Visiting the Big Bang
DarkKnightRadick writes "An article at the NYTimes.com (Free reg) is reporting that researchers in Long Island, NY are attempting to create the quark-gluon plasma that existed a trillionth of a second after the big bang, when the universe was just the size of a marble or grapefruit. "Sam Aronson was perched a few stories up on a metal catwalk, surrounded by tons of Russian steel and Japanese electronics, and enough wires to impress even Con Ed, when he paused to say what really interested him about the $600 million machine. Time, he said. More precisely, the beginning of time, just after the Big Bang, some 14 billion years ago.""
Not trying to whore here, just being helpful:
I wonder how long before we can buy quark-gluon plasma tweeters
and what sort of frequency response we'll be getting.
Enjoy your Reg free link.

CERN has also been trying to produce a quark/gluon plasma (and may have already done it).
Googling only turns up articles of questionable use. You can find better information in their list of experiments, and maybe a summary elsewhere on the CERN web site.
It's always nice to see this continuing story make it to the mainstream media from time to time.
I wouldn't be opposed to something like a half hour or hour special, really.
But every now and then if I watch my local neighborhood college channel, they have this old MIT physics lecture series which coincidently featers one of the researchers involved with this. The last lecture of the series, he talks a lot about the project, as a send off to his students. My college professors were rarely so engaging.
I can't help but be in awe of the incredible might of our intellect. That the minds of men were are able to fling heavy nuclei together bringing the temperature of a little pocket of space to two trillion degrees (at temperatures that great units are almost irrelivant, but K), pushing the hands of time back, esentially, to the moment of our universe's conception, is why we have words like 'brilliant', 'awesome', and 'incredible'.
That I should be fortunate enough to live in a society that permits an average Joe, such as myself, to understand the mechanics of such a feat in qualitative terms, even if the quantitative methodes elude me, is truly a blessing. That a majority of my people seem to think creationism should be taught in schools, tells me too few of my countrymen take advantage of it.

A freak accident in the laboratory led to the spill of this quark-gluon plasma on an unfortunate researcher, turning him into...
Quark-Gluon Man!
Faster than a speeding universal boundary
More powerful than a supernova
Able to create dimensions within a single bound

Some fun stuff - the detectors (stories tall)are essentially front ends to circuits that need to sort and detect events happening at a significant fraction of c, discriminate between crap (eg cosmic ray events and glancing hits) and what they were aiming for (collisions).
"The next round of RHIC experiments will have larger data volumes per event and
larger event rates... in each case, about an order of magnitude greater than the present
values. This is similar to the environment faced by the LHC ALICE detector. As a base
model, it is assumed that the upgraded RHIC detectors will record ~1MB/event; the
Level-0 triggers will accept events at a rate of 25 KHz; and that data can be archived at a
rate of 250 MB/sec."
So you before you can say not much remember these are circuits weighing tons a hundred+ feet tall that need to be synchronised with the collisions in the beam, amazingly reliable and put up with a large amount of abuse (hard radiation when it leaks from the guts of the device).

Such funding would be alot better spent toward the envestment to a pure hydrogen energy economy. Hell, just half of that would really help out in Fusion research.
....such as the dwendling of a limited resource of oil.
I'm all for science. But damn, let's try and be just a 'tiny' bit more productive with the issues at hand.
BTW, I'm not an enviromentalist. I'm just being realistic.
It has long been known that the fabric of space-time is curved. The passage of time is more than merely curved - it is, in fact, circular. The so-called "beginning" of the universe, commonly known as the big bang, occurs every 14 billion years, an instant after some guy flips the switch on a quark-gluon plasma generator, thus ripping the universe apart in it's own creation. Although this is known, any attempts to stop the guy before he starts the generator have been deemed as a pointless waste of whatever time we have left, seeing as we obviously didn't manage it last time.
According to the most current theories (AFAIK), the universe begain expanding at around the speed of light. Then, for unknown reasons, it began it's "inflationary" period, where space expanded faster than the speed of light. After a while, back to normal inflation.
The "inflationary" model was sort of a hack to make the theory agree with the observations. No actual reason for what starts it has been proposed AFAIK.
Who is to say that we might not accidentally create a sort of "mini-inflation" at one of these accelerators, thereby destroying the Earth, the Solar System, or even more. Nobody knows what triggered inflation. What if we do it accidentaly?
I know that this idea sounds absurd. It probably even IS absurd. But ... do we really know? Remember - the Relativity was considered by most to be absurd when it first appeared.
"-1 Troll" is the apparently the same as "-1 I disagree with you."
Schild's Ladder is a much better story than your inane post.
"The "inflationary" model was sort of a hack to make the theory agree with the observations. No actual reason for what starts it has been proposed AFAIK."
Yes, you are right about the hack part, but inflationary theory explains why our universe has an omega so close to 1 and why apparently disconnected parts of the cosmic microwave background have similiar temperatures. As for the reason it starts, well, there are plenty of ideas, but none of them easily testable (and I can't remember what they were, but they were all very high energy fields breaking indegeneracy...anyone care to comment?).
Alan Guth wrote a book called "The Inflationary Universe" (admittedly he came up with the idea) which gives a very clear explanation why inflation theory seems more suited than many other alternate theories.
"Who is to say that we might not accidentally create a sort of "mini-inflation" at one of these accelerators, thereby destroying the Earth, the Solar System, or even more. Nobody knows what triggered inflation. What if we do it accidentaly?"
A good question, and it was considered seriously by Martin Rees, a famous astrophysicist now at Cambridge. He did calculations showing that cosmic rays many thousands of times more energetic than the best we can do with earthly accelerators routinely hit our upper atmosphere. Given that billions of years of cosmic ray bombardment have not triggred a new universe type of scenario, it is probably safe to say that our experiments won't trigger one off.
I'm keeping my fingers crossed!

With colliding gold nuclei. Jeez, didn't those people read Cosm!? When they start working with uranium, I'm staying the hell out of New England.
Life is like surrealism: if you have to have it explained to you, you can't afford it.

I went down there, right up to the gate of BNL and requested a visit. The guards denyed entry, but after a bit of whining and .5 hr wait, got me a German scientist in a little car to show me around.
:)
Good to see security was tighter than SUNY Stonybrook. I remember walking into their radiation area without a hinderance, badging myself a radiation detector and taking a tour among the huge tanks, and old books on fission and fusion...
Anyway, in BNL, the guy took me to the Star detector area, and we met a Russian scientist who showed me the data capture machinery. The detector is connected with 10,000s of yellow ethernet-like wires in very thick bundles and entering an area where rows over rows of shelves contained custimzed cards where the cables ended. Looked MASSIVELY parallel. I think the cards (size of 1u server each) had buffers to hold the data, that then got serially taken away and compressed into ANOTHER building that did nothing but crunch data. Sadly that computer building was closed.
Later we went to his office in the theory department. There are several theoretical groups from 5 ppl to sometimes over 100. They join their heads against specific problems and the whole thing results in boring papers. But this guy had Linux on a nice VaLinux machine, running X and I think WordPerfect, and lots of proprietary apps. Oh yeah I saw Mathematica. They all know that app.
Working on now to get qualifications to be able to work there. Ive always hated corporate life.

Good book so far; I'm in the middle of it.
But I am somewhat concerned that physicists might do something that could do things you guys are describing. I have no particular concerns, as i don't have the physics, but I think that in some ways it was unforgivable that we tested the atom bomb when there was believed to be the slim possibility of igniting our atmosphere in a self-sustaining reaction.
I'm reminded of the Fermii Paradox...may it be that the brightest of our minds do us in with their curiosity?
Logic, macros, and more
"We don't know where it is, no one can detect it, and we haven't the slightest clue about what it is in the first place, but it must be there because the models say so." Right.
This guy is very confused, but his post is not flamebait. Moderators shouldn't moderate people down just for being creationists. It denies the rest of us the opportunity to see them get a good bitch slapping by a biologist who's got his threshold set to +2.
The purpose of science class is not to dispense Ultimate Truth. It is to teach the scientific method, and make students familiar with the body of scientific knowledge as currently understood by mainstream science. Our current theories of gravity are wrong. And we know they're wrong. Does this mean that students shouldn't be taught about gravity? We teach kids Newton's Law of Gravitation and we know for a fact that it's wrong. High schools teach kids the Bohr model of the atom, which is also known to be wrong. I never hear creationists complain about either- probably because Genesis is silent on the subject.
We don't have a satisfactory theory of gravity. That things fall is fact and should be taught as fact. We may not have a complete theory of evolution. This is mostly due to spotty evidence, which is par for the course (fossils are rare). But unlike gravity, our theories of biological evolution are consistent with all of the evidence we've managed to find. That evolution occurs in some form cannot be denied with a straight face, and it should be taught as fact just like anything else is, once our certainty has risen above a certain threshold that is close to 100%. We don't have a continuous surveillance videotape of every biological event that has occurred in the past 12 billion years, but this is a ridiculous thing to ask for.
Maybe the facts we teach might someday turn out to be wrong as new evidence is uncovered. So what? This has never bothered us before in any other scientific field. The secular world makes no claims of infalliblity. Ultimate Truth is not always attainable by humans, and to insist that everything taught in science must be verified to be absolute fact before it can be taught in the classroom is nonsensical. A silly policy like that would put an end to technological and scientific progress within a generation.
Also note that when this type of matter existed, all the matter in the universe existed in this form and was compressed almost infinitely to a very small size. In this experiment a very small (insignificant) ammount of matter will be created. No harm done, right?
I would far prefer that the human race be destroyed accidently in the pursuit of knowledge, than oh say, by WWIII, or by terrorists unleashing a virus, or some other Bush inspired action. The end result may be mostly the same, but at least the pusuit of knowledge has just a little more dignity. It's a debate whether dying of hubris or dying of stupidity is better. I vote hubris.
1) If all the mass of the universe (!), every galaxy, star, planet, shipyard, three-bedroom apartment and breadmaker, once occupied the space of a walnut, wouldn't that be a super-duper-duper massive black hole? How did all the stuff get out?
2) Assuming the stuff did get out (since I'm writing this), wouldn't the light from that explosion have preceded the material? In other words, we can't look "back" at something that already happened, since we would have to have traveled FTL to do this. And, ATAE and GR, we can't do FTL. (Just imagine trying to pick up radio broadcasts from the 1920's. We'd have to travel in an FTL spaceship to a point just outside the 80-some lightyear radius bubble of that wavefront.)
This is not to say that I believe creationism any better, but that I am a skeptic of most theories.
