Well, if you wanna go psychic with this, these would be portals. But, Its a naturally created monodimensional displacement entrance that, according to what you want to know, would take you to somewhere else in this universe. Well, saying the description, it seems possible, though it may not be artificial... ;P

Yes, it is possible.
