Non Matter Particles
Name: Quek Boon K.
Does non-matter have particles? Thank you for taking the time to reply.
I am not sure what you mean by "non-matter" particles. But if you mean a particle that has no mass,
the answer is yes. The simplest example is light which under some circumstances behaves like a
particle (called a photon). It has momentum, but not mass. How and why that is requires explanation
beyond what can be given in a short question/answer forum such as this. The
"simple" answer is that light can "kick" other particles (especially electrons) around, but has
neither mass nor electrical charge.
