Up before eight, breakfast and the paper. Very cloudy, gloomy morning, but the buds on the honeysuckle and crab apple trees are popping, and yesterday while driving you saw the leaves out on a weeping willow – sure signs of Spring, though it may snow tomorrow.
Unsure, you are, of loop quantum gravity and causal dynamical triangulation.
It’s a mite early for that sort of thing, Amorella. I like to have material sink in, to become a part of it, if you will. And, I feel this need to work on the book, plus I haven’t made a audio draft of chapter six yet.. . . I just really got the joke. Yoda speak. Funny. It takes away the gloomy day and brings a smile. This incident reminds me of my days as a kid with my imaginary friend, Aunt Jemima. She would say things that would put a different perspective or light on the subject at hand and I would smile in the same way. Living was always easier with Aunt Jemima as a friend and now I have you. I guess it is just my way to cope with the universe at large.
You need your sense of humor, orndorff, even if it is gallows humor. Some say gallows humor is mentally unhealthy but from in here it is much healthier than the alternative. And this immediately reminds you of Milton. “The mind is its own place and in itself, can make a Heaven of Hell, a Hell of Heaven.” Later today, we can relate this to gravity and dark matter/energy. – Amorella.
The rains begin as you ‘speak’ Amorella. Spake . . . "Thus Spake Zarathustra” by Nietzsche. And, the beginnings of a famous quotation in the Prologue:
The saint laughed at Zarathustra, and spake thus: "Then see to it
that they accept thy treasures! They are distrustful of anchorites,
and do not believe that we come with gifts.
The fall of our footsteps ringeth too hollow through their streets. And just as at night, when they are in bed and hear a man abroad long before sunrise, so they ask themselves concerning us: Where goeth the thief?
Go not to men, but stay in the forest! Go rather to the animals! Why not be like me - a bear amongst bears, a bird amongst birds?"
"And what doeth the saint in the forest?" asked Zarathustra.
The saint answered: "I make hymns and sing them; and in making hymns I laugh and weep and mumble: thus do I praise God.
With singing, weeping, laughing, and mumbling do I praise the God
who is my God. But what dost thou bring us as a gift?"
When Zarathustra had heard these words, he bowed to the saint and said: "What should I have to give thee! Let me rather hurry hence lest I take aught away from thee!" - And thus they parted from one
another, the old man and Zarathustra, laughing like schoolboys.
When Zarathustra was alone, however, he said to his heart: "Could it be possible! This old saint in the forest hath not yet heard of it,
that God is dead!"

I remember the old joke someone once scribbled on a near university’s dive bathroom wall:
God is dead. – Nietzsche
Nietzsche is dead. – God
Good place for a break, post. – Amorella.
In checking your email you found Doug sent you a note and several helps. Here is his note and bits can be gathered from his source helps also. First, the note:
Dick, I read your blog this morning with interest. Good background information and represents what I think we know so far about dark matter. You may want to look up WIMP's. I think this stands for a weakly interacting massive particle.
If you will check, you will find that dark matter is also needed to explain the rotation of stars in the galaxies. Unlike a gravitational system the stars far from the center are rotating at the same speed as the stars close in. In a gravitational system the stars far out should be moving slower. Thus the need for missing mass to explain why the stars are all rotating at the same speed. Note if gravity acted like a one over R system the stars would all rotate at the same speed. Some are working on this possibility but are not well accepted by the main stream of scientists. Newton cannot be violated! Also, this "new gravity" does not explain all the observations but I do not what area the theory is deficient in. Look forward to you further work in this area.
Doug

In astrophysics, weakly interacting massive particles or WIMPs, are hypothetical particles serving as one possible solution to the dark matter problem. These particles interact through the weak force and gravity, and possibly through other interactions no stronger than the weak force. Because they do not interact with electromagnetism they cannot be seen directly, and because they do not interact with the strong nuclear force they do not react strongly with atomic nuclei.
This combination of properties gives WIMPs many of the properties of neutrinos, save for being far more massive and therefore slower. –

Dick, Here is something to think about. The Big Bang stated as a single point. No volume. Also it stated about 13.75 billion years ago, Given the inflationary period and the speed of light how did it become at least 93 billion light years across in 13.75 billion years?
Answer: According to general relativity, space can expand faster than the speed of light, although we can view only a small portion of the universe due to the limitation imposed by light speed
My question is: what is expanding if space is empty space?
Source:
Current interpretations of astronomical observations indicate that the age of the universe is 13.75 ±0.17 billion years,[4] and that the diameter of the observable universe is at least 93 billion light years or 8.80×1026metres. [5] According to general relativity, space can expand faster than the speed of light, although we can view only a small portion of the universe due to the limitation imposed by light speed. Since we cannot observe space beyond the limitations of light (or any electromagnetic radiation), it is uncertain whether the size of the universe is finite or infinite.

Wow! This is a good question. I assume it is dark matter or dark energy. I am going to have to absorb this first. All this is really interesting. Plus, Doug gave me another source from Wikipedia “Universe”. I have downloaded it to read first. This is really good stuff. What it would be to be a kid now, and have the Internet at your disposal.
Post. After you do your reading I will go over this in sections. – Amorella.
What is so cool is that “the mind” exists in (on, over, through, around) all this. This is most awesome. I mean, it is something everyone “knows” yet surely there is more significance to it than that, at least for a fiction or two.
Mid-afternoon. You and Carol took a break from housework – had an ice tea and cookie and you bought a new cane uptown. Coming home a burst of sky ice. You picked up three of three-fourth’s inch sized ice balls. You have been editing under my direction material from “Universe – Wiki”.
I am excited to see the ancient Greeks in part of the mix and the sense of seven multiple universes. As I read I try to comprehend the concept of the possibility of the mind running through all these universes, not at once, mind you, but through levels like sheets of paper. – The mind picks up the edges of the multiple universes as they are ‘stacked’ but appearing bound as one unit.
Good. Post. – Amorella.
A break for some reading, then noting Elizabeth Taylor’s passing earlier today you ‘personified’ her character through two films, both with Richard Burton, her husband in real life twice. The Taming of the Shrew (1967) with Burton as Petruchio and Taylor as Katharina is one you used for years as a Shakespearian comedy to counter MacBeth and/or Hamlet. And, for you, the sobering drama, Edward Albee’s, Who’s Afraid of Virginia Woolf? (1966) with Burton playing George and Taylor playing Martha. Both were brilliantly played by both actors.
That is how I will remember them. And, why I use both as ‘icons’ in The Rebellion? Burton as Salamon and Taylor as Kassandra. Easy to picture each one in character that way. I suppose it is a form of cheating in a way. But it makes the characters more alive and fun for me. Most students enjoyed Taming of the Shrew even though it involved an essay comparing a modern movie comedy, Notting Hill (1999) (comparing and contrasting of comedic elements), a treat the last couple of days of the school year. So, from me, a tip of the old beret to Burton and Taylor, R.I.P.
Post. - Amorella.
Almost twenty-one hundred hours and I have been editing material that will prove useful in the books. Below is the editing result of “Universe” in Wikipedia.

An alternative interpretation of unvorsum is "everything rotated as one" or "everything rotated by one". In this sense, it may be considered a translation of an earlier Greek word for the universe, περιφορά, "something transported in a circle", originally used to describe a course of a meal, the food being carried around the circle of dinner guests.[8] This Greek word refers to an early Greek model of the universe, in which all matter was contained within rotating spheres centered on the Earth; according to Aristotle, the rotation of the outermost sphere was responsible for the motion and change of everything within. It was natural for the Greeks to assume that the Earth was stationary and that the heavens rotated about the Earth, because careful astronomical and physical measurements (such as the Foucault pendulum) are required to prove otherwise.

Definition as reality
The three elements of the universe (spacetime, matter-energy, and physical law) correspond roughly to the ideas of Aristotle. In his book, The Physics, (from which we derive the word "physics"), Aristotle divided (everything) into three roughly analogous elements: matter (the stuff of which the universe is made), form (the arrangement of that matter in space) and change (how matter is created, destroyed or altered in its properties, and similarly, how form is altered). Physical laws were conceived as the rules governing the properties of matter, form and their changes.
Definition as connected space-time
It is possible to conceive of disconnected space-times, each existing but unable to interact with one another. An easily visualized metaphor is a group of separate soap bubbles, in which observers living on one soap bubble cannot interact with those on other soap bubbles, even in principle. According to one common terminology, each "soap bubble" of space-time is denoted as a universe, whereas our particular space-time is denoted as the universe, just as we call our moon the Moon. The entire collection of these separate space-times is denoted as the multiverse.[15] In principle, the other unconnected universes may have different dimensionalities and topologies of space-time, different forms of matter and energy, and different physical laws and physical constants, although such possibilities are currently speculative.
Definition as observable reality
According to a still-more-restrictive definition, the universe is everything within our connected space-time that could have a chance to interact with us and vice versa. According to the general theory of relativity, some regions of space may never interact with ours even in the lifetime of the universe, due to the finite speed of light and the ongoing expansion of space. For example, radio messages sent from Earth may never reach some regions of space, even if the universe would live forever; space may expand faster than light can traverse it. It is worth emphasizing that those distant regions of space are taken to exist and be part of reality as much as we are; yet we can never interact with them. The spatial region within which we can affect and be affected is denoted as the observable universe. Strictly speaking, the observable universe depends on the location of the observer. By traveling, an observer can come into contact with a greater region of space-time than an observer who remains still, so that the observable universe for the former is larger than for the latter. Nevertheless, even the most rapid traveler may not be able to interact with all of space. Typically, the observable universe is taken to mean the universe observable from our vantage point in the Milky Way Galaxy.

The universe is believed to be mostly composed of dark energy and dark matter, both of which are poorly understood at present. Less than 5% of the universe is ordinary matter, a relatively small contribution.
**
According to the prevailing Standard Model of physics, all matter is composed of three generations of leptons and quarks, both of which are fermions. These elementary particles interact via at most three fundamental interactions: the electroweak interaction which includes electromagnetism and the weak nuclear force; the strong nuclear force described by quantum chromodynamics; and gravity which is best described at present by general relativity.
**
High-precision test of general relativity by the Cassini space probe: radio signals sent between the Earth and the probe are delayed by the warping of space and time due to the Sun’s mass.
Of the four fundamental interactions, gravitation is dominant at cosmological length scales; that is, the other three forces are believed to play a negligible role in determining structures at the level of planets, stars, galaxies and larger-scale structures. Since all matter and energy gravitate, gravity's effects are cumulative; by contrast, the effects of positive and negative charges tend to cancel one another, making electromagnetism relatively insignificant on cosmological length scales. The remaining two interactions, the weak and strong nuclear force, weak and decline very rapidly with distance; their effects are confined mainly to sub-atomic length scales.

Depiction of a multiverse of seven “bubble” universes, which are separate spacetime continua, each having different physical laws, physical constants, and perhaps even different numbers of dimensions or topologies.
Some speculative theories have proposed that this universe is but one of a set of disconnected universes, collectively denoted as the multiverse, altering the concept that the universe encompasses everything.[15][73] By definition, there is no possible way for anything in one universe to affect another; if two "universes" could affect one another, they would be part of a single universe. Thus, although some fictional characters travel between parallel fictional “universes”, this is, strictly speaking, an incorrect usage of the term universe.
The disconnected universes are conceived as being physical, in the sense that each should have its own space and time, its own matter and energy, and its own physical laws — that also challenges the definition of parallelity as these universes don't exist synchronously (since they have their own time) or in a geometrically parallel way (since there's no interpretable relation between spatial positions of the different universes). Such physically disconnected universes should be distinguished from the metaphysical conception of alternate planes of consciousness, which are not thought to be physical places and are connected through the flow of information.
There are two scientific senses in which multiple universes are discussed. First, disconnected spacetime continua may exist; presumably, all forms of matter and energy are confined to one universe and cannot "tunnel" between them. An example of such a theory is the chaotic inflation model of the early universe.[75] Second, according to the many-many-worlds hypothesis, a parallel universe is born with every quantum measurement; the universe "forks" into parallel copies, each one corresponding to a different outcome of the quantum measurement. However, both senses of the term "multiverse" are speculative and may be considered unscientific; no known experimental test in one universe could reveal the existence or properties of another non-interacting universe.

You have been reading and gaining more understanding. So far in these books there is a rationale, order and consistency to the metaphysics and the physics. This is going to be no different. Each will be kept separate which is one of the reasons this following quotation from Wikipedia is so important: “Such physically disconnected universes should be distinguished from the metaphysical conception of alternate planes of consciousness, which are not thought to be physical places and are connected through the flow of information.”
Tomorrow I will explain more and make it more relevant to the upcoming scene in chapter seven. Post. – Amorella.
