Is our planet truly flat, or is that just a modern myth refusing to die?

ANSWER — False. The Earth is an oblate spheroid (roughly spherical), not flat. This has been scientific consensus for over 2,000 years, confirmed by ancient observations, modern satellite imagery, and space missions.[1][2][3]

EVIDENCE — NASA (March 11, 2025) explains ancient Greeks used star motions and Sun shadows to prove sphericity; Magellan's crew circumnavigated without falling off an "edge"; space photos since the 1960s show a round Earth.[1] Wikipedia (accessed 2026) notes Aristotle's empirical evidence ~330 BC; flat Earth is "scientifically disproven."[2] NOAA (June 16, 2024) states Earth is an irregularly shaped ellipsoid due to rotation and gravity.[3] Britannica (accessed 2026) confirms empirical observations disproved flat Earth; modern revival is via social media despite evidence.[4] Space.com (April 4, 2025) lists proofs like ship hulls vanishing over horizon, lunar eclipses, and high-altitude photos.[5] No credible 2026 sources support flat Earth; it's labeled pseudoscience and conspiracy.[6]

CREDIBILITY — 10/10. Overwhelming, repeatable evidence from multiple independent sources (NASA, ESA, amateurs) with no valid counter-evidence.

BIAS — CENTER. Sources are scientific institutions (NASA, NOAA), encyclopedias (Wikipedia, Britannica), and fact-checkers (Reuters, Full Fact).[7][8]
