Notes - wild theory / dark matter / (final) Pouch 11

         Early you had blood work done for Dr. B. For lunch you ate at Panera/Chipotle – both places were quite busy because it is Martin Luther King Day and schools are not in session. Your appointment is at two-thirty but Carol is at Hallmark at the VOA Centre before you head home. The medical offices are connected with the north end of Mason High School directly east of the city building at 6010 Mason-Montgomery Road.

         1336 hours. I hope I can continue typing without too much trouble. Paul says it is a very minor operation. Today was an excellent day for waking up. BBC has a wonderful article on Dark Matter and the first photograph of its existence.

         The point is that both you and Doug feel that the universe is ‘alive’. – Amorella

         I would have to define life but I think it is alive in the way that some feel the earth is alive, that it has a consciousness of being because it is an organic/inorganic system of which we are a part. If this is so then it would seem to me that eventually we could graduate our human consciousness to a level where we are more acute aware of this. If this is so then why wouldn’t it be possible to tap this dynamic source and use it to communicate with each other, maybe with the assist of computer machinery. If the computer can be created to have a consciousness-of-being because it is a system, then it could possibly tap into this. If so, in this setting time and space would not necessarily exist a puddle if you will within the realms of Quantum Mechanics and Chaos Theory. Perhaps there is a nervous system of sorts. Channels like brain synapses – electrical-like energy we have not searched for. This is more in the analogous range of imaginary considerations, but it seems possible though not that probable. I don’t know if this can be useful in the Merlyn books or not, something to mention as a suggestion and nothing more. Analogies can be deceptive because of particular definitions of words. In a way though this makes metaphysics less esoteric to me, it makes it more of the natural process, like the mechanics of building a baseball, the world and the universe as objects of their own purpose, not ours, unless we would be considered a part of the overall purpose of filtering or sifting the ‘spirit’ if you will into the ‘physical’ world, the Before Creation with the Present Creation. I want to say a ‘higher plane’ but perhaps it is ‘the very lowest of planes such as the lowest of sound waves – unknown frequencies. (1403) Wow. I have to go find Carol, we need to get back.

         You passed the carpel tunnel tests in both arms. You were concerned that I would go away with all the electrics running through your arm nerves to the hands, and told him so. After that office visit you had to go back and run through another test that was misplaced this morning so it has been a busy day.

         1620 hours. This is the article on dark matter.

Cosmic 'web' seen for first time
By Simon Redfern
Reporter, BBC News


An intense quasar can, like a flashlight, illuminate part of the surrounding cosmic web


The hidden tendrils of dark matter that underlie the visible Universe may have been traced out for the first time.

Cosmology theory predicts that galaxies are embedded in a cosmic web of "stuff", most of which is dark matter. Astronomers obtained the first direct images of a part of this network, by exploiting the fact that a luminous object called a quasar can act as a natural "cosmic flashlight". Details of the work appear in the journal Nature.

The quasar illuminates a nearby gas cloud measuring two million light-years across. And the glowing gas appears to trace out filaments of underlying dark matter. The quasar, which lies 10 billion light-years away, shines light in just the right direction to reveal the cold gas cloud. For some years, cosmologists have been running computer simulations of the structure of the universe to build the "standard model of cosmology".

They use the cosmic microwave background, corresponding to observations of the very earliest Universe that can be seen, and recorded by instruments such as the Planck space observatory, as a starting point. Their calculations suggest that as the Universe grows and forms, matter becomes clustered in filaments and nodes under the force of gravity, like a giant cosmic web.

The new results from the 10-metre Keck telescope in Hawaii, are
reported by scientists from the University of California, Santa Cruz and the Max Planck Institute for Astronomy in Heidelberg.
They are the first direct observations of cold gas decorating such cosmic web filaments.

The cosmic web suggested by the standard model is mainly made up of mysterious "dark matter". Invisible in itself, dark matter still exerts gravitational forces on visible light and ordinary matter nearby.
Massive clumps of dark matter bend light that passes close by through a process called gravitational lensing, and this had allowed previous measurements of its distribution. But it is difficult to use this method to see very distant dark matter, and cold ordinary matter remains tricky to detect as well.

The glowing hydrogen illuminated by the distant quasar in these new observations traces out an underlying filament of dark matter that it is attracted to it by gravity, according to the researchers' analysis.
"This is a new way to detect filaments. It seems that they have a very bright quasar in a rare geometry," Prof Alexandre Refregier of the ETH Zurich, who was not involved in the work, told BBC News.
"If indeed gravity is doing the work in an expanding Universe, we expect to see a cosmic web and it is important to detect this cosmic web structure."

In the dark

He added: "What is expected is that the dark matter dominates the mass and forms these structures, and then the ordinary matter, the gas, the stars and everything else trace the filaments and structures that are defined by the dynamics of the dark matter."

"Filaments have been detected indirectly before using gravitational lensing, which allows us to see the distribution of the dark matter.
"Part of the ordinary matter has formed stars, which we can see, but another component is the gas. If the gas is very hot it emits X-rays and can be seen using X-ray telescopes. Other techniques to detect cooler gas now include the method described here."

Sebastiano Cantalupo, lead author of the article, and others have used the same method previously to look for glowing gas around quasars, and had seen dark galaxies. "The dark galaxies are much denser and smaller parts of the cosmic web. In this new image, we also see dark galaxies, in addition to the much more diffuse and extended nebula," Dr Cantalupo, from UCSC, explained.  "Some of this gas will fall into galaxies, but most of it will remain diffuse and never form stars.”

"The light from the quasar is like a flashlight beam, and in this case we were lucky that the flashlight is pointing toward the nebula and making the gas glow. We think this is part of a filament that may be even more extended than this, but we only see the part of the filament that is illuminated by the beamed emission from the quasar."
While the observations support the cosmological simulations' general picture of a cosmic web of filamentary structures, the researchers' results suggest around 10 times more gas in the nebula than predicted from typical computer simulations.

They postulate that this may simply be due to limitations in the spatial resolution of the current models, or, more interestingly perhaps, may be because the current grid-based models are missing some aspect of the underlying physics of how galaxies form, evolve, and interact with quasars.

"We now have very precise measurements of the amount of ordinary matter and dark matter in the Universe," said Prof Refregier.
"We can only observe a fraction of the ordinary matter, so the question is what form the remainder takes. These results may imply that a lot of it is in the form detected here."

         Work on Pouch Eleven tonight. You’ll have time. Post. - Amorella

          2140 hours. Surprisingly, this draft was not so bad.

         Drop it in and post. Snow tonight. Enjoy the rest of the evening as much as you did watching last night’s PBS’s Abbey and Sherlock shows. – Amorella

            Walking around from what appeared to be a curtain, Yermey came into view about five yards in front of the Cessna. He waved and smiled. Then he jumped up and down on the earth a couple of times and said, "The floor is solid; it will be fine."
            "It looks like grass, like a grass runway," said Pyl as she opened the door. Blake was right behind her. Friendly followed, then Hartolite and Justin. Pyl put her hand down and touched the grass. "It is real grass . . . and dirt."
            Blake grumbled, "I don't remember putting the wheels down. I had just put them up."
            "Where are we?" stated Justin.
            Yermey reached out with good will and shook Pyl's hand first. "Welcome to our abode."
            "This is a giant hanger with grass growing in it," declared Blake, "I'll be damned if it isn't. How'd we get here? I don't remember landing."
            "I think things are not as they seem. I think we have been abducted," asserted Justin.
            "You are not abducted, though it may seem that way," replied Friendly. "We need to talk, and this is the safest place."
            "For you, maybe," charged Justin. "Where are the windows?"
            Pyl in restrained anguish responded, "Calm down," Justin."           
            Blake directed his question to Hartolite, "Are we really abducted Carlson?"
            "No, you are not. My real name is Hartolite not Carlson."
            "Why the deception?" retorted Justin in growing anger, focused in part on Pyl's comment to calm down.
            "First, let's show you where you are," said Yermey politely.
            Looking at Pyl for a comeback, Justin quietly bemoaned, "They are probably going to gut us and have us for dinner. That's the best outcome I can think of."
            Friendly smiled towards Pyl. "Yermey put real dirt on the floor," she said, "this is real earth grass because we want you to feel comfortable. You are our guests and you will be treated well."
            "Not well cooked," noted Yermey, then he quipped with a fun face, "We are not cannibals."
            "We hold the same virtues you do," said Hartolite. "This is why we are here."
            "Let's go over to your apartment if you choose to stay aboard; otherwise this will be a short stay. You are not going to be harmed in any way. If after we explain and respond to your questions you will be allowed to return to your Cessna and will see to it that you will be loosed into the lower air with everything functioning, to land at Burke which is only a mile or two away."
            "Are you going to take our memories away?" asked Justin in a slight but direct voice.
            "No need," said Yermey. "This is not science fiction. No one will believe you if you tell what you are experiencing here. Why would they?"
            "They wouldn't, that's the point. I am not so trustful," answered Justin.
            Ship interjected for the first time, "Trust is what we do, Justin, this is what I, the machinery, am built for."
            I am built to know and understand the captain and crew whom I protect. I am in loco parentis just as a public school teacher in your culture. It is my job to keep you safe from harm first. We have no weapons. We have no need of a military presence at home or here. We are runners by the same nature that you are stand-and-fighters.
            "Parents?"
            "The marsupial-humanoids, as you will come to call us, are run like a single family household in your culture. We are the same species thus we treat each other as family."
            Blake chuckled, "We have problems in and between our families."
            "As do we, that's why we have a committee of twelve with two Parents elected once and only once every twenty years, a male and female. Three judges in courts clarify disputes. Our institutions are similar. Our practical form of Family has worked for us for fifteen thousand years but we have no wish to impose our culture onto yours. We would rather run first. I, Ship, am built for safety and for running first in the process."
            Friendly interposed, "Ship welcomes you. He will protect you and your culture while on board. If bad comes to worse, we will drop you off safely, with your plane fully intact and running and we will run off too."
            Anticipating Justin's next question Blake asked, "What if one of you attempted to harm us?"
            "Ship would protect you first as you are our guests, and us second."
            Justin stood surprised, finding he trusting this machinery first just like he would trust his car before he would trust a stranger to drive it.
