That's actually a great question, but since there's literaly nothing about the subject in all of the elder scrolls lore, I'd guess there aren't any. Or if there are and haven't been learned of yet, they might be portals to the Void. I know, black holes aren't actually holes in reality, but in game the sun and stars are holes into aetherius, so maybe.
