There are countless weapons in the novel Three-Body Problem that left a deep impression on people. The second one that left a deep impression on people was Sophon. In order of appearance, the first one to be mentioned was the Nano Flying Blade.
A sophon is a super-intelligent computing device formed by etching circuits on the two-dimensional expansion plane of a proton after two-dimensional expansion of the proton. It is a three-body weapon in the past that has the characteristics of both extremely high threat and extremely low harm. Its threat is mainly reflected in the fact that sophons can interfere with the results of high-energy accelerators by replacing target particles, thus locking the scientific and technological development of earth civilization, especially basic physics research, making it almost impossible to move forward even half a step.
Its low harm is mainly reflected in the fact that sophons only have the mass of one proton anyway, so sophons have almost no impact on the macroscopic world. Not to mention killing people, even killing a bacterium is difficult. Therefore, the following content is just the result of the author's imagination. It belongs entirely to the field of fantasy. There will inevitably be errors. Please forgive me.
