The scale change of Einstein’s equivalence principle

The Gulliver effect is a vertical size change implicit in the equivalence principle. Unlike FitzGerald contraction, it can be both positive and negative. Moreover, it is reciprocal—while one party appears expanded to the other, the other appears contracted to the former: needle formation implies pancake formation and vice versa. Computer simulations are encouraged. The connection to general relativity is not yet fully understood.
