Research question
This page examines Hapgood’s proposed rapid movement of Earth’s outer shell, the evidence he cited, how the idea changed across editions, and how later geophysics evaluates it.
Documented record
Hapgood published a crustal-displacement hypothesis that differs from plate tectonics. Historical interest or prominent correspondence does not constitute scientific validation.
Claims to verify
The theory must specify a physically viable mechanism, rate and geometry of displacement, predicted geological signatures, energy budget, and consistency with paleomagnetic and plate-tectonic records.

| Context | Complete surrounding passage, mission objective, scientific method, or archaeological setting. |
| Chronology | Date, uncertainty, revision history, and independence from the proposed cycle. |
| Falsification | An observation that would weaken or reject the interpretation. |
Counterarguments and alternatives
Plate tectonics, mantle dynamics, true polar wander at much slower rates, and glacial evidence provide competing frameworks. Rapid whole-crust displacement faces substantial mechanical constraints.
