- Documented · A modern flat-Earth revival spread widely online in the 2010s through videos and conferences.
- Documented · Contemporary flat-Earth conventions gather attendees who publicly reject the globe model and share alternative Earth-shape claims.
- Documented · Global Navigation Satellite Systems provide positioning services used worldwide under globe-based orbital models.
- Documented · Late-twentieth-century Flat Earth Society newsletters sustained organized member communication and advocacy for years.
- Documented · Modern flat-Earth messaging has been circulated through online videos as well as in-person conferences.
- Documented · Modern geodetic reference systems model Earth as an oblate spheroid or equivalent ellipsoid for surveying and navigation.
- Documented · Modern researchers and documentarians have examined flat-Earth communities as cases of belief, identity, media practice, and rationality rather than only as geometry disputes.
- Documented · Nineteenth-century experimental demonstrations, including work associated with the Bedford Level, remain reference points in later flat-Earth advocacy.
- Documented · Nineteenth-century flat-Earth advocacy circulated under the label of zetetic astronomy, presenting itself as observation-first inquiry against institutional globe teaching.
- Documented · Nineteenth-century flat-Earth advocacy, including Bedford Level experiments, is part of the longer public dispute history.
- Documented · Online investigation communities have published recreations and critiques of historic Bedford Level-style curvature tests.
- Documented · Popular historical accounts treat Rowbotham’s canal work as a foundational episode later cited by flat-Earth organizers and societies.
- Documented · Public debate over Earth's shape includes organized modern flat-Earth advocacy that rejects globe-based institutional descriptions.
- Documented · Samuel Rowbotham used sighting tests along the Old Bedford River to argue that a long stretch of standing water shows no measurable curvature.
Official3
- Official · Globe-based orbital models underpin the design and operation of widely used satellite positioning services.
- Official · National oceanographic, geodetic, and geological agencies present Earth as an approximately spherical body in operational science products.
- Official · Scientific and mapping agencies publish Earth-shape reference frameworks used for surveying, charting, and navigation.
Contested3
- Contested · A public Victorian wager repeated Bedford Level-style canal observations and produced lasting disagreement over whether the results showed curvature.
- Contested · Competing flat-Earth and spherical-Earth accounts form a disputed public narrative rather than a single settled popular description.
- Contested · Flat-Earth advocates frequently challenge the authenticity or interpretation of imagery and mission data released by space agencies.
