During the formation of planet Earth, the action of the particles moving to form the core of the Earth is pictured in the sense of sinking into darkness and obscurity.
Darkness: לַחֹ֗שֶׁךְ – choshek
To put, place, set: שָׂ֤ם – sum
Setteth: שָׂ֤ם - sum [to put, place, set] The mass is in motion. It has been set in a place or it is in motion towards the place where it is to be set. This is the 3rd Hebrew concept of gravity which we have identified.
At the end of time: קֵ֤ץ – qets
This means end, limit, of space or time. Could we be talking about the end of all mass? Or are we talking about the end of time, as in, time stops?
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
A Pearl of Great Price
We had a dream recently (September 19, 2020). We saw a pearl. In the dream we were shown that the formation of a pearl is a picture of core accretion and planet formation.
