See what would settle it. ## Where it stands Seven answers have been proposed. None is ahead on the evidence yet. Seven are still possible. Of the one narrower question under it, none is answered yet. ## Why it matters Several mechanisms have been proposed, none tested quantitatively against the station's data⁠[[1]](https://mysteriesdept.com/sources/SRC0D0NDCWR27WJ/to-investigate-or-not-to-investigate-researchers-views-on)⁠[[2]](https://mysteriesdept.com/sources/SRC0D0NDCMY7GSG/on-the-natural-battery-hypothesis-for-the-hessdalen-lights-a).
