Note: This is relevant to inner alchemy adepts working with pre-natal Qi and Jing, which is what I think scientists are trying to describe. What’s relevant here is that they are STILL looking for particles! Duh…time to bone up on Qi Field theory…:) Michael
Search for dark matter comes up empty so far
October 30, 2013 11:21 AM EST
LEAD, S.D. (AP) Nearly a mile underground in an abandoned gold mine, one of the most important quests in physics has come up empty-handed in the search for the elusive substance known as dark matter, scientists announced Wednesday.
The most advanced Earth-based search for the mysterious material that has mass but cannot be seen turned up “absolutely no signal” of dark matter, said Richard Gaitskell of Brown University, a scientist working on the Large Underground Xenon experiment. A detector attached to the International Space Station has so far also failed to find any dark matter.
Physicists released their initial findings Wednesday after the experiment’s first few months of operation at the Sanford Underground Research Facility, which was built in the former Homestake gold mine in South Dakota’s Black Hills.
With 4,580 feet of earth helping screen out background radiation, scientists tried to trap dark matter, which they hoped would be revealed in the form of weakly interacting massive particles, nicknamed WIMPS. The search, using the most sensitive equipment in the world, tried looking for the light fingerprint of a WIMP bouncing off an atomic nucleus of xenon cooled to minus 150 degrees.
But nothing was found, said co-investigator Daniel McKinsey, a physicist at Yale University. The team plans to keep looking for another year, but McKinsey and Gaitskell were not optimistic about finding dark matter with the current setup. They are already planning to build a more sensitive experiment on the site, using a bigger tank of xenon.
“The short story is that we didn’t see dark matter interacting, but we had the most sensitive search for dark matter ever performed in the world,” McKinsey said.
The lab, in a bright, clean space at the end of an old mining tunnel filled with pipes and electric cables, is reached by a 10-minute ride in an elevator that once carried miners. Gaitskell and McKinsey said the experiment has far less radiation interference from cosmic rays than any other dark-matter lab.
Essentially, scientists are searching for something they are fairly sure exists and is crucial to the entire universe. But they do not know what it looks like or where to find it. And they are not sure if it’s a bunch of light particles that weakly interact or if it is more like a black hole.
“It’s ghost-like matter,” McKinsey said.
“We are really searching in the dark in a way,” said Harvard University physicist Avi Loeb, who is not part of the LUX team. “We have no clue. We don’t know what this matter is.”
But they keep looking. Gaitskell has been hunting for dark matter for 25 years, originally thinking the effort would take five years. “It’s like the pursuit of the Holy Grail, but hopefully this has a different outcome.”
Even more so than the recently discovered Higgs Boson, dark matter is central to the universe.
“Dark matter holds every cosmic structure in the universe together,” including our own galaxy, said University of Chicago cosmologist Michael Turner, president of the American Physical Society. Turner was not part of the LUX study.
About one-quarter of the universe is comprised of dark matter five times that of the ordinary matter that makes up everything we see. Dark matter is often defined by what it isn’t: something that can be seen and something that is energy.
Researchers are pretty sure dark matter exists, but they are not certain what it is made of or how it interacts with ordinary matter. Dark matter is vital to all the scientific theories explaining how the universe is expanding and how galaxies interact and move.
“We know there’s stuff out there that is something else and that makes these searches hugely important because we know we are missing most of the universe,” said Neal Weiner, director of the Center for Cosmology and Particle Physics at New York University, who was not part of the search.
Gaitskell and McKinsey said they looked for three “candidate WIMP events” that other teams’ experiments hinted at finding. And LUX came up completely empty, indicating that those other experiments must not have found anything.
One of the experimenters, Juan Collar of the University of Chicago, said he wanted to see the details from the LUX results before assessing how it affected his work.
The lack of success could just mean the equipment isn’t sensitive enough, so bigger, more sensitive and expensive equipment will be needed, Gaitskell and McKinsey said.
Or it could be, considering the lack of knowledge about what dark matter really is, that “perhaps we’re going in the wrong direction,” Loeb said.
He said dark matter is most likely a particle and that fits with current theory. But if it is more like a small black hole, physicists will not uncover it in this type of search. Or it may be so small, we cannot find it.November 15, 2013 at 5:02 pm #41469
A wolf, a goat, and a cabbage are to be rowed across a river in a boat holding only one of these three objects besides the oarsman. How should he carry them across so that goat should not eat the cabbage or the wolf devour the goat?

Through years of practice, Bowman could switch at a moment’s notice to this jargon-which someone had once christened “Technish”-and back again to normal speech, without clashing his mental gears. Now there was nothing to do but to wait for the confirmation, which would take at least two hours as the signals made the round trip past the orbits Jupiter and Mars.

We cannot really conceive what is meant by a phrase like “three billion years.” The history of life on earth encompasses a strech of time so vast that it defies our understanding.

The whole Taoist practice is involved with how to evoke the primordial force in order to be reunited with it in our body, Primordial Force-an aspect of Dark Matter-fills the whole universe. Dark Matter is about 96% of the universe, and the other 4% is our physical universe, . Each galaxy is a part of the Primordial Force, especially our galaxy, our solar system and our planet Earth. Our sun and Earth are part of just one solar system out of 200 billion combinations of star and planet solar systems in our Milky Way galaxy.
The Tao believes that our Earth is the energy center of the galaxies of our universe. This point of view is supported by the most advanced scientists of today in the field of quantum mechanics. According to quantum theory, one quality of subatomic particles is non-locality.’ Thus, with zero-point fluctuation as the underlying mechanism acting on quantum entities and causing one entity to affect the othersit means that every part of the universe can be in touch with every other part instantaneously. These scientists believe that the Zero Point Field’ is the all-pervasive ground state throughout the universe.
So, it really doesn’t matter where we arewe are still at the centerand each person is at the center of the universe! We are well-positioned and well-suited for the all-important process of drawing upon the primordial force for our life maintenance, refinement and evolution. Fortifying ourselves with this essential resource enables us to manifest the amazing wonders of our human birthright. And so, according to the Tao, the universe sends energy to us and to Earth so the earth can support life. Our earth stores a major part that we need in order to fulfill our birthright. Our planets also have a lot of influence on us, and all the planets store some of the elemental qualities of Primordial Force that we need to access in order to complete our inner alchemy transformation.
In 1928, British physicist Paul Dirac wrote down an equation that combined quantum theory and special relativity to describe the behaviour of an electron moving at a relativistic speed. The equation would allow whole atoms to be treated in a manner consistent with Einstein’s relativity theory. Dirac’s equation appeared in his paper The quantum theory of the electron, received by the journal Proceedings of the Royal Society A on 2 January 1928. It won Dirac the Nobel prize in physics in 1933.
As a by-product of this same view, I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, “Feynman, I know why all electrons have the same charge and the same mass” “Why?” “Because, they are all the same electron!” And, then he explained on the telephone, “suppose that the world lines which we were ordinarily considering before in time and spaceinstead of only going up in time were a tremendous knot, and then, when we cut through the knot, by the plane corresponding to a fixed time, we would see many, many world lines and that would represent many electrons, except for one thing. If in one section this is an ordinary electron world line, in the section in which it reversed itself and is coming back from the future we have the wrong sign to the proper timeto the proper four velocitiesand that’s equivalent to changing the sign of the charge, and, therefore, that part of a path would act like a positron.” “But, Professor”, I said, “there aren’t as many positrons as electrons.” “Well, maybe they are hidden in the protons or something”, he said.

Here I have impression that one should be in the right way modest especially if one is not scientist and also even one is, not specialist in cosmology.
Whether dark energy or dark matter, but anyway mysterious forces working even at supergalactic level or at extremely tiny scales one should clearly make the effort to understand situation in it’s own terms.
Ps. Sorry for my broken English.
