Horizon Rises to Eye Level
v1.0
The horizon always rises to eye level, so Earth cannot be curved.

Flat-Earth Claim Debunks
Each page tests one flat-earth claim using the same standard: claim, calculation, proof, graphics, and conclusion.

Curvature & Horizon
Earth bulge, line of sight, hidden height, and horizon geometry.
No Curvature Is Visible
v1.1
The Earth cannot be a globe because no visible curvature appears over water or at normal viewing height.
18 debunks
Sky, Moon & Latitude
Sun paths, seasons, stars, Moon orientation, and latitude-driven sky behavior.
A Local Sun Explains Day and Night
v1.5.1
A small nearby Sun moving above a flat plane can explain day and night without a globe.
A Local Moon Explains What We See
v1.1
A small nearby Moon moving over a flat plane can explain Moon phases, lunar orientation, and observations without needing a globe.
We Do Not Feel Earth Moving
v1.0
If Earth rotated and orbited through space, people should feel that motion directly.
Seasons Can Be Explained By A Circling Sun
v1.0
A Sun moving in wider and narrower circles above a flat Earth can explain the seasons without a globe.
Southern Stars Do Not Work On A Globe
v1.0
The southern sky cannot fit a globe model, so reports of southern star motion or a southern celestial pole must be false.
Antarctica Is An Ice Wall
v1.0
Antarctica is not a continent around the south pole. It is an ice wall around the edge of a flat Earth.
Eclipses Do Not Prove A Globe
v1.0
Lunar eclipses do not prove Earth is round because any shape can cast a round shadow somehow.
Time Zones Are Artificial, Not Geometric
v1.0
Time zones are just man-made schedules, so they do not prove a rotating globe.
Sun Rays Prove A Local Sun
v1.0
Crepuscular rays show the Sun is nearby because the rays spread out visually through clouds.
Why Is The Sun Not Lighting Up Space?
v1.0
If the Sun is real and space is real, space should be brightly lit everywhere. Dark space photos prove the Sun is local, fake, or hidden by a dome.
Sunsets Are Only Perspective
v1.0
The Sun does not go below a curved horizon. It only appears to recede into perspective.
Polaris Proves The North Pole Is The Center
v1.0
Because Polaris stays fixed in the north, Earth must be a flat plane centered on the North Pole.
Two Celestial Poles Are Impossible
v1.0
One real sky cannot have both a north and south celestial pole, so globe astronomy must be wrong.
Moon Phases Are Just Earth's Shadow
v1.0
The monthly Moon phases are caused by Earth shadowing the Moon, so the usual Sun-Earth-Moon explanation is unnecessary.
The Moon Is Not A Reflection Of Earth
v2.0
The Moon is a mirror or projection of Earth, its dark patches match our continents and it is not a separate rocky body.
Venus Phases Fit A Flat-Earth Local-Light Story Too
v1.0
Venus phases do not help the globe model because a flat-earth sky could just assign changing light to Venus.
The Firmament Dome Is Not Real
v1.0
Stars, Sun, and Moon are fixed on a nearby glass-like dome or firmament shell that encloses a flat world.
7 debunks
Satellites & GNSS
Orbits, passes, dish geometry, and live positioning signals.
Satellites Are Not Real
v1.0
Satellites are fake, and communication or tracking systems are really just balloons, towers, or fabricated stories.
GNSS Works Without Satellites
v1.5
GPS and GNSS are really just ground towers or fake software, so they do not prove anything about satellites or a globe.
Satellite Dishes Point Too Low To Reach Space
v1.0
Home dishes point too low above the horizon, so they must be aiming at nearby towers instead of satellites.
Satellite Passes Could Just Be Balloons
v1.0
Predicted satellite passes do not prove orbiting objects because balloons could explain moving lights too.
Apollo Moon Landings Were Real
v1.0
Apollo crews never walked on the Moon, the landings were filmed on Earth, often attributed to studio work or Kubrick-style productions.
ISS Footage Shows Real Zero-G
v2.0
Space-station video is filmed in pools, aircraft parabolas, or wire rigs because sustained weightlessness cannot be real.

Gravity & Earth
Effective gravity, rotation effects, and geodesy comparisons.
