Location Predictions
v1.1
Generate sunrise, sunset, solar-noon, and celestial-pole predictions from latitude, longitude, and date.
Seasons Simulator
v1.0
Compare the same date at two latitudes to show opposite seasonal daylight patterns on a globe.
Moon Phase Comparator
v1.1
Compare how the same Moon phase and landmark pattern rotate for different Earth observers at the same UTC moment.
Gravity Direction Visualizer
v1.0
Compare two real locations and calculate how much their local down directions diverge on a globe versus a flat plane.
Map Distortion Comparison
v2.0
Measure how the flat-earth disc stretches east-west distances at southern latitudes.
Star Visibility and Latitude
v1.0
Test how star altitude, circumpolar visibility, and hemisphere-dependent sky access change with latitude.
Sun Path Comparator
v1.2
Compare a standard globe Sun path with a simplified nearby-sun flat-earth dome model and test how their daily predictions diverge at the same latitude and date.
Sunspot Observer
v1.0
Render one real NOAA sunspot-region snapshot for different observers and compare how the same solar pattern rotates with latitude, longitude, and UTC time.
Earth Rotation Speed and Centrifugal g-force
v1.0
Calculate surface spin speed and centrifugal acceleration at any latitude.
Circumpolar Star Check
v1.4
Test whether a star rises, sets, or stays above the horizon from a given latitude.
Debunks
Claim-by-claim responses tied to the same topic and underlying theory.
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.
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.
Compass Bearings Do Not Prove A Flat Earth
v1.1
A compass points north on a flat map, so that must mean the Earth is a plane centered on the north pole.
Flat-Earth Map Distortion Does Not Matter
v1.0
Any map has distortion, so the distortion problems in the flat-earth map are not a real objection.
Down Is The Same Everywhere
v1.0
People everywhere stand upright the same way, so there cannot be a globe with different local vertical directions.
Experiments
Repeatable observations you can use to test the same topic directly.
Space Observation Calendar
v1.1
Do month-ahead astronomy calendars predict real sky events correctly when they are filtered for your location, local time, and hemisphere?
