Scientific Evidence Rejecting the Hollow Earth Theory

The hollow earth theory has persisted over the years, largely due to the works of certain proponents. Notably, Marshall B. Gardner's book, while questioning some aspects of geology, remains largely unaddressed by the scientific community. His hypothesis has been largely ignored and ridiculed, much like the theory itself. However, scientific evidence overwhelmingly discredits this theory and confirms that the Earth is a solid planet with a liquid core.

Earth's Mass and Gravity

One of the fundamental pieces of evidence against the hollow Earth theory is the consistent measurement of Earth's mass and gravity. These values align perfectly with the properties of a solid planet with a molten core, providing a strong contradiction to any hollow Earth model.

Soundwaves and the Earth's Interior

Soundwaves travel at different speeds through different materials, making them a valuable tool for studying the Earth's interior. If the Earth were hollow, we would observe significant variations in these soundwave speeds. However, acoustic measurements reveal a consistent structure, confirming that the Earth is solid with layers of different properties.

Experiments Probing the Earth's Structure

Experiments have been conducted to probe the large-scale structures of the Earth using vibration techniques. These experiments have consistently failed to detect vast hollow spaces, further supporting the solid planet model. No evidence has been found to support the hollow Earth hypothesis.

Geodetic Evidence and Triangulation Networks

Geodetic measurements such as triangulation networks have been used for centuries to map out the Earth's surface and features. These networks involve measuring the separation between vertical lines at widely separated points. On a flat Earth, these lines would be parallel. On a concave hollow Earth, they would converge. On our actual spherical Earth, they diverge.

Over the past 400 years, millions of these measurements have been taken across nearly all land masses. The results consistently show a divergence of about 30 arc seconds per kilometer of separation, providing definitive proof that the Earth is indeed approximately spherical. This approach serves as a powerful refutation of the hollow Earth theory.

Conclusion

The hollow Earth theory has no basis in reality and is contradicted by multiple lines of evidence. From the consistent measurements of Earth's mass and gravity, to the use of soundwaves to probe the Earth's interior, and finally, to geodetic evidence, every available method of investigation has confirmed that the Earth is a solid, spherical planet with a liquid core. Such thorough scientific evidence makes any support or continuation of the hollow Earth theory both unnecessary and unreasonable.
