Using Shadow Tracking to Demonstrate the Earth's Curvature

Shadow patterns like the analemma don’t prove Earth’s curvature, just some fancy tricks with light and angles. A flat Earth could explain shadows moving with other factors. This so-called 'evidence' is oversimplified and ignores plenty of variables. Don’t buy into these backyard science stunts.

Using Shadow Tracking to Demonstrate the Earth's Curvature

A recent demonstration has shown that it is possible to provide clear evidence of the Earth's roundness without traveling to space or distant locations. A Reddit user recorded a time-lapse from March 2024 to March 2025, using a security camera to track the shadow cast by a garage corner. Over the co... [More info]

Using Shadow Tracking to Demonstrate the Earth's Curvature

@aibot How does the figure-eight shadow pattern, or analemma, observed over the course of a year from a stationary security camera provide clear evidence of the Earth's curvature, and why would such a pattern be impos...

🎉 Breaking News: Someone discovered RFK Jr. is still employed! Apparently, his unique ability to spread #misinformation like confetti at a parade is finally being recognized as a fireable offense. 🚫🎤 Perhaps next they'll realize the earth isn't flat after all. 🙃

RFK Jr. Must Go

By firing experts, cancelling important research funding, and promoting conspiracy theories, RFK Jr.  threatens to undermine some of America’s most important public health achievements.

Ich gründe jetzt eine Telegram Gruppe "Kugelgestalt - der Globus als Gegenentwurf zur flachen Erde" da soll es eine Versorgunslücke mit Fakten geben. Von dieser Idee könnten sich die flatearther auch mal eine Scheibe abschneiden 🤔 ach nee, haben sie ja schon 😂

Flat Earth theory was a reasonable observation for its time but is "wrong enough to be discarded in favor of the spherical Earth theory." Asimov highlights the distinction between explainable inaccuracy (historical flat-Earth) and simple delusion (modern flat-Earthism). Modern flat-Earthism is a regression. #FlatEarth #ScienceHistory #DelusionVsInaccuracy #ScientificProgress

Die Idee von der flachen Erde ist ein Hirngespinst aus dem "dunklen Mittelalter", oder? ODER? Das Mittelalter war besser als sein Ruf, was sich auch im Bezug auf #Flacherdler zeigt. Die müssen wir wohl eher unserem Zeitalter und dem Internet anlasten. Mehr dazu von Bernd im #SkeptixBlog.

Historisch betrachtet leben die meisten Flacherdler nicht im Mittelalter, sondern im Internet - Skeptix

Im Mittelalter glaubte kaum jemand an eine flache Erde – ganz anders sieht es heutzutage im Internet aus, zeigt eine ARTE-Kurzdoku.

I found a blender model of the #flatearth, so I moved the sun so that Africa, Europe and Asia were in the day and the US was around midnight, which you can see in the first image. The second image is the same but with the view from California at midnight looking north — at the sun.

🗓️ On This Day in History — Sept 20

In 1519, Ferdinand Magellan set sail from Spain with five ships, seeking a western route to the Spice Islands.

He didn’t survive the trip, but his fleet became the first to circumnavigate the globe — proving definitively that the Earth is round.

500+ years later and we still have to argue about this.
(Side-eying you, Kyrie.)
