Early Universe was a liquid: First results from the Large Hadron Collider's ALICE experiment
Real lead-lead collision in ALICE
(PhysOrg.com) -- In an experiment to collide lead nuclei together at CERN's Large Hadron Collider physicists from the ALICE detector team including researchers from the University of Birmingham have discovered that the very early Universe was not only very hot and dense but behaved like a hot liquid.
By accelerating and smashing together lead nuclei at the highest possible energies, the ALICE experiment has generated incredibly hot and dense sub-atomic fireballs, recreating the conditions that existed in the first few microseconds after the Big Bang. Scientists claim that these mini big bangs create temperatures of over ten trillion degrees.
At these temperatures normal matter is expected to melt into an exotic, primordial soup known as quark-gluon plasma. These first results from lead collisions have already ruled out a number of theoretical physics models, including ones predicting that the quark-gluon plasma created at these energies would behave like a gas.
Although previous research in the USA at lower energies, indicated that the hot fire balls produced in nuclei collisions behaved like a liquid, many expected the quark-gluon plasma to behave like a gas at these much higher energies.
Scientists from the University of Birminghams School of Physics and Astronomy are playing a key role in this new phase of the LHCs programme which comes after seven months of successfully colliding protons at high energies. Dr David Evans, from the University of Birminghams School of Physics and Astronomy, and UK lead investigator at ALICE experiment, said: Although it is very early days we are already learning more about the early Universe.
He continues: These first results would seem to suggest that the Universe would have behaved like a super-hot liquid immediately after the Big Bang.
The team has also discovered that more sub-atomic particles are produced in these head-on collisions than some theoretical models previously suggested. The fireballs resulting from the collision only lasts a short time, but when the soup cools down, the researchers are able to see thousands of particles radiating out from the fireball. It is in this debris that they are able to draw conclusions about the soups behaviour.
The ALICE Experiment
Physicists working on the ALICE experiment will study the properties, still largely unknown, of the state of matter called a quark-gluon plasma. This will help them understand more about the strong force and how it governs matter; the nature of the confinement of quarks why quarks are confined in matter, such as protons; and how the Strong Force generates 98% of the mass of protons and neutrons. The ALICE detector is placed in the LHC ring, some 300 feet (100 metres) underground, is 52 feet (16 metres) high, 85 feet (26 metres) long and weighs about 10,000 tons.
The ALICE Collaboration consists of around 1000 physicists and engineers from about 100 institutes in 30 countries. The UK group consists of eight physicists and engineers and seven PhD students from the University of Birmingham. It plays a vital role in the design and construction of the central trigger electronics (the ALICE Brain) and corresponding software. In addition, the UK group is making an important contribution to the analysis of ALICE data.
During collisions of lead nuclei, ALICE will record data to disk at a rate of 1.2 GBytes (two CDs) every second and will write over two PBytes (two million GBytes) of data to disk; this is equivalent to more than three million CDs (or a stack of CDs (without boxes) several miles high). To process these data, ALICE will need 50,000 top-of-the-range PCs, from all over the world, running 24 hours a day.
ALICE utilises state-of-the-art technology including high precision systems for the detection and tracking of subatomic particles, ultra-miniaturised systems for the processing of electronic signals, and a worldwide distribution network of the computing resources for data analysis (the GRID). Many of these technological developments have direct implications to everyday life such as medical imaging, microelectronics and information technology.

It is acmirable that the two of you express concern over the "waste" of these funds spent in pursuit of understanding the fundamental principles of the universe.
This research, and, in fact, virtually all hard scientific research, will produce benefits for the public at large, if not now, then later. Attacking this spending is like attacking the funding of NASA -which attack you may(I don't know one way or the other) actually support- with an equally specious argument.
If you want to attack waste, why aren't you decrying the BILLIONS of dollars awarded to CEOs/ CFOs, hedge-fund managers, and commodities-market cornerers? The efforts of these people have a direct, negative impact in the lives of the people as an unquestioned, unmitigated consequence of funneling wealth into the hands of a TINY MINORITY of people at the expense of everyone else's quality(or lack thereof) of life.

Well, Ahhzzee, let's examine this question, and allow me to illuminate the issue by asking a question of my own: do you have any credit cards, loans, or a mortgage? Do you have any investments? Do you own any insurance products? Do you eat food, or wear clothes, or consume any other products that you don't, yourself, personally produce?
I thought so. You would like to think that you have control over who you pay for what, but the hard truth is that you, like 95% of the rest of Americans, pay for everything you consume, and have exactly no say over pricing or distribution of those products, and the actions of the co. officers, in your mind, are above reproach, even when those people are paid(and bonused) to deliberately defraud both the

And when their rapacious greed and its only too-predictable consequences led directly to the collapse of the economy, who picks up the tab -and I don't mean only in terms of bailouts- I mean also in savings to those same companies through downsizing, offshoring, restructuring, and layoffs.
So, yes, you should have a problem with how that money is spent- because it cost you(whether you realize it not), at least indirectly, and if not you yourself, then someone you know was affected directly when they lost their job, or home, or their retirement investments, and everyone, everytime we buy a loaf of bread, or a gallon of milk, to the tune of trillions of dollars on an ongoing basis.
At least ALICE holds the promise of almost certainly providing some benefit in the near future. Those whose spending habits you hold so near and dear make no promise except the implicit one of bleeding us out until no more blood will come, and then tossing aside the husk.

I somehow wonder how the big bang started in the first place. Out of nothing? But we know that nothing comes from nothing. You cannot have something come from nothing, that's impossible. If you insist that the big bang started from a singularity you've got the huge problem of explaining how it got OUT of that singularity in the first place since it's a thermodynamic dead end. Also if something existed before the big bang then another mystery needs to be explained.
Hence the big bang is another myth - with just as loud and devout religious followers as the other religions.
Then: information from nothing? All our current knowledge indicates that information does not come from random physical processes, only from an intelligent source[if you disagree please let us know of your non-intelligent information source].
Hence if you insist that the universe is information there must have been an intelligence behind it.

Please, let that post be from a troll. Please. Statements such as "just a theory" and "it will never be solved because no one was there" have been refuted ad infinitum ad nauseum. How can there still be such ignorant people?
Sigh...first of all the definition of the word "theory" in science is not the same as the common definition. The common meaning of "theory" is hypothesis. That is the way this person has incorrectly used it. Also, the use of the word "just" preceding "theory" is incorrect as there is nothing "just" or "only" or "mere" about it.

Regarding the statement that "it will never be solved because no one was there", that is severely flawed reasoning I am certain is obvious to most. He is claiming it is incorrect for a person to conclude something to be true that they have not observed directly themselves. He has no concept of what evidence is. To be consistent, not only would someone have to have "been there" but *you& would have to have been there since there is no way for you to know that someone was there if you ignore evidence. Reasoning and critical thinking skills desperately need to be taught in schools.

I'm an atheist and as big a supporter of the scientific method as anybody. But it is the height of hubris to think that, with our still-very primitive knowledge and technology, we know how to calculate the "net energy balance of the universe". We don't even know what the universe itself is yet, nor time, nor life.
An astronomer said a long time ago that "Not only is the universe stranger than we imagine, it is stranger than we can imagine." Nothing much has changed. Everyday we learn something weirder than we thought possible just yesterday.
Our puny brains cannot evolve fast enough to process the exponential growth of knowledge. My favorite statistic of all time is that 99.99% of all the scientists that have ever lived in the entire history of the human race - are still alive. And what we will be able to do in 100 years will be indistinguishable from magic today.

We accept that the big four - EMF , SNF, WNF, and G are all present today. and that big T was a concequence of the BB. But we do not accept that the big four were present at the BB. Take EMF - isin't it speculated that this force possibly split off from G during the cool down. We cannot create an experiment that mimicks the BB if we cannot resolve the experiment to within the confines of the forces that were present at the time. Everything derived from such effort is flawed. Garbage in .. garbage out.

It's not commonly recognized that big projects like the moon landing or LHC are just culmination points in technology, tips of icebergs that become visible when the technology is already there or someone has a very good idea on how to do it, so they can be built. With too much "unobtanium" in the mix, these projects would never get off the drawing board.
The most expensive part then is putting it all together and then watching 50 billion dollars of taxpayers' money fly into the moon, or bang lead atoms together.
That means the project itself doesn't generate anything useful per se in terms of offshoot technology, because that technology already existed. People think it's because of the big science project that it exists, when it was only popularized by it and used to justify it post-hoc.

He says that because the other galaxies would be too far away for future inhabitants to see, they would make all the wrong assumptions about how the universe began and what it is. Again, we are just in that perfect time to be able to figure everything out. What a lucky freakin' coincidence. But if he is wrong about our time, he is also wrong about everything else, by his own logic.

"All space is filled with equally dense material. Gold fills only a small fraction of the space assigned to it, and yet has a big mass. How much greater must be the total mass filling that space?"
[Robert Hooke, 1687]
Hooke is known as being deeply inspired with Oriental knowledge, for example his law of celestial gravity, which motivated Newton's law of gravitation is probably based on Ibn Rushd's geocentric model and Al Kindi's 9th century law of terrestrial gravity, which may be based upon the ideas of Greek philosophers, etc...

The global aerosol contraceptive is an interesting concept but how would you control or limit it to 70% effectiveness? And why 70%?
Our species is nearing plague proportions and there is no indication that our explosive population growth will decline.
Perhaps we have to breed ourselves to a level where we are unable to feed ourselves.
Aerosol contraceptives aside, we do need to look at ways of reducing the planets population.
Physics will not give us that but perhaps some new line of research will.
So let us encourage ALL lines of research, for in research lies our only hope of any extended future.

Youre not even a very good writer. Your thoughts are rambling, confused, manic. And youre obviously having no effect other than to alienate others who were encouraging you initially, but now sense your unbalanced state, and so are withdrawing. As Im sure you have from most of society.
It always happens this way doesnt it dick? You make friends and then lose them, and its THEIR FAULT every time, isnt it? Never yours, right? You hate them all dont you? Dont you dick?
Do you sweat when you type? Or do you just sweat all the time?
Here is some pleasant music to calm your fevered brow:

"Before Chaucer was dead the study of Greek, almost forgotten in Western Europe during the Middle Ages, had been renewed in Italy, and it received a still further impulse when at the taking of Constantinople by the Turks in 1453 Greek scholars and manuscripts were scattered to the West."

Did not the Irish keep (as per my middle school teacher) THE FLAME OF LEARNING ALIVE as the rest of Europe sunk into the dark ages. (They were not as dark as may be supposed, but certainly a lot of learning stopped.
