DIY Experiments

Find an Accurate 3D Ball Model of Earth if you can:
Sites like Google Earth and NASA show a ball Earth that is inaccurate and 2 x 180 degree turns don't bring the ball back to its original position, unlike any other ball. Challenge yourself to find or make an accurate 3D model of the ball Earth. Ponder deeply on why Google and NASA didn't give an accurate ball Earth model yet. The globe toys don't claim to be accurate and are not used for serious to scale research but you may even start with the toy globes for practice.

As an example, the below screenshots taken using official Google Earth site and NASA app show all or almost all land in complete darkness or complete light, i.e. a case where theoretical science bluff goes completely against verifiable evidences and actual observation and practical experiments.

Moon parallel sighting:
Plan with 2 or more persons in different countries to take picture of the moon at the same time or do a live video conference call and record it with timestamps. Some of them must be in area where there is night and some in area where there is day.
Check any good site on live moon and sun location tracker to plan a good time. A site I checked is Day and Night World Map (Note Antarctica covering the entire South in this Map).
Check alleged globe ball 3D model and test the globe yourself.
Moon should not be visible on day and night side of the alleged globe at the same time.

If you can afford, buy a temperature tester:
Measure temperature under a full or near full moon directly and then measure the same under a shade and note the difference. Directly under moonlight, it is colder than under shade. Just for completion also measure the temperature under direct sunlight and under shade. Temperature under direct sunlight is hotter than under shade. See Moon Temperature test related videos on The Science Bluff - Contradictions between Theoretical Science and Verifiable Science.

Test Day and Night Live Data using Day and Night World Map, which claims to show day and night on Earth and the positions of the Sun (subsolar point) and the Moon (sublunar point) at the current moment.

To test flat Earth simulation, download and use the app named Flat Earth by OProjects on Android or Flat Earth Pro by Othman Alzahrani on Apple and compare it to Day and Night Live Data.

To test ball Earth simulations use, NASA's Earth 3D Ball Model and Google Earth Ball Model and align them with center point of the ball at the location where Sun is shown in Day and Night World Map

Below are sample screenshots taken on a specific time on 16th September 2024. You can repeat the experiment any time and day yourself.

Can you direct your face towards a particular place from all other locations of a ball?
