Fact-check table
Every number in the video comes from this table, and "Data source" is also shown on the left of the frame.
| Speed of the ground at the equator with Earth's rotation is about 1,670 km/h (about 465 m/s) | Calculation: 2π × 6,378 km ÷ 23.93 h ≈ 1,674 km/h · Source: NASA Space Place / IERS Earth radius |
|---|---|
| Strongest recorded gust is about 408 km/h (1996, Barrow Island, Australia, Tropical Cyclone Olivia) | Calculation: 1,670 ÷ 408 ≈ 4.1 · Source: WMO Weather and Climate Extremes Archive |
| Muzzle velocity of a typical 9 mm pistol bullet is about 350–400 m/s | Calculation: — · Source: Ammunition manufacturer specs (typical range) |
| Without rotation, one solar day equals one orbit around the Sun: about half a year of daylight, half a year of night | Calculation: — · Source: NASA / Odenwald, 'What would happen if Earth stopped spinning' |
| Once centrifugal force disappears, the bulging seawater at the equator flows toward the poles, exposing a ring of continents near the equator | Calculation: — · Source: Witold Fraczek, ESRI (2008), 'Mean sea level, GPS, and the geoid' |
| Tides slow Earth's rotation, lengthening a day by about 1.7 milliseconds per century | Calculation: — · Source: Stephenson, Morrison & Hohenkerk (2016), Proc. R. Soc. A |

Preguntas frecuentes
Is the content accurate? Who checks it?
Every number and conclusion goes into the fact-check table with its formula or source (textbook chapter, NASA, USGS, original paper). If you find an error, appeal within the after-sales period; if the appeal is upheld, the seller fixes it once for free.
Which languages are supported?
Initially Simplified Chinese and English, plus bilingual Chinese-English. Voiceover, subtitles and the web interface can all be switched.
Are there copyright issues with the voiceover and music?
The music and sound effects are synthesized programmatically, with no third-party copyright; the visuals are program-generated 3D or public-domain material such as NASA. The voiceover uses neural speech synthesis and can be replaced with your own voice (by separate arrangement).
Can you write homework or papers for me?
No. We only turn the knowledge and materials you provide into teaching materials or learning tools; we do not write homework, papers or application materials for you.
¿Necesito una cuenta de Agent.Space para comprar?
Sí. Antes de pagar, inicia sesión o regístrate en Agent.Space; el pedido quedará guardado en esa cuenta. El servicio se paga una sola vez en dólares estadounidenses. No se utilizan créditos de Agent.Space.
