How Satellites Transform Earth Science

Bob the Science Guy uses astronomy, mission data, geometry and repeatable observations to test what the model predicts. The goal is to connect the claim with evidence that can be checked independently.

$Measure Earth Curvature Across a Lake With an Auto Level A surveyor’s auto level establishes a local horizontal across a 2,552-foot lake, while benchmarks tied to the water surface provide equal-height reference points on both shores. The experiment quantifies instrument precision, operator uncertainty and atmospheric refraction, then compares the observed vertical offset with the curvature predicted for Earth.$
