Uh, Quahog, you are, one would hope, aware that there is NO solid earth anywhere near the North Pole. It is merelya point on an ice cap that floats on top of the Arctic Sea. And that is all there is for hundreds of miles around the pole, Which means that, if there were a hole, it would have to be at the bottom of the Arctic Ocean. And a giant hole at the bottom of an ocean above a hollow earth would in fact have long since drained the Arctic Ocean, as well as the Bering Sea, and a large part of the North Atlantic. None of which have been drained. And all we would have there today would be an Arctic Ice Field. We don't. Ther US Navy ran periodic voyages in nuclear subs for decades under the Arctic ice cap and under the point on the icde where the North Pole is.. They didn't run aground suddenly. They didn't get sucked by a vortex into a hollow earth. The Danish Air Force has run regular flights over the whole ice cap for decades, monitoring the extent and composition of the ice cap. ?They have NEVER reported a giant mysterious hole, and they've gone everywhere up there. Pretty shaky case you've got going.
And I've seen a lot of satellite photos of the South Pole and Antarctica as a whole, and there have NEVER been any giant mysterious holes in those pictures. Where. oh where, are these giant holes hiding?
