See The Curvature of The Earth (FISHEYE VS NO FISHEYE LENS)

This video is for educational purposes only. In this video recorded at the International Space Station we can see the Earth from an altitude of aproximatelly 400 km or 248 miles. Helium balloons can reach an altitude around 30 km or 90,000 feet before exploding. A common Flat Earth argument is the use of fisheye lenses in the recording of the Earth from space, which creates strong visual distortion. At this altitude, over 10 times higher than a helium balloon can reach, a regular camera lens can capture the curvature. You can also see the ISS as seen from Earth, captured with a telescope by an amateur astronomer in this video:
