# Claim table — i-FER Flat Earth / larger rabbit hole video

- **The Facebook video is an i-FER flat-earth advocacy clip.** — Confirmed: Facebook/yt-dlp metadata identify uploader as i-FER Videos, title “Flat Earth is Just The Beginning of a Much Larger Rabbit Hole,” duration about 815 seconds.
- **The video says flat-Earth advocates hold “empirical, measurable, repeatable science” above theoretical math.** — Confirmed as the video’s claim: Transcript captures this framing; it is a claim about the movement’s self-description, not independent validation.
- **Earth is flat or motionless.** — Unsupported / contradicted by established evidence: Geodesy, satellite navigation, Earth observation, eclipses, circumnavigation, Foucault pendulums, inertial navigation and astronomy all fit an oblate-spheroid rotating Earth model.
- **Long-distance visibility and flat-looking horizons disprove curvature.** — Misleading / incomplete: Atmospheric refraction, observer height, lens distortion, haze/infrared contrast and geometric horizon calculations must be controlled; isolated visuals do not overturn geodesy.
- **Gravity has never been proven; density/buoyancy replaces it.** — False as stated: Buoyancy depends on gravity; density differences explain which way objects move only within a gravitational field. Gravitational measurements and orbital dynamics are foundational across navigation and physics.
- **Antarctica treaty prevents people from finding the edge.** — Unsupported leap: The Antarctic Treaty governs peaceful scientific use and environmental protections; it does not prove an ice-wall boundary or dome.
- **The black-hole image resembles Soundgarden artwork, therefore the science is suspect.** — Pattern-match, not evidence: The thumbnail/video makes an aesthetic comparison. Similar-looking imagery is not evidence that Event Horizon Telescope/LIGO/NASA records are fabricated.
- **The right response is to mock viewers rather than test claims.** — Bad method: Managing Expectations treats the clip as a source lead: identify claims, test them against independent observations, and separate skepticism from evidence.
