There is a description of the core accretion model in the Hebrew text of Job 28:3. We make a systematic survey of the text, and bring forth this meaning.
Job 28:3 Translation
Gloom of the underworld: אֹ֣פֶל – ophel
It's surrounded by stones in thick darkness. What darkness? The gloom of the underworld, sheol, the underworld realm of the dead. The deep places of the Earth.
Gravity as a Process
Mass sinks in time, into stratified layers of sediment: a solid core on fire in the darkness, sunk in the shadow of death. (Job 28:3) MP Technical Paraphrase
