@peterdrake This reminds me actually of an idea ive played with in my head before. I dont think it has any real possibility in reality. But still cool to think about: Neutron lasers. While lasers arent really possible for bosons in any practical sense that I know of the idea of a focused long distance neutron beam, particularly if its energy level were adjustable to match the material targeting, would be a pretty decent explanation for sci fi beam weapons.
If you havent connected the dots it would cause whatever it is shot at to become increasingly heavy with neutrons and become unstable and if the beam was intense enough would basically just cause whatever it is pointed at to become a nuclear bomb that would explode as the neutrons accumulate int eh material.
