LC

No, that’s not a problem, it’s exactly what FE predicts and what the data confirms. On FE, the local horizontal plane is the same flat plane everywhere. The tangent plane at the observers location is perfectly parallel to the tangent plane at the Pikes Peak summit 31.5 miles away. That’s not an assumption, it’s the definition of a flat plane. So when one calculates the predicted slope from observer to peak = 2° 31' (pure rise/run, no drop) Then move the Stellarium observer to the peak and measure the elevation to the exact same star at the exact same time = 2° 33', the two lines join perfectly into one straight line through all three points (observer → peak → star). You’re the one smuggling in globe assumptions ("the horizontals aren’t parallel"). On Flat Earth they are parallel, and the measured 2° 33' matches the prediction almost exactly (only 2 arcminutes off). The data shows no drop across the 31.5 miles. That’s the entire point of the Celestial Theodolite. If you want to claim the horizontals aren’t parallel, you first have to prove the Earth is curved. You can’t use curvature to disprove the observation that shows no curvature🫡™️
