Water, like every other liquid, is LEVEL when undisturbed - over ANY distance. It NEVER curves downward.

Our world is NOT a globe.

It never was. Our limited powers of perception and distant, natural visual illusions were used against us to convince us all that we are rotating at 1000 MPH in one direction, orbiting the sun in a path that is 23.4 degrees off of our rotation at 66,600 MPH, chasing the sun at 90 degrees off of our orbital path at 448,000 MPH, while SIMULTANEOUSLY screaming around the "great attractor" with everything else in the "milky way" galaxy at over ONE MILLION miles per hour!

ARE you kidding me?? FOUR different speeds in FOUR different directions AT THE SAME TIME???

I don't believe it and neither should you.
Research "Rigid Body Rotation With Translation" to discover how a body IN MOTION could never have another body orbiting it. That modern physics explanation DESTROYS any notion that the Heliocentric "universe" (with all its absurd speeds) exists at all!

Research the "Escape Velocity" of rockets.
IF rockets ESCAPE the gravitational pull of the "planet" Earth, then HOW in the world do they KEEP UP WITH our orbital speed around the sun?? They SHOULD be IMMEDIATELY left behind the moment they break free, left millions of miles behind with no possibility of ever catching up. Stranded forever in "space".

"Gravity" doesn't exist and "space" doesn't exist, either.

The known characteristics of density and buoyancy account for EVERY mythical effect of "gravity", and "space" is merely the long-distance ILLUSION of infinite depth created by the differing SIZES of the objects (stars, wandering stars/"planets", nebulae, galaxies, etc.) that are IN the thickness of the Firmament over our heads.

These "lights in the ceiling" are NOT millions of miles away, and the Inverse Square Law of Light PROVES that fact. Become familiar with that law, too. Find out how light, EVERY kind of light, dims fairly rapidly over relatively short distances.

The "speed of light" number we've all been taught - 186,000 miles per second - is AN EXTRAPOLATION. Light, no matter how bright it is at the source CANNOT travel 186,000 miles. It's literally impossible.

We've been lied to and misled about almost EVERYTHING when it comes to the shape and size of our world.

If that bothers you - which it might - research flat earth and the Firmament. Comb through the MOUNTAIN of data that shows our world is level (over ANY distance of water), stationary (even Einstein couldn't locate an optical experiment that PROVES our world moves at all!) and enclosed (look up US military Operations Dominic, Fishbowl and Starfish Prime - all weapons testing missions designed to BREAK through the Firmament).

Watch a hundred or so "flat earth" videos on this channel of mine.
My channel isn't monetized and it never will be, so there's no incentive for me to share all of this with you other than to provide you with a RESOURCE you can use to investigate all this further. Thanks for reading this far.

Enjoy your research.

You don't live on a spinning ball.
