Dimensions of Particles

[Tumbleweed]

Maybe it's the Flatlanders or the second dimension (area, plane) that is non existent. Since it is assumed that the universe came from a singularity that inflated and gave us space (and time), perhaps the inflation was multi directional simultaneously, such that volume was created without the process of being an area or plane first. Point goes straight to volume, no second dimension needed. And the velocity, or inherent motion of the inflation, gave us time and relativity

It is strange. For me, even a point has some kind of width. If it existed with no dimensions, how can it exist for real in something which is encompassed as a dimension?

Mathematically, a point has no width, and that is what makes it a point.

Physically, once more, I think your requirement that they have extent is still based on experience of macroscopic objects. Asking how something can "exist for real" under any circumstances, is a philosophical question which will never be answered.
