Seismological data shows different zones of density within the Earth which match the description of Earth's interior given us by Jesus in Luke 16:19-31, the parable of the rich man and Lazarus.
If P-waves (sound waves) travel in straight lines then why are the lines depicting their paths through the interior of the Earth curved in the popular science interpretation of data from seismic waves (SciPop)?
Having a value for Earth's average density is critical to the popular science (SciPop) model for its internal structure because we can't see inside the Earth, we can only infer what we think it's structure may be.
The popular science (SciPop) rationalization for the liquid outer core is an ephemeral strand of wispy logic. It predates Stephen Hawking but it's an example of the Hawking Effect. All it has to do is sound plausible.
Calculating the mass of the Earth takes circular reasoning and an assumption based on circumstantial evidence. It falls apart when you try to prove that there's no open space inside the Earth.
Based on seismological data and the Matty's Paradigm spherical hollow Earth model (SHEM) we can definitively say that Abraham and Lazarus are in a chamber in the lower mantle. The rich man is in the molten core of the Earth.
According to Jesus there's a great gulf of open space between the inner surface of the lower mantle (Abraham's bosom) and the surface of the molten core of the Earth (the lowest hell).
Evolution is the passage of heritable traits from generation to generation, it requires billions of years of death and dying before humans could sin. The Bible says that there was no death before sin.
