what is earth crust resplacement theory????

It is well-known through continental drift and plate tectonics that the earth’s landmasses are not stationary, but form parts of large, independently moving crustal plates. This motion is, however, very slow by human terms, and the 30 degree shift proposed by Hapgood would take millions, if not hundreds of millions, of years to complete according to plate tectonics. In the 1950s, Hapgood developed a theory called Earth Crust Displacement (ECD) which could account the shift, and yet not contradict the theory of continental drift. The basic notion of ECD is that the earth’s lithosphere, although composed of individual plates, can at times move as a whole over the asthenosphere.

To better visualize the ECD, consider a loose-fitting jig-saw puzzle on a table. Normally, if one tries to move the puzzle by applying uneven pressure to the pieces, the puzzle crumbles and pieces slide over each other. This simulates plate tectonics and continental drift. Consider the results, however, when a more even force is applied to the puzzle. By pushing evenly on the bottom edge, it is possible to slide the whole puzzle across the table without disrupting the pieces. This is the heart of ECD.
