>> Seismic shear-waves (S-waves) cannot travel through liquid, yet they travel through all of the Earth's crust and mantle – they are stopped by the core, telling us that the outer core is liquid. They do not show us your layers. << Why would the shear waves not penetrate the liquid layers? The pressures at those depths would give the liquids high densities that should propagate the waves. I don't understand the exact difference in the shear waves that would make them not travel through high density liquids can you help me here? If the inner core of the earth is composed of super dense pre-elemental material that may not transmit the waves and the waves are transmitted through the balance of the layers then the same results would occur.
