Crossing the Kármán line has major ramifications for which aspect of global governance?
Answer
International law defining airspace versus outer space
The significance of establishing a clear boundary like the Kármán line is most evident in its impact on international law. Without a clear, agreed-upon demarcation, determining the precise legal jurisdiction between sovereign national airspace (governed by aviation law) and outer space (governed by space treaties) would be impossible. This clarity is necessary for discussing national sovereignty and establishing standardized parameters for space exploration treaties, ensuring predictable operational domains for ascending vehicles.
