# Where can I find an experiment that is repeatable, measurable, testable, and observable that proves the Earths alleged curvature?

Observation of other planets and suns. They are ALL round!

Set up a vertical post, say 10 feet high, on the edge of a lake.

Then 1 mile along the shore of the lake set up another post.

Put a mark on both posts at the height of your eye.

Observe one post from the other (using a telescope or binoculars) and get someone standing at the other post to mark the post at the base of the post as you see it (use a cell phone to indicate where you think the ground is).

Then go to the other post and observe how far the observed "base" of the post is above the actual ground surface.

Put a 3rd post 2 miles from the first one.

The curvature of the earth will be apparent and the height difference between adjacent posts will be the same.

Experiments were asked for, not cartoons or CGI.

alleged? One can't allege a proven fact, one can only allege an assertion unproven. Be that as it may the verifiable proof is legion. Here are but a few: https://www.popsci.com/10-ways-you-can-prove-earth...

200 mile limits are what a country owns  of the water from land

this is because the  tall ship cannot be seen farther than 200 miles   the top of the ship drops below the  horizon

the theory is this

WATER  conforms to a flat surface over a  object

so a flat earth would have  flat water to forever

the  SPHERICAL EARTH  HAS ROUND OR CURVED WATER SURFACE

HARRY IS AN IDIOT
THEY HAD  TELESCOPES   BACK WHEN THEY HAD CASTLES   and  the ship does  DROP BELOW THE WATER LEVEL AND AFTER A WHILE YOU CANT SEE THE LAND FROM THE SHIP TOO ..

harry  you should  grow a brain before you state an idiot idea

Sail a boat out to sea until all evidence of land vanishes, turn around, come back to shore. Film the entire event with a witness and lawyer to notarize authenticity.

Just note, the brain dead flat earthers will go to no limit to call it fake.

Get an airplane that flies high enough, and Bob's your uncle.

But, I'm sure that the view outside the windows is just some sort of government mind control, and you'll just be spreading more mind control in those chemtrails.

Travel to space and visually measure the curvature. Or just use any of the existing photos.

Nobody has been to space and there are no photos just CGI images.
