Physics is nowhere near experimenting with such things. Metaphysics has a rather interesting belief that electrons are the smallest 3d particles and look like inflow sinks, positrons are correspondingly outflow sinks, and the flow is made of much smaller 4d particles, that are, upon closer inspection, appear to be similarly made of combining tiny inflows and outflows of 5d particles and so on.
