Flying Over Antarctica: Airliner vs Private Flight

Commercial passenger airliners are similar to public transits. The operator determines the route, and passengers take them if they fulfill their needs. On the other hand, a private flight is similar to a taxi. The passenger determines the origin and destination of the flight.

There is currently no airliner providing a route over Antarctica, and flat-Earthers use it to “prove” that it is impossible to fly over Antarctica. In reality, the airliners simply decide not to provide such routes due to commercial or other reasons. Not because it is impossible to fly over Antarctica. We can take private flights if we really want to fly over to Antarctica, just like we take taxis to go to a location not serviced by public transit.

Lunar Transit Images from DSCOVR-EPIC

DSCOVR is a spacecraft positioned in the Lagrangian point L1 between the Sun and Earth. It carries the EPIC camera that continuously takes images of Earth in 10 wavelengths from 317nm to 780 nm in rotation.

The Moon can appear in EPIC images, and flat-Earthers incorrectly use the color fringing around the Moon to dismiss the images as fake. In reality, the full-color images are composite of three single-color images taken in consecutive exposures in a one-minute span. As a result, the Moon had shifted in the time span and not perfectly aligned in the different exposures, causing the color-fringing after the images are composited together.

Determining the Distance to the Sun from the Transit of Venus

The distance to the Sun was first determined with a good accuracy from worldwide observations of the transit of Venus. A transit of Venus is a phenomenon where Venus passes in front of the Sun. By measuring the time Venus spends crossing in front of the Sun from two or more locations on the surface of the Earth, it is possible to calculate the distance to the Sun.

Flat-Earthers insist that it is impossible to determine the distance to the Sun in the globe model because sun rays are practically parallel. They are wrong. Using simple geometry, the distance to the Sun can be determined from the observations of the transit of Venus.
