That's a bomb which GENERATES a singularity particle or even some particles. I'm not sure anyone had made something like that but anyway...Here's the ID
Actually, it says on the wiki that super high velocity prot makes singularity, so really everybody knows, but nice i guess.
Actually, velocity is what allows PROT to create SING. If you have a PROT laser, and you fire protons down a path lined with ACEL, if they reach a high enough velocity, and then collide with another PROT, then they will make SING. The gravity generated by your bomb only acts as the accelerator for the protons.
