The response to this open question is as follows.
The claims made by the author rely on a comparison of the events that took place on Easter Island to those in other regions of the globe that experienced similar outcomes.
There is virtually no historical evidence to reference before drawing such conclusions. What occurred on Easter Island, known to the natives as RAPA NUI, remains largely enigmatic. While there are tales and oral traditions that hint at events, none provide scientifically verifiable evidence. The speculative theories range from the idea of the Lemurian continent sinking, prompting many natives to depart and navigate to various parts of the world like Hawaii, the Polynesian islands, and indeed, Easter Island.
By applying Kepler's third law of planetary motion, we understand that the square of the orbital period corresponds to the cube of the semi-major axis. Given that Earth orbits at 1 AU with a 1-year period, we can establish the ratio:
P^2 / r^3= 1
(P)^2 = 4^3
<span>P = 4^(3/2) = 8 years </span>
