Wormhole residue

[Residue]

Here's my question. If a hole is supposedly taking something out of an area yet wormholes appear in space where it is supposedly a vacuum and thus void of material, how can a wormhole exist Is there some theory I'm unaware of?

I'll guess that a blackhole is critical density
and that a wormhole is zero density

and
Based on a 4th dimension explanation I read:
1D Pete doesn't like nothing
like 2D Fred doesn't like lines
and 3D us prefer something built rather than on paper

Just because there is no matter (read: particles, clumps of things, stars, etc) in a particular region of space doesn't mean that space itself isn't there to be bent and warped. A wormhole is a path through spacetime itself, not something in spacetime.

Gotcha. Thanks.
