Original review summary

NASA’s calculation was a theoretical model, not confirmation that the dam had measurably changed Earth’s rotation. The model estimated that filling the reservoir would make days slightly longer by about 0.06 microseconds and shift the rotational pole by roughly 2 centimeters—the opposite of the claim that days became shorter.[S1]
