Part 3/9:
Much like a suspension bridge, any rotating habitat faces significant strain from its own gravitational pull. To maintain a semblance of Earth-like gravity, calculations dictate that a Ringworld encompassing an average distance from a star—approximately one Astronomical Unit (AU)—would need to spin at extraordinary velocities, on the order of 1200 kilometers per second. Such speeds would have dire implications for impact safety, as even small debris could unleash catastrophic damage.
