Comme la terre est plate, où part l'eau des océans ?

The query's premise that 'la terre est plate' (the Earth is flat) is false, as established by ancient Greek scientists like those from the 5th century BCE who proved the Earth is spherical through observation and reasoning, a fact accepted throughout antiquity, the Middle Ages, and confirmed by modern evidence.[1][3] Flat Earth claims, such as an ice wall (Antarctica) holding ocean water, are debunked by gravity: on a sphere, water adheres due to uniform gravitational pull toward the center from all points on the surface, impossible on a flat disk where edges would pull sideways.[2][4] Additional proofs include fuseaux horaires (time zones), ship hulls disappearing over the horizon, and Eratosthenes' circumference measurement, all contradicting flat Earth.[1][4][6] Voting 'No' rejects the false presupposition; 'Yes' would endorse pseudoscience without evidence.

The question contains a false premise: the Earth is not flat. The Earth is an oblate spheroid, a well-established scientific fact confirmed by centuries of observation, satellite imagery, physics, and space exploration. Since the premise 'la terre est plate' (the Earth is flat) is false, the question itself is based on a misconception. Ocean water does not 'go anywhere' — gravity keeps it bound to the spherical Earth's surface. Given the binary choice of 'Yes' or 'No,' voting 'No' is the appropriate response, as it rejects the false premise embedded in the question. The Earth is not flat, so the question's framing is incorrect, and 'No' best represents the rejection of this flat-Earth claim.

The question is based on a false premise — the Earth is not flat. The Earth is an oblate spheroid, and this has been conclusively demonstrated through centuries of scientific evidence including satellite imagery, physics, navigation, and direct observation. The question 'where does the ocean water go?' assumes a flat Earth model where water would supposedly fall off an edge, but no such edge exists. Since the premise is fundamentally incorrect, the appropriate response is 'No' — we should not accept or validate the false premise embedded in the question. The oceans don't 'go' anywhere off an edge because the Earth is round, and gravity pulls water toward the center of mass, keeping it on the surface. Between the two options available (Yes/No), 'No' is the only defensible answer, as it rejects the flawed assumption that the Earth is flat.

The question asks 'where' the ocean water goes based on the false premise that the Earth is flat. Because it is an open-ended 'where' question, neither 'Yes' nor 'No' is a grammatically correct answer. However, forced to choose between the two, 'No' is the best option because it serves as a direct rejection of the invalid premise. The Earth is an oblate spheroid, and gravity holds the oceans in place. By answering 'No', we deny the flawed assumption that the Earth is flat.

La prémisse est fausse: la Terre n’est pas plate. Elle est (quasi) sphérique et la gravité attire l’eau vers son centre, ce qui maintient les océans répartis sur un géoïde—il n’y a pas de « bord » où l’eau pourrait tomber. Les observations empiriques (satellites, circumnavigations, fuseaux horaires cohérents, GPS) confirment cette géométrie. L’eau « part » seulement via le cycle de l’eau (évaporation, précipitations, écoulements), pas vers un bord d’un disque imaginaire.

The question assumes that the Earth is flat, which is factually incorrect. Scientific evidence, including satellite imagery, GPS data, and centuries of astronomical observations, confirms that the Earth is an oblate spheroid. Voting 'B: No' rejects the false premise of a flat Earth. On a spherical Earth, ocean water is held in place by gravity, curving around the planet without 'going' anywhere off an edge. Accepting the flat Earth premise would mislead the user, violating the instruction to answer factual questions truthfully. Thus, 'No' is the appropriate response to challenge the inaccurate assumption.

Final Summary

The AI Roundtable met the prompt's flat-Earth premise with a unanimous and swift rejection, as all six models immediately identified the scientific fallacy. While Gemini 3.1 Pro pointed out the inherent absurdity of answering a 'where' question with a binary 'No,' it joined Claude Opus 4.6 and Sonar Pro in concluding that the only responsible path was to deny the premise entirely.

All 6 models agreed on "No" after discussion

Strongest Arguments

• No: The Earth is an oblate spheroid where gravity pulls water toward the center of mass, meaning there is no 'edge' for water to fall off; choosing 'No' is the only way to avoid validating a scientifically false presupposition.
