The physicists talk about space
Like it was a thing with a body and face
It expands and contracts
(And these are the facts)
Yet no outline of it can be traced
--- Mike Huttner
O God, I could be bounded in a nutshell, and count myself a king of infinite space—were it not that I have bad dreams.
---From Hamlet by Shakespeare
Infinite
Infinite comes from the word finite. Finite is a relation which describes objects . . . an adjective. Objects have limits or bounds. Finite is almost synonymous with form. All objects have this primal quality called form. Form relates to what is bounded or contained from an immediate surrounding. All objects necessarily have form. And they are finite. Infinite means without bounds or limits, however strictly speaking infinite serves as an adjective, a modifier of objects. So here we have a linguistic contradiction, or an oxymoron as we say. An object without bounds or limits is impossible.
Concepts on the other hand lack this property called form. Two such concepts are Universe and space. Universe and space refer to a Concept Category. Universe and space have no boundaries or limits but we treat them as if they do anyway. In other words we reify them (convert a concept into an object) and we do this so as to name and consummate higher order abstractions via our brains.
Space refers to that which lacks form. Or we could define space as a static separation between objects, sort of similar to distance. Space has no limits or boundaries because we think space when we relate or compare two or more objects. Space is a brain-work! So we could also describe space as infinite, but strictly speaking this is rhetoric, because infinite is an adjective and space is not an object.
Universe also lacks form. Universe is a high order abstraction nesting together the notions of space and all existing objects (matter). What happened is one day a Greek or a Roman got bored. He related all the stars, and all the trees and the Earth, and all peoples and all animals, and all rocks, all things and space . . . then Eureka! He thought and named Universe or cosmos. Universe is an idea! But in modern times people started to treat Universe as if it were a finite object like a belly of a pregnant woman swelling. But if Universe is an object what contains space? More space? What is the edge of this object made out of and what is outside of it? And how does the belly swell? What object is constantly being added or created so that the belly can swell? And where does that come from?
These problems are easily solved by assuming a fundamental object that mediates light and gravity between all atoms. In this conception both the atoms and the fundamental object have form, are finite, and contain each other. Atoms contain the fundamental objects, and the fundamental objects contain atoms. They set limits or boundaries to one another. The fundamental object has form of itself. It is the finest form and has some singular qualities such as the ability to superpose, intersect or overlap up to a critical density exemplified when two protons collide. This fundamental object doesn't need human ideas such as space to retain its form. It simply is. It acts and reacts in accord with Newton's Law. It is topologically invariant if you want. This fundamental object never increases in length, width or height. Its just there. It imparts form to the atoms (in other words the atoms derive their form from these fundamental objects). This is something that space cannot possibly do. And these mediate light and gravity to and from all atoms, again a work which space cannot possibly do. Concepts, such as space cannot possibly perform causal relations such as containment or impart form or serve as the nexus of gravity or radiation. We need a form, a finite object to do such things. And we need to brainstorm it's qualities. This is what sanity calls for!The fundamental objects are like life lines beginning and ending on all protons and neutrons of the Universe and this might be the reason that the motion of the atomic 'central point' is so complex. . . If every single atom is always taking on a succession of locations(motion) then this would immediately influence every single other proton or neutron of the Universe. The proton or neutron has to constantly adjust itself or shift itself or reform itself to maintain its inherent connection to all others via the fundamental object which is probably thread-like. Its like hair. Its not like these threads are ever going to literally annihilate or be created. They are always there, just impossible to detect individually unless there is a collision of protons where all these threads fight for a single location when the threads are all bunched and crunched together. . . hence the repulsion when protons and neutrons are .7 femtometers from each other.
One cannot possibly trace a beginning or an end to a proton or a neutron (or all H atoms) because the fundamental object that converge to impart form to a single proton or neutron . . . weave all protons and neutrons continuously. There is an underlying closed circle of this fundamental object. And this object is finite.
Cosmic Microwave Background Radiation (CMBR)
Where does the CMBR fit into all this? We also need a source and mediator of the Cosmic Microwave Background Radiation. Assuming all the atoms of the Universe are connected by these fundamental objects, they would eventually end at the most distant Hydrogen atoms located at the "edges of the Universe" so to speak. These Hydrogen Atoms, call them the Omega Atoms, would assume an exotic form. Their form would not be spherical as an H atom located in the Milky Way Galaxy, since they are not fed fundamental objects from all directions of the sky. They would perhaps assume a sort of shallow angled pyramidal form. In other words these Hydrogen atoms would only have a "line of sight" or direction inwards and not outwards. They would supply fundamental objects to each and every atom located within a sphere which they themselves form. And because of their exotic form, if follows they would behave in a different mode then your run of the mill H atom in the Milky Way. Perhaps these would emit in exotic electron transitions in a consistent manner. Following from form, there signals could be more frequent, as if from the surface of a star. There is nothing dull or prosaic about these hypothesized atoms. There is nothing like them in the Universe. So with this basic idea I suggest there is no need to assume a fake black body.
Instead of a dense ball of Hydrogen fog that cools and is expanded by a concept (such as space, dark energy or whatever) we would have a thin fog of exotic H atoms, where all the fundamental objects which mediate light and gravity as well as constitute all the atoms . . . end in all directions. There are no atoms beyond the Omega Atoms. Consequently no light can pass this wall, since the nexus object which mediates light is not only inherent to all atoms, but also can only begin and end on all atoms. Thus the idea that there is a "last scattering surface" is supplanted by simply hypothesizing these exotic Omega Atoms.
These Omega Atoms are more or less evenly distributed, encircling all the stars and galaxies. These could be in a plasma like state because of their exotic form. They could be emitting in forbidden electron transitions, by way of the fundamental objects which all converge on the Planck Telescope or any other object of the Universe. The distances and density of these Omega Atoms would vary pending direction in the sky. There would still be redshift due to the exceedingly great lengths as well as nature of the unique fundamental objects interconnecting all atoms. Along these great lengths of EM Rope, the signals are less and less frequent in the way to all atoms of the Universe, including the Omega Atoms on the opposite side. And there would still be anisotropies. Galaxies would still move toward and/or away from each other via inertia.
And some of these so called Omega Atoms may be there vibrating for trillions of years. Who knows? Atoms are separated at great distances, thus there is (and was) never a threat that they would all contract into a single ball since gravity is clearly a function of distance. Due to the nature of these fundamental objects, constituting and interconnecting all atoms, gravity forcibly works in an inverse square regime. In terms of a graph there is a steep downward slope to Newton's equations. If stars or interstellar clouds are separated by great distances they will never mutually work enough pull to bring them together in a 'contraction'. It doesn't matter how large their masses are! The so called energy density thins out so to speak. In terms of gravity, stars separated by great distances work each other as if they were single hydrogen atoms with a net tug of the lowest possible ratio, namely Big G. And this is balanced out by about the same from radially all other directions. Einstein never had to add a hypothetical cosmological constant to maintain equilibrium.
With the Omega Atoms, perhaps every once in a while some are lead within the conceptual sphere of the stars and galaxies. They would reform from a sort of half spherical form to a full spherical form. And on the same token perhaps every once in a while a group of atoms within the Omega Sphere are pushed out by exotic stars or galaxies, so that they make their way out to help form it, thus becoming Omega Atoms and helping to form what we could call the Omega Wall. If we mapped out the CMBR billions of years from now perhaps it would look a little different. The so called CMB structure on the maps would appear differently because of unpredictable shifts and reformations of the Omega Wall. So I put forward this experiment. 13.8 billion years from now, launch another satellite and remeasure the CMBR. Oops I forgot . . . we won't make it that long.
If you haven't yet noticed my suggestion is like turning the Big Bang concept on its head. Its like we are in an immense spherical wall of exotic H atoms and they supply the web of zillions of these fundamental objects along which the signals are conveyed. And these converge on the satellites that study CMBR as well as all stars and galaxies, since all are interconnected, each to the other by a single fundamental object (an EM Rope). So I don't think there is any need to question the validity of the CMBR data, or redshift. All that is needed is a purge and rethinking of basic ideas.
Conclusion
It is like Nietzsche said. We really ought to get over the seduction of words! Infinite is a "god word" Undefined, misunderstood, misconceived, misused, overused, abused, confused, reified, deified, mythologized, etc. Infinite is an ontological contradiction. An oxymoron. We could use it to describe concepts since all concepts lack bounds or limits, but this is cheating and missing the point. One day some guy was fooling around with prefixes and out comes rhetoric and poetry. The physicists from a few hundred years ago pick up on this and start messing around with this word without thinking things through.
Universe is just an high order abstraction. Just an idea. Universe nests together the notions of space and of matter. Its sort of a binary conceptual system used throughout history. Universe refers to a concept category and lacks the primary quality of all objects, namely, form. And Universe, let alone space cannot possibly impart causal relations or undergo change effects such as expand, contract, accelerate, perform, inform, and so on.
