   Chinese Scientists Model Future War in Lunar Space

   A study by Chinese scientists from Xi'an Polytechnical University and Northwestern Polytechnical University explores potential future warfare scenarios in cis-lunar space. The research suggests that spacecraft could hide in complex lunar gravitational zones, pursue and evade each other, and control strategic routes. This could impact modern warfare, which increasingly relies on space-based technology.
