is it too much to think that every particle is actaully a point singularity?
i think that if string theory is correct than this assumption could be correct because string theory argues that strings can become a small blackhole and vise versa so therefore i assume that they share the same propeties therefore singularity is one of them.

i found in google that in electromagnetic theory particles are assumed to be singularities but i assume they refer to mathematical singularity nd not physical.

here's what i found (you should know that i havent read thoroughly):

loop quantum gravity,

If we look at three inverse square laws of physics; Newton's universal law of gravitation, Coulomb's law of electrostatic and Ampere's law of magnetostatic, as the distance approaches zero into a point, the force becomes infinite.

Yet to compute the gravitational force of a sphere of uniform mass density distribution, the force originates from a singularity as if all the masses is at a point.

Both mathematician and physicist do want to compute accurately but the experimental data refuse to cooperate.

No uniform mass density can be found in nature except the vacuum (mass is zero?). The electron is a point particle. Together with its antiparticle, the positron, their mass is equal. Yet they possess a magnetic dipole moment, which indicates internal charge distribution. So they can't really be a point particle in the physical sense. Experiment just cannot detect this extended property of point particles. Even the neutrinos do possess a very small amount of magnetic dipole moment.

Science don't yet have the answer why experiments can detect the magnetic moment but not the extension of the point.

No uniform frame of velocity can be found except light's frame (speed is constant in vacuum).
