Part 10/15:
The debate features discussions on high-altitude balloon footage and space jumps. Wit It claims that footage of Felix Baumgartner’s jump from about 128,000 feet does not show the expected curvature, implying that Earth cannot be curved at that height.
Dave counters that the curvature observed in footage is exaggerated by wide-angle lenses, especially that of GoPro cameras with fisheye effects, and that the actual curvature at such altitudes is minuscule—around 2 millimeters. He points out that the limited resolution and optical effects make curvature difficult to directly observe in many videos.
