We have no physical evidence of anything
that is not true. there is lots of evidence and data from echo soundings and seismic reflection.
If we bounced a seismic wave at New Jerusalem, if it were up in the sky, and we could do that, how would it look? How do you know that????? Shouldn't you know what you are talking about? You are simply saying, in effect, 'I believe that the inner earth is just like the surface, physical only' Waves cannot tell you that.
What else you got???
other techniques such as:
"Geophysicists can also make maps of other physical properties that rocks show over an area. Gravitational pull, magnetic field strength, electrical conductivity, radioactivity, and spectral reflectance are all properties that may be used to detect particular rock formations of economic or geologic interest, even if they are buried below the surface."

From your link
"The fact that the Earth has a magnetic field is an independent piece of evidence for a molten, liquid core. A compass magnet aligns with the magnetic field anywhere on the Earth.
The earth cannot be a large permanent magnet, since magnetic minerals lose their magnetism when they are hotter than about 500 degrees C. Almost all of the earth is hotter, and the only other way to make a magnetic field is with a circulating electric current."
So, the assumption is that only things physical are involved. If there is also spiritual in the mix there, could we get power without the hot theorized way they claim? If not, why not, precisely, and how would you know????? You likely know NOTHING about the spiritual properties, and abilities, and laws etc. No, unless, and until you do, which would be never in this life, we have to strike that one. Anything else?
but to say we have no data, therefore the theory that hell exists in the core of the earth is scientifically entertainable, is simply and completely wrong.
Oh we have a little data, but we need to interpret that. Now, if you had been there, and run tests, and observations, and told us it was just like the surface, and physical only, under only the same laws, why, I would have to consider the evidence. That is not the case, you simply assume and believe certain things. But so do I. That is not science.
