  In this paper we present unsolved problems that involve infinite tunnels of
recursive triangles or recursive polygons, either in a decreasing or in an
increasing way. The "nedians or order i in a triangle" are generalized to
"nedians of ratio r" and "nedians of angle {\alpha}" or "nedians at angle
{\beta}", and afterwards one considers their corresponding "nedian triangles"
and "nedian polygons". This tunneling idea came from physics. Further research
would be to construct similar tunnel of 3-D solids (and generally tunnels of
n-D solids).
