I'm afraid I only have relatively limited knowledge on the topic. I've only been here a month at most... What I do know is what I've already said--they're unstable areas in reality that bring in people and objects. This is only the second one I've experienced, but they tend to have... interesting effects on the surroundings and wildlife.

Supposedly they've been appearing for around a century and it's gotten to the point where there's more unstable locations than stable ones. I think the androids back at the research station could tell you more than I could...
