Nothing

I would be called a theorist, I do not spend time in mathematical problems or equations. I research papers on quantum particles to understand the basics of particle physics which is something you could do. All particles produce an oscillation, a wave length. Drop a ball in a pond of water and it produces waves outwardly. Nothing would have a particle field that would produce an oscillation, a wavelength. Force particles can have zero mass and their symmetry has to be different. It would be a very weak interaction.
