plane is travelling from the equator, across the north pole and down on the other side of the planet during 24 hours. In the beginning of the trip, the plane will move with the spin of the planet and have much more speed than what it has over the north pole. What is causing the plane to slow down, and what is causing it to speed up again when going down on the other side? Also, what causes the plane to keep the curvature of the earth, and not fly out into space? Is the pilot constantly actively steering the plane down to follow the curvature and to the left to follow with the earths rotation?
The obvious answers are:
However, the questions "does the pilot actively need to steer to the left and down" seems outright silly from a practical point of view. A blindfolded person walking, steering a boat or (god forbid!) steering an airplane will not be able to steer straight for long, probably it won't take more than some few minutes before the person has done a 360 degree turn. A person or an autopilot navigating a plane or a ship has to constantly counter winds, waves, turbulence and currents - even the rotational direction of the propellor. A 360 degree turn during 24 hours? That's really a negligible adjustment. Same goes with the height and pitch of the airplane, it has to be trimmed and adjusted all the time. A 180 degrees change in pitch during 24 hours is also quite negligible.
"I've been playing pretty much flight simulators" - that's about the funniest "argument by authority" I've seen. :-)
The lack of difference in effect traveling in each direction & at different speeds along the variably rotating globe make it unbelievable to my logic & would require a huge leap of faith on my part to believe it. There are obvious standard answers to these questions, but they are unbelievable to my logic when I actually think about the supposed mega forces involved vs how everything actually calmly & universally works everywhere I’ve been on earth.
I like the video below more than the previous, if you want to see some autocad trig

When I was younger it felt like adults didn't grow older. I simply wasn't able to see it; the faces of my mother and my grandparents was after all the same every day, thus it was hard to accept that they hadn't always been like that, and that they eventually would grow older.
The same can be said about the effects of the spinning earth, they are there, but they are too small to be felt - and as said also quite negligible compared to the other forces acting on the airplane. If the earth would have been spinning very fast, then yes - the effect would have been more pronounced, but the earth is not spinning very fast. Yes, the rotation speed of the airplane is big compared to the speed of the airplane, but that doesn't count, it's outside the reference frame. The airspeed - the airplanes speed through the atmosphere - is constant.
Your weight is actually less at the equator than at the pole - the centifugal forces at the equator is 0.03 m/s^2 - not much compared to the gravity at 9.8 m/s^2. Due to the centrifugal forces the earth is also not completely spheric, but a bit squeezed out around equator. This makes a person on equator further away from the center of mass, which again causes the gravity to be less pronounced. This effect is slightly bigger than the centrifugal force. Source
I made a very similar analogy about how heavy drinking affects people recently. From day to day they feel fine compared to the last day, but they can’t accurately compare to a year or five ago.
I actually watched a proof video of that equator centrifugal math just yesterday 😆
The mathematic models & explanations work as models, but seem far removed from my experience. These are truly incredible speeds the earth is supposedly moving at & incredible rate change going north & south but no measurable physical afffect on any part of the earth nor is there any consistent measurable affect on travel despite these huge supposed physical forces.
We have highly developed & accurate senses to detect motion & balance to protect ourselves. We perceive much smaller rate changes in every other possible example. Yet the earth spins so fast it causes a bulge, but we can’t measure it on the ground or see water affected any differently near the equator.
Most interesting
Thanks for your response,
The lunar eclipse is on my list of things I need to examine, seems to be used by both sides of the argument a lot.
As far as the scope is concerned, I’ve spent an equal amount of time examining my own jaded psychology. You need to ask yourself about the truth & representation of the death of jfk, the moon trips, the twin towers & numerous other events. If you believe the main media story on those, probably not gonna get anywhere with a flat earth. However if you see problems with all of those things why would you trust other giant things requiring a leap of faith, that in my view contradict physical experience.
Also the unheard of peace regarding the Antarctica treaty is strange. They also get a lot of important traffic there.
There are alternate explanations for planets & retrograde motions that make more logical sense to me. I’ll find some links for that & a lunar eclipse. Thy are all theoretical models
Would love to see any good 3D modeling
Looking at the sky to measure the Earth is irrelevant: EVERYTHING in modern astronomy about stars are assumptions. The facts are that all large bodies of water are level, the Earth has no measurable curvature and it does not accelerate.
Giant theoretical models that get bigger & longer & farther away all the time, yet are said to be known facts 👍
I do not assume that all of the history that has been taught to me is accurate. Therefore I can not assume that I know exactly what has been known for millenia. Judging by the history I’ve been alive for, things are constantly remixed by the authors.
I also can’t assume I know all possible reasons others have for their actions. Many more possibilities exist than any one mans imagination in my opinion.
Spiritual deception is very common from what I’ve seen, televangelists come to mind, psychics, tarot cards, palm reading, pedophile churches.
But the basic physics that we experience are a better argument than vague broad topics.
Does the spin of the earth affect airplanes?
