I don't know. The information on the matter suggests an alien race living on the other side of the North Pole's entrance/exit indeed. Perhaps that other world is like a paradise in comparison to our known Earth? If that's the case and if people all over the world knew about it, who would stop the Earth refugees from going to that paradise? You see what's happening to Europe due to sandnigger wererefugees swarming the whole place due to the activities of ISIS. They're destroying the Europe. Similar thing would happen to that "other world" beyond the North Pole opening when all earthlings started to travel there in hope of better life. It has to be kept in secret because human beings are so dumb that they wouldn't be able to populate a paradise-like place in a peaceful manner. They would just ruin it. At least here in the junk yard Earth which is actually a prison, we will just kill each other but out there we might harm something that deserves protection (unlike mankind).
