That's a portal to another universe not quite so parallel to ours. I fact its perpendicular to ours, but no worries the portal is to small to fall into.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
