So what if the center of Antarctica is a paradise controlled by some New World Order group. It's a tropical utopia full of precious gems and expensive metals that, while providing the NWO with a super exclusive getaway, also gives them enough money to basically own the world. They've developed machines for extracting their natural treasures so no lesser individuals would ever have the ability to talk about it. Also if anyone ever did find out about it, they would probably be killed. The NWO group controls all satellite imagery and travel to and from Antarctica to make sure no one ever gets a glimpse of their paradise. Tourist adventures and scientists only go so far into Antarctica, never to the extreme middle. Since they are also involved in the government, they can control the release of information and scientific study on the continent.
One might say that "it's not possible, everyone knows the further you get away from the equator, the colder it gets... theres no paradise in the Arctic circle." True you are, however what if the NWO group has reversed the polarity of this particular spot in Antarctica, thereby reversing the weather and creating this paradise. In much the same way that Tesla was able to produce human-induced earthquakes (on a smaller scale), there is certainly a way to develop human-induced weather (farmers release chemicals into the air to create rain above their farms).
With all of this technology and with the extreme little the public actually knows about the remote and uninhabited continent of Antarctica, it is very possible that anything could be happening there and we wouldn't know about it.
