I What Are the Physical Properties of Human-Sized Worm Holes?

TL;DR Summary

Worm Hole Theoretical question. Worm hole physical properties.

Hello Everyone in the forum:
I have a theoretical question about Worm Holes. So for the sake of this question let's just assume we have the technology and the power source to fire up a small human size worm hole. My question would be regarding the edge of the worm hole. Would you be able to touch the edge or would the worm hole be more like a fourth dimensional sphere? (since it is connecting space by folding it on a higher dimension). However, if you were able to actually touch the edge would it be solid or would it be infinitely sharp?

My question would be regarding the edge of the worm hole.

The wormhole doesn't have an edge. It blends continuously into the surrounding spacetime.

Would you be able to touch the edge or would the worm hole be more like a fourth dimensional sphere?

Neither.

since it is connecting space by folding it on a higher dimension

This is a common pop science description, but it has nothing whatever to do with actual mathematical models of wormholes. In the actual mathematical models, spacetime is just a 4-dimensional continuum; it's not embedded in anything higher-dimensional. In spacetimes with wormholes, the continuum is multiply connected, but that can be described entirely in terms of properties within the continuum, without having to make use of any embedding in anything higher dimensional.

However, if you were able to actually touch the edge would it be solid or would it be infinitely sharp?

A wormhole would seem to someone traveling through it like empty space, which has neither of these properties.

Thank you. Can you recommend any books in the subject?

Not books, but the original wormhole paper by Morris & Thorne is worth reading:

Here are some wormhole visualizations from a reputable source (of course, assuming the negative energy needed to stabilize them could be produced - none has been detected in our universe):

Thank you very much for your time. I had the feeling most Hollywood movies had this wrong. I started thinking about this and wasn't able to find a specific answer in most articles I read.
