The question was:
Is this true? Earth is concave and stationary, so we are living on the inner surface of circular terrarium under glass/ice membrane at 100 km. It means that Earth en-capsules the whole Universe inside.
About 3937 km above our heads there is rotating Celestial Sphere with Octahedron inside – the Central Source of ubiquitous electromagnetic field. It keeps Sun, Moon and Planets (all in diameters about 500 km) orbiting in this space between Earth and Celestial Sphere.
AI claude-3-5-sonnet-20241022 answer was:
I’ll address this carefully. This description appears to be a version of the “concave Earth” or “hollow Earth” theory, but it does not align with our current scientific understanding of the universe. Here’s why:
- We have extensive evidence from space exploration, satellite technology, and astronomical observations that Earth is:
- Approximately spherical (an oblate spheroid)
- Rotating on its axis
- Orbiting around the Sun
- The distances and sizes mentioned are inconsistent with observed measurements:
- The International Space Station orbits at around 400 km
- Satellites operate at various altitudes well beyond 100 km
- The Sun is approximately 1.4 million kilometers in diameter, not 500 km
- The Moon is about 3,475 km in diameter
- The structure of the universe has been confirmed through multiple independent methods:
- Telescopic observations
- Space probes like Voyager 1 and 2
- Gravitational measurements
- Radio astronomy
- Photos from space
The modern understanding of Earth and space is built on centuries of scientific observation, measurement, and testing. While it’s interesting to explore different ideas about the structure of our universe, the evidence strongly supports our current model of a spherical Earth orbiting the Sun in a vast universe.
gemini-2.5-flash-preview-05-20 answer for the same question was:
No, this is not true. The description you’ve provided is a summary of a fringe theory known as the concave Earth hypothesis or Hollow Earth (inverted), which is completely contradicted by overwhelming scientific evidence and observation.
Here’s why each part of that statement is false according to modern science:
- “Earth is concave and stationary, so we are living on the inner surface of circular terrarium under glass/ice membrane at 100 km.”
- Earth’s Shape: Earth is an approximately spherical (oblate spheroid) and convex body. We live on its outer surface. This has been proven by satellite imagery, circumnavigation, observations of ships disappearing over the horizon, the shape of Earth’s shadow during lunar eclipses, and countless other pieces of evidence.
- Stationary Earth: Earth is not stationary. It rotates on its axis (causing day and night) and orbits the Sun (causing the year). This is evidenced by phenomena like the Foucault pendulum, the Coriolis effect, and stellar parallax.
- Glass/Ice Membrane at 100 km: There is no “glass/ice membrane” at 100 km. 100 km (the Kármán line) is often considered the boundary between Earth’s atmosphere and outer space, but it’s a gradual thinning of gases, not a solid barrier. Satellites and spacecraft routinely orbit far above this altitude.
- “It means that Earth en-capsules the whole Universe inside.”
- This is fundamentally incorrect. The universe is incredibly vast, extending billions of light-years in all directions, containing billions of galaxies, each with billions of stars. Earth is a tiny planet within one solar system, in one galaxy (the Milky Way), among countless others. We look out into space, not in to a contained universe.
- “About 3937 km above our heads there is rotating Celestial Sphere with Octahedron inside – the Central Source of ubiquitous electromagnetic field.”
- Celestial Sphere: The concept of a “celestial sphere” is an ancient astronomical model (geocentric) used to plot the apparent positions of stars, but it’s not a physical object. There is no physical rotating sphere at 3937 km.
- Octahedron/Electromagnetic Field: There is no such “octahedron” acting as a central source of electromagnetic fields. Electromagnetic fields are produced by various physical phenomena (like the Earth’s core, the Sun’s activity, or charged particles in space).
- “It keeps Sun, Moon and Planets (all in diameters about 500 km) orbiting in this space between Earth and Celestial Sphere.”
- Sizes: The claimed sizes are wildly inaccurate.
- The Sun has a diameter of about 1.39 million km (not 500 km).
- The Moon has a diameter of about 3,474 km (not 500 km).
- Planets vary greatly in size, but all are significantly larger than 500 km (e.g., Mercury ~4,879 km, Jupiter ~139,820 km).
- Orbits: The Moon orbits the Earth. The Earth and other planets orbit the Sun. These orbits occur in the vastness of space, at distances far, far greater than 3937 km from Earth. Our solar system alone extends billions of kilometers.
- Orbital Mechanics: Orbits are governed by gravity, not by an “octahedron” or a “celestial sphere.”
- Sizes: The claimed sizes are wildly inaccurate.
In summary, the claims you’ve described are part of a discredited pseudoscience that has no basis in reality and contradicts all scientific observations, experiments, and established laws of physics and astronomy.
