Expanding earth
The Expanding Earth hypothesis has never been fully defeated on empirical grounds — it was politically displaced by plate tectonics, which itself required decades of resistance before acceptance. Key researchers including Samuel Warren Carey, László Egyed, and Ott Christoph Hilgenberg produced geometric and geological evidence that subduction zones cannot fully account for new oceanic crust generation. The absence of a confirmed expansion mechanism does not equal disproof — plate tectonics also lacked a confirmed convection mechanism at the time of its own adoption. The geodetic '0.2 mm/year' constraint addresses current expansion, not the deep-time geological record.
Evidence
- Samuel Warren Carey, the Australian geologist and one of the most rigorous proponents, demonstrated in his work spanning the 1950s through 1980s that fitting the continental shelves — not just coastlines — onto a smaller Earth produces near-perfect geometric matches with no subduction required.
- Ott Christoph Hilgenberg produced physical globe models in the 1930s showing all continents tessellating on a globe approximately 55–60% of current diameter.
- The mechanism question is contested differently in suppressed-physics circles.
- The Wikipedia-sourced geodetic measurement — confirming no expansion to within 0.2 mm/year — addresses present-day rates and says nothing about episodic or deep-time growth phases that Carey and Egyed's models actually invoke.
- László Egyed, the Hungarian geophysicist, calculated from paleontological data on shallow-sea coverage that Earth's radius has increased at roughly 0.5 mm per year over geological time, a rate below current geodetic detection thresholds.
