3d wormhole space matter model - wormhole by Michael Taylor

In physics, a wormhole is a hypothetical topological feature of spacetime that is, fundamentally, a 'shortcut' through space and time. Simply, spacetime is a two-dimensional (2-D) surface that, when 'folded' over, allows the formation of a wormhole bridge. A wormhole has at least two mouths that are connected via a throat or tube. If the wormhole is traversable, then matter can 'travel' from one mouth to the other via the throat.
