Both energetically and physically, the planet’s center is a very different space:
Describing a “black hole phenomenon” at the Center of the Earth:
“When I reached what appeared to be the center, or heart, of the earth, the energy was so different from that of the earth’s outer crust that it almost shocked my system. I knew I had to keep moving, that I could not stand too much of the earth-core energy at one time.” (R. McKnight, Cosmic Journeys, p. 71)

Describing the center of the physical Earth (in reference to an 8+ magnitude earthquake in Bolivia, 1994):
“The chemical structures of rocks, magma, and crystals can be analyzed by studying the seismic waves passing through them…Scientists detected and measured the waves generated by the quake that traveled through the center of Earth and out to the opposite side…they were amazed at their findings: The center of Earth is a huge iron core crystal that is about 1,500 miles wide and is denser than the surrounding outer core, mantle, lithosphere, and crustal zones.” (B. Hand Clow, Alchemy of Nine Dimensions, p. 5)
