- 0xEF 1y agoIt's my understanding that the Karman Line the conventionally accepted "edge" where you leave the atmosphere and enter outer space, but many call this out as a fairly arbitrary point, arguing that there is no measurable boundary. Useful as a point of reference for positioning, though. Neal possibly just used it as a marker but chose to not define it for this reason.

Kármán said that it's about this height where the aerodynamic lift and inertia being dominant are reversed. https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line
