Subs, without getting into theological areas and staying with known physics, sunspots are simply areas of lower temperatures in the photosphere of the Sun, causes by vortices in the circulation of same. Worm-holes although much speculated about especially in science fiction are not proven. No-0ne knows where you go if you pass through a black hole without being torn to pieces by tidal forces. Faster than light travel is in no way comparable to passing through the "sound barrier". That was purely a characteristic of travel in a gaseous medium. The Universe itself does not permit any object to travel at light speed. your Tau simply grows larger and larger, but to attain the speed of light would entail massing the same as the entire universe.
