What is the flat-earth model, in one paragraph?

A level plane of land and water, a sun and moon that circle above it rather than orbit around it, and a firmament or dome overhead. Distance is measured by observation of the horizon and by the behaviour of water, which finds its level and does not curve around a ball.

Can I test any of this myself?

Yes. Long-distance sightings across still water, the rate at which objects disappear below the horizon, the altitude of the sun at solar noon from two places at once, and the way a level or a laser line behaves over kilometres are all repeatable with ordinary equipment. Our Try It Yourself page lists them with the gear each one needs.

What do mainstream geodetic and astronomical sources say?

They describe an oblate spheroid with a radius near 6,371 km, curvature of about 8 cm per kilometre squared, and gravity directed toward the centre of mass. We link the specific sources for each claim so a reader can check both readings and decide.

Observations · Old maps · Repeatable tests

The ground under your feet has never been measured to curve.

Every claim on this site comes back to something a person can watch with their own eyes: the horizon cutting a ship in half, water lying dead level in a canal, a sun that never changes apparent size as it crosses the sky. We collect those observations, the historical texts that describe a level earth and a firmament, and the experiments you can run yourself — and we show the mainstream reading of each one next to ours.

The files

Where to go first

Twelve files, in the order most people work through them. Each one states what is observed, what the flat-earth reading is, and what the globe reading is — with sources for both.

Observation

What the horizon does

Why a ship disappears hull-first, and what a level sightline over 4.5 km of water shows.

Observation

Water finds its level

Canals, long aqueducts and the surveying that assumes still water is a plane.

Observation

Sun and moon overhead

Apparent size, the seasons, the analemma, and why a circling sun is a live reading.

Source work

The firmament in the old texts

What the Hebrew, Greek and early English cosmologies actually describe.

Source work

Maps drawn level

Azimuthal equidistant projections, the Gleason map, and why the flight paths look the way they do.

Observation

Two skies, one ceiling

Northern and southern star rotations, the absence of a measurable parallax, and the pole problem.

Do it yourself

Tests you can repeat

Six experiments with ordinary tools: level, laser, camera, aircraft, two observers, one stopwatch.

Common questions

A short FAQ

Is this a scientific finding?

No. This site presents a belief-based reading of the observations. The mainstream geodetic account is linked beside every claim so you can check both. What we ask of a reader is only that they look at the observation itself.

What is the single strongest observation in favour of a level earth?

Water. It finds its level, it is used as the reference for every canal and aqueduct ever surveyed, and long still-water sightlines do not show the dip the globe model predicts. Everything else on this site is a refinement of that one point.

Doesn't gravity prove a ball?

Gravity is a model that predicts downward motion; density and buoyancy describe the same motion without needing a centre to fall toward. The objection is taken seriously on Objections, answered.

Where do I start if I have thirty minutes?

Read What the horizon does, then take the laser or level out to a long stretch of still water and run the test on Try it yourself. Your own eyes settle it faster than any page.

Field notes

Observation log

Short entries from the archive. Each records conditions, equipment and what was seen — the raw material the longer files are built from.

Entry 14 · still water, 4.5 km

A Nikon P900 at 83× from a jetty 2.2 m above the waterline: the opposite shoreline reads at the same apparent level as at 1 km, with no measurable drop and no hidden lower storeys. Air temperature and humidity recorded; refraction acknowledged as a factor and argued in the full entry.

Entry 09 · solar noon, two cities

Shadow lengths taken at the same moment 600 km apart, with the sun's altitude difference logged. Both readings, and both models' predicted values, are tabulated on the page.
