You Can’t Weaponize Celestial Bodies
The same Outer Space Treaty wisely decided to cover humans’ second favorite thing to do after colonization: blowing up other humans they disagree with. So, bad news for anyone hoping for a supervillain-style future where a country has the ability to activate their moon laser to vaporize their enemies, because the U.N. was way ahead of you. Immediately after laying out the guidelines saying that no one is allowed to claim ownership of celestial bodies, they also lay out what I kind of wish they’d called the “Death Star Provision,” which reads: “States shall not place nuclear weapons or other weapons of mass destruction in orbit or on celestial bodies or station them in outer space in any other manner.”
And then probably immediately thinking better of the specific wording here and a government’s deep capacity for shrugging their way through loopholes, added the much wider statement: “The moon and other celestial bodies shall be used exclusively for peaceful purposes.”
Which would also, in theory, make a plan to use some sort of tractor beam to smash the moon into earth and destroy all human life as we know it expressly frowned upon by the U.N.
