Interactive models, calculators, and simulations connected to “Sun”.

Day and Night Model

v2.0

Estimate daylight duration by latitude and date, then compare with observations.

Astronomy Sun Projection

Crepuscular Ray Perspective Comparator

v1.6.1

Compare parallel sunlight, anticrepuscular convergence, and a nearby-lamp contrast to explain fan-shaped sky rays with perspective geometry.

Perspective Sun Optics

Eclipse Geometry Visualizer

v2.0

Show how Sun-Moon angular size and Earth's umbra geometry fit one coherent eclipse model.

Eclipses Moon Sun

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.

Astronomy Sun Observation

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.

Sun Sunspots Observation

Eratosthenes Earth Size Calculator

v1.0

Measure real Sun elevation at two locations on the same UTC instant, then derive zenith-angle difference, meridional arc, and Earth circumference.

Shadows Sun Geodesy

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.

Astronomy Latitude

Sun Rays Prove A Local Sun

v1.0

Crepuscular rays show the Sun is nearby because the rays spread out visually through clouds.

Astronomy Projection Latitude

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.

Experiments

Repeatable observations you can use to test the same topic directly.

Sunspot Orientation Comparison

v1.0

At the same UTC moment, does the same sunspot pattern rotate with observer location the way globe-Earth viewing geometry predicts?
