A question about portals from the 'portal' games.
In the games, pairs of flat, identically sized and shaped, effectively for simplicity rectangular, portals, that lay flat on surfaces, link two places.
Light, orientation of objects and momentum are conserved, relative to the orientations of both ends, as if the space going though one is seamlessly attached to the space on the other side of the other.
Something with one end protruding into a portal diagonally for example will also exist with its other end protruding diagonally out of the other portal. In this example there could seem from some angles to be multiple objects, where there is really just one.
I don't know if the portal mechanism is explained in the 'half life'/portal universe as using worm holes, but for the sake of this question, assume we don't know how this is achieved, only how it behaves.
Also there are limitations such as portals being unable to exist on moving surfaces in the games, but let's assume that portals are supposed to have no aversion, the games have a vanishingly small number of moving portal-able surfaces anyway so it doesn't seem as if they were stating that this is not possible.
Two thin rectangular blocks of material of the same shape hold interconnected portals. One of these blocks is inserted through the portal on the other.
Are there strange consequences at any ranges of angles or insertion distances?
For example, but not limited to, geometric impossibility, sudden intersecting, more space seeming to be accessible than exists, spacial contradiction, or a different amount of space occupied by the blocks than their size.
Such an experiment seems very hard to visualise.
It seems that it wouldn't make sense for one block to be inserted more than half way, but would the blocks always be in each others way preventing this from occurring anyway?
