Perspective Compression: a Perspective Aid to Determine If a Curvature Exists

Soundly’s pictures and videos of Lake Pontchartrain power lines and causeway really stirred up flat-Earthers’ nests. They clearly show the curvature of the Earth, where it is usually hard to discern. For the rest of us, those pictures are simply the consequence of the fact that the Earth is a globe.

But obviously, flat-Earthers can’t take this, and they invented various excuses to attack the credibility of these pictures and videos. Some of them look for specific vantage point where it is impossible or very hard to discern the curvature.  They would conclude if the curvature can’t be seen from these viewpoints, then it should not be visible from Soundly’s viewpoints.

Perspective: Not the Reason a Sunset Occurs

One of the major holes in the flat-Earth model is the apparent motion of the Sun. The sun rises and sets once a day. But if the Earth is flat, then sunrises and sunsets should never happen, and the Sun would be visible all the time, from anywhere on Earth. In order to plug the hole and  ‘explain’ this problem, they invented an ad-hoc hypothesis that the Sun sets because of perspective.

The pretext is that an object appears closer to the horizon as it is moving away from the observer. They extrapolated this fact and wrongly assume that if it keeps going, then eventually it will appear to go down crossing the horizon line and is no longer visible.

The Size of North America in Pictures of the Earth Taken From Space

How much of Earth we can see at once depends on our distance from the Earth. The closer we are to the surface of the Earth, then the smaller part of the Earth we can see at once. Conversely, the farther we are from the Earth, more of the Earth are visible to us.

The difference in the size of North America in these pictures relative to the size of the Earth is often presented as “evidence” that we have been lied to. In reality, it is simply a perspective effect. The pictures are taken from a different distance from the Earth and with a different camera field of view.

Lake Pontchartrain Power Transmission Lines: Evidence of Earth’s Curvature

Lake Pontchartrain is a lake in Louisiana, United States. There are power transmission lines about 24.27 km (15 mi) across this lake. They are practically straight and each tower is uniform and has the same height, making these towers ideal for observing the curvature of the Earth.

They are first popularized by Soundly who presented evidence of Earth’s curvature using a series of photos and videos of the power lines in June 2017. As of now, the towers and other objects on the lake are probably the most popular Earth curvature tourism spot in the world.
