A few Questions about the rules
Applicability of Objects
1. Can the object occur naturally or are humans the only viable source?
2. Are objects allowed to change between initial definition and hurting someone e.g. does a particle decaying mean the particle caused the harm despite the fact the particle has decayed?
3. How indirect can the harm caused by an object be, for example, a stray electron could change a value on a computer which could cause harm dependant on the value changed
4. is simple accelerating anything to near the speed of light turning it into a weapon, or would the accelerator be considered the weapon?
5. Inversely would a weapon without ammo be allowed ammo unless specified otherwise?
Object availability (can't and couldn't)
6. What about something like the voyager spacecraft. if an object is manmade and heading away from humanity or remote enough in location is it a weapon with the assumption that we can retrieve it for the sake of using it to harm anybody?
7. what about something that was man made but no longer exists, is it remade for the test? What about if the particles that where originally part of it have changed from fission or fusion?
Other
8. Is the question whether it can be used as a weapon or cause harm?
9. What degree of harm is required. would an alpha particle ionising a single atom count as harm? Does the method have to have a guarantee that it could cause damage? or does the chance that it theoretically could cause damage enough? e.g. if a small amount of radiation could cause cancer but likely wouldn't. would it still count?
