But the current theory of the building of the Great Pyramid — the notion that it was assembled from the inside out, via a spiraling internal ramp — is probably still the best construction plan.

Following that plan, we could replicate the Wonder of the Ancient World for a cool $5 billion.

… While the pyramid was originally built by 4,000 workers over the course of 20 years using strength, sleds and ropes, building the pyramid today using stone-carrying vehicles, cranes and helicopters would probably take 1,500 to 2,000 workers around five years, and it would cost on the order of $5 billion, Houdin said, based on manpower and cost of constructing the Hoover Dam on the Colorado River during the Great Depression. The dam contains a volume of concrete roughly equal to the stone in the pyramid. By comparison, the 1,776-foot-tall One World Trade Center being constructed in downtown Manhattan will cost an estimated $4 billion. …
