Rob Skiba’s High-Altitude Balloons

Rob Skiba launched several high-altitude balloons to record the curvature of the Earth, or the lack of it as he hoped. He used a customized GoPro camera to eliminate the inherent barrel distortions in stock GoPros and record a flat horizon instead of a distorted one.
His results show the curvature. But he refused to accept it, and his conclusion said it is flat, without spending any effort to measure it as others did.

Indonesian FE101 Eratosthenes Experiments
​

FE101, a community of flat Earth victims in Indonesia, performed a nationwide large-scale Eratosthenes experiment. Their goal is to measure the distance to the Sun, as well as to determine which one of the flat & sphere model more correctly represent the actual shape of the Earth.
They apparently cannot get a consistent figure for the distance to the Sun. On the other hand, the globe model always yielded the consistent Earth’s circumference, proving the sphere model more accurately describe the Earth.
They refused to accept such reality. Half of their leaders spent a week to manipulate the results by hiding “bad” data. The rest of them tried to find solace with an unscrupulous flat-Earther who calls himself Dr.Zack. Dr.Zack then provided them with just another made-up “explanation” why such result can happen with a flat Earth.

Seismic waves are waves of energy that travel through the Earth’s layers and are a result of earthquakes, volcanic eruptions, massive landslides and large human-made explosions. Some types of seismic waves travel through the interior of the Earth and are detected by seismic stations on the other side of the Earth. By analyzing the types of waves that are received by seismic stations, we can determine the interior of the Earth.

Flat-Earthers are often seen saying that it is impossible to determine the interior of the Earth as nobody has gone there. They are wrong. Using seismology, we can determine the interior of the Earth without going there physically.

There are several types of seismic waves. The types that travel through the interior of the Earth are P-waves (primary) and S-waves (secondary).

P-waves are longitudinal waves (the displacement of the medium is in the same axis as the direction of propagation). These waves travel faster than other waves and can move through any material, including fluids.

S-waves are traverse waves (the displacement of the medium is perpendicular to the direction of propagation). S-waves are slower than P-waves, and cannot penetrate all types of material as easily as P-waves.

When an earthquake happens, it will generate P-waves and S-waves. Depending on the location of a seismic station all over the surface of the Earth, it will detect both types of waves,  only P-waves, or nothing. From the kind of waves that are received by many seismic stations all over the world, we can determine the interior of the Earth.

Flat-Earthers are often seen repeatably stating that the deepest borehole we can drill through the crust of the Earth is only 12 km (8 miles) deep. They would conclude from the fact that it is impossible to determine the interior of the Earth. They are wrong. Using our knowledge of seismology, we can identify what lies inside the interior of the Earth. Just because they are unable to understand seismology, it doesn’t mean seismology is wrong.
