I personally do not find a great deal of resonance with most theories and beliefs which circulate concerning the hollow (inner) earth, many of which are somewhat "conspiracy theory" in nature. The links below lead to a few websites I have found on the topic that seem more middle-of-the-road, although I have not thoroughly researched any of them. I am not sure that any of these sources include the concept that the interior hollow is removed from the surface earth's dimensional physicality through the natural process of moving toward the center of the magnetic sphere. Yet I stress once again, my view of the Interior planet is based purely on my akashic perception and personal pseudo-experiences.
