Moonlight and the Cooling Effect Myth

Featured Video Play Icon

Flat-Earthers claim that moonlight is cold and cools down objects exposed to it. It is merely a myth from the 19th-century flat-Earthers, reinforced by confirmation bias in various so-called “experiments” performed by today’s flat-Earthers.

Flat-Earthers experimented and insisted that moonlight has a cooling effect because they failed to control other factors affecting the experiment and maybe even deliberately introduced them to influence the results. They also did not account for measurement errors —the variation between several measurements— and cherry-picked the results that fit their desired outcome while ignoring the rest.

Observing Earth’s Curvature on a Flight

Earth’s curvature is hard to observe from the surface. Even from the altitude of a commercial passenger flight, about 30000-40000 ft, Earth’s curvature is still too small to notice. However, under careful observation, it is not impossible to confirm the curve from the cruising altitude of a jet airliner.

Infrared Vision

When we are unable to see a distant object, then it is due to one of these reasons:

  • Our eyes lack the sufficient angular resolution to recognize the object.
  • Atmospheric condition limits visibility.
  • The object is far enough and obscured by Earth’s curvature.

Some flat-Earthers like to show that a previously unseen distant object can be brought into view using infrared vision. They would take that as ‘evidence’ of the non-existence of Earth’s curvature. They are wrong. Infrared vision can reveal hidden objects caused by visibility limitations, but not ones obscured by Earth’s curvature.
