Gaseous, liquid, and solid states are matters of atomic-molecular relationships, but density is a relationship of space and mass. Density varies directly with the quantity of mass in space and inversely with the amount of space in mass, the space between the central cores of matter and the particles which whirl around these centers as well as the space within such material particles. 41:4.2 (459.6)
I am trying so hard to explain this, but it’s difficult to do with words alone. Also, I have not thought in scientific terms for many years. The matter we know as part of our everyday mortal experience is very dense. It has a relatively high amount of mass for the amount of space it takes up. The easiest way is to call it “quantum state” of matter. As a point of reference, normal matter is quantum state N=1.
The celestial objects native science calls white dwarf stars, black dwarf stars, neutron stars, and pulsars are even more dense having a quantum state N<1. Native science calls this degenerate matter. Take, for example, an object the size and mass of the sun then condense it down to the size of Urantia. It would have intense gravity on the surface. This might give you some idea of what I’m trying to describe.
Morontia matter is more diffuse. It takes up much more space for a given amount of mass. Take something the size and mass of Urantia and expand it to the size of the sun. It would have much less gravity at the surface. Point of reference quantum state N=2 or even higher. But this is not a function of protons, neutrons, or electrons. It’s all about the ultimaton and how it is arranged as the basic unit of matter.
My understanding of particle physics is mediocre at best. But I will make the attempt, even though I will probably get it wrong.
One ultimaton by itself is just that: 1 ultimaton. [like a single musical note]
2 ultimatons huddled together by harmonic resonance [like a power chord or musical fifth] is called (I believe) a tau neutrino.
3 ultimatons huddled together [like a major or minor chord] is called a neutrino.
7 ultimatons huddled together is called a photon. [like seven whole notes in one specific octave of the musical scale]
100 ultimatons huddled together in a very specific arrangement is called an electron.
183,600 ultimatons huddled together is called a proton. [the arrangement of an electron repeated 1836 times within the same space]
210,000 ultimatons huddled together is called a neutron. [the arrangement of an electron repeated 2100 times within the same space]
But all of these arrangements are a function of the manner in which the ultimaton achieves harmonic resonance by the velocity it rotates on its axis and the velocity it revolves around other ultimatons. At the smallest possible size, it becomes a complex symphony of energy which could be described as an orchestra.
What if gravity on architectural worlds is generated by artificial means? They could be hollow or any size required by the “unseen” spiritual administration of a far-flung universe. For example, a Planetary Prince might be given a very small architectural world as the location of his administration orbiting the world of his assignment.
Where is Jerusem relative to Urantia according to The Urantia Book? It’s difficult to describe “location” of morontia objects because matter is so diffuse compared to ours in that realm. On other threads, I use a “hotel” analogy to describe it.
The point where the ultimaton becomes real is the First Floor of The Orvonton Hotel. [the first dimension]
The point where ultimatons fit together forming atoms and molecules is The Second Floor of The Orvonton Hotel. [the second dimension]
The point where atoms and molecules fit together forming solids, liquids, and gases making our everyday reality is The Third Floor of The Orvonton Hotel. [the third dimension]
From our present level of reality, Jerusem is on The Fourth Floor of The Orvonton Hotel. [the fourth dimension]
Edentia is on The Fifth Floor. [the fifth dimension]
Salvington is on The Sixth Floor. [the sixth dimension]
Uversa is on The Seventh Floor. [the seventh dimension]
At each successively higher level of reality, the universe looks vastly different. As mortal beings of the third dimension, we are constrained to view reality from The Third Floor of The Nebadon Suite of The Orvonton Hotel. The arrangement is similar to concentric rings where the highest level envelopes or encompasses all the lower ones. All of this is just my opinion. Nothing more.
Anyone with a mind has an opinion and that opinion is a reflection of that mind.
