Spherical vs Circular(planar) wormholes; possibility?
I know that 'they' are theoretical and hypothetical, but please justify deep down to your understanding and I'll try to grab-up as much
Origin of Problem:
Thanks to the fantasy and fiction, there are different types and shapes of wormholes, that can (or may) exist. Shape of given wormhole as seen on either of its faces varies from being a circle to sphere, or some higher dynamic geometry.
In some wormholes (in literature or cinema), transfer of "Living-Being or Material or Energy" takes place instantaneously; while for others that transfer takes considerable time. (i.e.: In some wormholes, things just appear on the other side as they go-through, while in other wormholes, they technically work like a super-slingshot, things are traveling at great velocities.)
Conflict: Circular vs Spherical wormholes
For Circular wormhole, assuming its existence. I can say that it will be a PLANE. Not the surface, but plane, from where the traveling and/or teleportation-things happen. Thus, in theory, it acts like a HOLE to a different space-time and there is nothing physical in that region- no physical matter from the wormhole to be felt, that's why its called as worm-hole. 302
But for spherical wormhole to exist, matter can't be there inside, otherwise it will be a physical thing (like a black-hole or star, say) that lies there in space. And it can't be a whole sphere because that'll add-up to DIMENSION being different on the other side.
It just doesn't seem possible to me, because assuming that a spherical wormhole does exists, and something enters it (interacts with it, to be more accurate), to go on the other space-time. When and where is it going to interact with the wormhole? Is it some spherical plane or some imaginary volume? The working of spherical wormhole confuses me or is not clear to me. Help!
So the conflict boils down to these questions:
(Please try to consider spherical wormhole different from any black hole; if possible)
1. Is it really possible for a wormhole to be Spherical? If possible then, justification of spherical wormhole's existence?
2. What exists in spherical wormhole, under the spherical plane? (I've only encountered resources describing- tunnels through space-time, none with the concept of sphere though.)
If I've missed or deviated from some relevant points please feel free to correct me, as this is my first question here. In advance, Thanking you! :) 43
