Paul, sorry, previous post was written without my usual three or more edits in attempts to make things better understandable, or just sound sane.  Notice though the last post was finished at 9:05am, I was to meet somebody at 9:00am.  Returning, I found an article written a year before I read about it, probably took that much time to make the info a part of a book, and being kinda new, was not discussed a whole lot, also probably because of this mentioned in the article in 2006.

Quote:
The Cambridge University team expects to submit the first of its results to a leading astrophysics journal in the next few weeks.

...

"The distribution of dark matter bears no relationship to anything you will have read in the literature up to now," explained Professor Gilmore.

The points I pick up from this article matches in many ways what was what I had later read.  Some of them being:

Quote:
But now an Institute of Astronomy, Cambridge, team has at last been able to place limits on how it [dark matter] is packed in space and measure its "temperature".

"It's the first clue of what this stuff might be," said Professor Gerry Gilmore. "For the first time ever, we're actually dealing with its physics," he told the BBC News website.


Mentioned in an earlier post with halos and temperature.


Quote:
Science understands a great deal about what it terms baryonic matter - the "normal" matter which makes up the stars, planets and people - but it has struggled to comprehend the main material from which the cosmos is constructed.


A general statement, of course saying dark matter is a mystery.


Quote:
Astronomers cannot detect dark matter directly because it emits no light or radiation.


This, too.


Quote:
Its presence, though, can be inferred from the way galaxies rotate: their stars move so fast they would fly apart if they were not being held together by the gravitational attraction of some unseen material.


Mentioned earlier, recounted from its history since Zwicky in 1933.


Quote:
The Cambridge efforts have produced an additional, independent result: the detailed study of the dwarf galaxies  has allowed the scientists to weigh our own galaxy more precisely than ever before.

"It turns out the Milky Way is more massive than we thought," said Professor Gilmore.

"It now looks as though the Milky Way is the biggest galaxy in the local Universe, bigger even than Andromeda. It was thought until just a few months ago that it was the other way around."


This is what I mean by inferred and visible being deceiving, because of the turn-around on which galaxy is bigger since, but notice again, this study was on dwarf galaxies perhaps not suitable in a search for dark matter, because as it mentions:

Quote:
"It looks like you cannot ever pack it [dark matter] smaller than about 300 parsecs - 1,000 light-years; this stuff will not let you. That tells you a speed actually - about 9km/s - at which the dark matter particles are moving because they are moving too fast to be compressed into a smaller scale.

"These are the first properties other than existence that we've been able determine."


This why it may be dwarf galaxies are unlikely candidates if searching for dark matter and not part of the hunt, they can be too small, or if larger than this, too sparse in amount as to be detectably relevant in its mass.  This is why I kept the conversation on galaxies and clusters.  Here also explains why:

Quote:
"If this temperature for the dark matter is correct, then it has huge implications for direct searches for these mysterious particles (it seems [science] may be looking in the wrong place for them) and for how we thought the galaxies and clusters of galaxies evolve in the Universe.

"Having 'hotter' dark matter makes it harder to form the smallest galaxies, but does help to make the largest structures  This result will generate a lot of new research."





Quote:
The most likely candidate for dark matter material is the so-called weakly interacting massive particle, or Wimp.


This relates back to a further comment on Colin's original mention of a MN detection base where absolute zero is used.  This also.

Quote:
Experimental crystal detectors placed down the bottom of deep mines are hoping to record the passage through normal matter of these hard to grasp dark matter particles.



Could be the CERN and Lawrence Livermore projects:

Quote:
Researchers would hope also that future experiments in particle accelerators will give them greater insight into the physics of dark matter.


Of course the article explains all this, but just wanted to show how this early article has related closely to information I had learned of afterward and as noticed doesn't make mention of infrared/ultraviolet for some reason.  So what you last posted was strange to me but from what mention I've read, a dwarf galaxy was in common.  That was all I could comment about it.

So exactly what are you saying???
Is it there or is'nt it can you see, feel, smell or touch it.
Sounds like an over elaborate excuse of wasting funds to me.
Giz a job will ya.
cern were looking for a magnetic core sweeper upper, and i did apply but it required experience of nanno particle mopping and a bit of out of hours sub cooling cabinet cleaning, (These boffs just love their ice creams)
Any use for 9000 gauss bar magnets in your world, do have a few ideas myself,

Kevin,

The BBC article is interesting but incomplete like most BBC articles. It said the dark matter is 10,000 degrees, degrees what? Kelvin I hope.

It seems to me something so hot would emit more radiation than zero.  If it is made up of WIMPs then it is possible but still unlikely. We will see.

Yeah, I didn't comment on that either, too confusing.


You are correct in that x-rays don't accurately trace the profiles of cluster cores, their inferred radius is smaller than suggested by earlier x-ray measurments.  This is not at odds with dark matter predictions, but creates complexities and discrepancies with cluster lensing, a method which seems to be playing the major role in detecting mass by gravity that also seems separate from the hot gas revealed by the x-ray observation that has differentiated the two. 

Evidence is strong that dark matter of some form exists from lensing and where it is, this is what makes these direct search experiments for dark matter particles important that Colin mentioned.  Don't know what it is, but it's out there, lensing narrows the search.

Is it dark matter in our own solar system, is it a misunderstanding of gravity at distance, or is it string theories mass in more than 3 dimensions exhibiting gravity in the three dimensions we can see? 

We are far from understanding what is going on in our local space. In my opinion scientist should be looking at all solutions, not just one.

The net buzz speculation gets really out there, many things to check for with the slight anomaly, instramentational included. 

Quote:
The measured deceleration is about one nanometer per second per second, measured over distances of about seven trillion meters.  That's twenty-one orders of magnitude between the length scales.  That's a thousand billion billion to one, a sextillion to uno,


Not sure if still tracked with budget cutbacks.

from a previous post:
Quote:
 The Cassini probe sent to Saturn tested general relativity with very accurate results.


But not exactly precise.  There was a decimal point with a few zeros after it.  Could be the next big net stink.  Things like that known, concern so far hasn't ruffled much.


Another good one is from the Russian Venera program, landing on Venus.  At a certain point of descent in its atmosphere all technical equipment blinks out for something like 5 seconds or longer.  I think we also experienced this with one atmospheric probe.


Quote:

It wouldn't help any with dark energy, 72% of the universe.  Doesn't happen in a gravity system, which trumps it.

Sorry I missed your peek oil question....

Peek oil is the point at which demand exceeds supply causing prices to sky rocket and loss of availability (as if prices weren't high enough already at £1.20 a liter($6.80 a gallon for our us friends))
A possible dooms day in it's self cos it will effect every thing.

sorry to go off topic . Maybe dark energy can be harnessed to overcome this problem.

Sort of ... peak oil occurs when the development of the resource hits a maximum and then begins to decline. There have been times in the past when demand exceeded supply, and that was not peak oil.

Peak oil will be a game-changer. Nothing out there will be able to economically replace oil. We won't run out of oil overnight, but the limited supply will drive the prices up, as you said.

Anytime in the past 50 years that the price of oil spiked, the economy went into a recession. Then demand decreased, and prices went down. I expect we'll see a lot of that in the next two decades ... every recovery will trigger an increase in oil prices, which will induce more economic malaise. The only way to get out of this is to move away from heavy dependency on a declining resource ... which may not be fun or easy.

No it won't and this is the basis of my original comment way up the page some where on funds for research into dark matter etc. maybe being better used else where such as research into renewable energy.

BTW I knew my spelling of peak didn't look right, duh ! Cheesy

Contact with Pioneer 11 was lost in 1995. Pioneer 10 was declared dead in 2003.

The anomaly wasn't net buzz, but straight from NASA. They discovered it and tried to get help finding the answer. I believe as of today it is still a mystery.

The budget cuts you are thinking about were for Voyager 1 and 2. Thankfully That didn't happen and both are still sending data.

Aware.  There was something about still tracking it with Doppler, not communication, that may have been cut off.



Quote:

There are a few to come across.  Smiley

Questioning general relativity and Newton's Law is always an option, as I mentioned concerning dark matter and may be going forward in some projects planned. 

Newton's laws of gravity are a limiting case within general relativity.  Maybe general relativity is imbedded in an even deeper theory of gravity, something missing from the right or left hand side of the equation.  Not easy, but yet only one aspect of a search.

Don't recall any question about peak oil.  ???   Just mentioned Arctic drilling and price, which doesn't have a relationship to the reserves in the Earth.


May 2007, M16 in Moscow and Beijing discovered Russia and China had signed an agreement to mine He-3 on the moon.  Both Roscosmos, Russia's Federal Space Agency, and China's Lunar Exploration agency predicted they would have a head start over rival NASA/ESA, who announced Moon bases by 2014.

Your landing sites and reactors will be based on remote moorlands in Scotland and the west of England, but less than secure defenses have been found from Russia and China.

After landing, processing, and fullfilling their domestic needs, and marketing globally at prices they set, M15/M16 computer experts at GCHQ predict cyberwarfare hacking from the pair will prevent us from completing the same.       spy vs spy stuff    Wink

Demand did usually go up in the summer - I remember 'the good old days' when people used to hop in the car and drive thousands of miles. That alone can raise prices, even if there was a perfect market (which we never had, too few companies with too much ability to reshape the market).

And refineries in many areas are required to change their formulation of gasoline with the seasons ... many areas are more likely to have thermal inversions in the summer, which traps pollution and leads to photochemical smog. To cut down on problems from pollution, the gasoline is required to burn cleaner at these times. It does add to the cost.

Sorry Kevin it wasn't so much a question as" not being aware of this doomsday"

I'm quoting from memory here couldn't figure out how to find Your post to copy the relevant part.

I think the oil companies are nothing short of devious especially when so many reports of people using water to run cars etc come out and then they are never herd of again

Urban legends. Yes, oil companies may be devious, but it is related to mundane things like trying to boost prices a few extra pennies, or covering up their pollution.

Water is not a limitless fuel - it is like ash, already oxidized and low energy. The only way to run a car on water is to split the water into hydrogen and oxygen, then burn those gases. It works, but you have to put more energy in than you get out.

If there is a miracle technology, it might be fusion. But fusion is 20 years in the future (and has been for the last 60 years).

Yes Jon, it has, but nonetheless an interesting sequence of articles from The New Scientist appearing sporadic over the years presently has intel services up on their toes about this for some reason, and concerned digesting the waves from a Russia/China agreement that seems to have been learned in 2007.  What are they up to, how large the repercussions.


Quote:
The Mine on the Moon

18 November 1995 by Justin Mullins

ONE day we will mine the Moon. We will mine it for a valuable fuel which will make fusion power possible at last. And that day will come soon: not in five hundred years' time but early the next century. Or so Hiromu Momota, professor of nuclear engineering at the National Institute of Fusion Science in Nagoya, believes. With access to the Moon's store of helium-3, a substance not found on Earth, he believes it will be possible to build fusion machines which are simpler, cheaper and cleaner. These machines could even be used to power spacecraft and generate high-energy beams to treat cancer.

The experimental fusion reactors now being built around the world ...



Then later, we have:

Quote:
China plans three-phase Moon exploration

03 March 2003 by Will Knight

China has revealed further details of its plans to explore the Moon...

...

Ziyuan said exploring the Moon "probably holds the key to humanity's future subsistence and development".

...

Furthermore, Luan Enjie, director of China National Space Administration, hinted that China would be interesting in exploiting rare resources found on the Moon's surface.

"The prospect for the development and utilisation of the lunar potential mineral and energy resources provide resource reserves for the sustainable development of human society," he told the newspaper.

However, James Oberg, a space analyst and veteran of the US space program, believes the projects are more about national pride than scientific or industrial exploration. Nonetheless, he says the lunar missions are well within China's means.

"They've already developed the capabilities to operate spacecraft around the Moon and even on its surface," he told New Scientist.

China has so far launched four "Shenzhou" spacecraft in preparation for a crewed mission into space. Such an achievement would make China only the third nation in the world, after the US and Russia, to place humans in space.

Oberg adds that China has set itself a number of ambitious goals. "As with their manned programme, they don't intend to recreate the US and Russian programmes," he says. "They intend to go to the head of the queue in terms of capabilities."



An announcement by Bush followed months later.

Quote:
Can we mine the Moon?

31 January 2004 by Eugenie Samuel Reich

The prospect of a permanent lunar base has certainly excited astronaut Harrison Schmitt, a veteran of the Apollo 17 mission. Nowadays Schmitt is a geologist at the University of Wisconsin in Madison and chairman of Interlune Intermars which raises money to develop lunar mining.

President Bush's announcement included references to the moon's "abundant resources", but Schmitt and his co-prospectors are primarily interested in one: helium-3. Helium deposits are scarce on Earth, and the isotope helium-3 is even rarer. Nevertheless, it is valuable in medical diagnostics, and researchers developing nuclear fusion reactors as a future solution to terrestrial power generation will use helium-3 by the bucket load. Soil samples brought back from Apollo suggest that the lunar surface, or regolith, contains vast amounts of helium and hydrogen deposited by the solar wind.

Astronomers have long known that in many surveys of the very distant Universe, a large fraction of the total intrinsic light was not being observed. Now, thanks to an extremely deep survey using two of the four giant 8.2-metre telescopes that make up ESO’s Very Large Telescope (VLT) and a unique custom-built filter, astronomers have determined that a large fraction of galaxies whose light took 10 billion years to reach us have gone undiscovered. The survey also helped uncover some of the faintest galaxies ever found at this early stage of the Universe.


I love how the first Blog says this can't possibly have anything to with dark matter. Finding matter we couldn't see before because of dust and gas means we still don't have all the answers to how much light emitting matter is out there.

Has Dark matter turned into a religion like AGW?
