Perhaps the entity is not a member of the standard model.
Alone this point source, spinless, dimensionless, massless etc. entity is nothing, but it resides on the edge of existence… with the addition of another such entity, we have dimension, spin, polarity. With the addition of an infinitum of such we have mass, as an extrinsic property a result of the gravitational field. I have even found that configurations of these entities can produce electromagnetism, my apologies however… I am currently working on schematic demonstrations of this. I have developed a system of measurement units that can be used until a connection can be made between these configurations and the members of the standard model.
