RHIC Finds Symmetry Transformations In Quark Soup
eldavojohn writes "Today scientists at the Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory revealed new observations after creating a 'quark soup' that revealed hints of profound symmetry transformations when collisions create conditions in which temperatures reach four trillion degrees Celsius. A researcher explains the implications, 'RHIC's collisions of heavy nuclei at nearly light speed are designed to re-create, on a tiny scale, the conditions of the early universe. These new results thus suggest that RHIC may have a unique opportunity to test in the laboratory some crucial features of symmetry-altering bubbles speculated to have played important roles in the evolution of the infant universe.' These new findings hint at violations of mirror symmetry or parity by witnessing asymmetric charge separation in these collisions."
Delicious first post soup
Everyone knows that there is a slight asymmetry tending towards particles rather than anti-particles. It's common sense. It's the reason why the universe exists as matter rather thant antimatter.
Can I get a car analogy please?
Some left-handed scientist just discovered that when puoS krauQ is cut through, it turns out symmetrical.

That wily ferengi finally found some way to cook up Odo and serve him as a soup.
Yes but they do not know why, and research such as this may help reveal something about that.
We've known you need air to live for millenia and some short sighted folk back then probably said 'duh' too. Others tried to find out why. Now we know why. Are we better off not knowing?
The owner of the bar that was selling the soup denied there was anything wrong with it.
Any particle physicists out there who can tell (us) if this thing can make "strangelets"? I mean, I kinda buy the explanations of how the LHC won't make mini-black holes or if it does they will instantly "evaporate" but: 4 trillion degrees? Approximating the conditions not seen since the first billionth trillionth of a second (or something like that) of the big bang? And don't tell me that Nature regularly collides gold nuclei together in this fashion; they're not cosmic rays!
While we're at it, are "strangelets" (or strange matter) real, I mean are they a proven particle? (And if so, how did they prove their existence without supposedly creating any?) Anyway, if this thing does make (one) and the planet gets converted into a glob of it, hopefully it'll happen at the speed of light so we won't feel anything.
Also the phrase "symmetry-altering bubbles" when used in conjunction with the phrase "evolution of the infant UNIVERSE" makes me wonder just a little if they really want to be playing around with this stuff. At least I'm pretty sure that if a false vacuum bubble is created, it'll expand at the speed of light and we definitely won't feel a thing!
- I actually love science and physics and have full confidence in these guys. It's fun to be paranoid every now and then though.
I did that yesterday in my basement using a toaster, a bathtub, some aluminum foil, and a microwave.
"four trillion degrees Celsius"
When you're talking "trillions," there's really not much difference between degrees Celsius and kelvins. And all "four trillion degrees Celsius" means to the layman is "really fucking hot."
So... why not just "4 terakelvins?" Or is it exakelvins?
How come we can have an absolute cold, but not hot? 250,000 times hotter than the center of the sun doesn't sound too impressive considering that the sun isn't particularly hot as far as suns go. So what's the hottest where absolutely nothing can exist?
Einstein already suggested something like this, however he never did any research since the soup wasn't kosher.
And which one of you wanted the clean glass?

I really enjoy and believe in science. However... we're really playing with shit that we don't understand here; yeah, that's the nature of science, but this is different. Is "recreating conditions at the beginning of the universe" (yeah, I know it's somewhat of an analogy) on the only planet we have really the best idea?
I'm not saying it shouldn't be done, but have rational scientists even asked the question?

fcall me cynical, but it looks like a thin excuse for continued emploment
rom the article
"The discoveries at RHIC have led to compelling new questions in the field of quantum chromodynamics (QCD), the theory that describes the interactions of the smallest known components of the atomic nucleus. To probe these and other questions and conduct detailed studies of the plasma, Brookhaven physicists are planning to upgrade RHIC over the next few years to increase its collision rate and detector capabilities."
in other words, based on these prelimminary, not exactly repeated byothers, to be published (but they didn't say if it passed peer review) results,
GIVE US MORE MONEY
after all, its really important to know what happens at 4 trillion degrees.....
No soup for you!
Have gnu, will travel.
That's way too many Kevins!
But I guess it's better than having none at all.
My home town nearly went to zero Kevins back in 1978.
It was a particularly cold winter, and we were already down to 3 Kevins (due to their low popularity at the time).
Kevin Thomas had flown out to be with his son's family for a wedding and got stuck in Boston for a whole week due to the weather. 2 Kevins left.
Kevin Lemmer was rushed to the hospital during my shift. I still remember the call from the EMTs as the ambulance was rushing toward us. "It's Lemmer. He's in bad shape. Drove right into the fucking ditch." We called the time of death at 6:15 PM.
At 6:16, all eyes turned to room 2217. Kevin Spencer was 82 and on his death bed with leukemia. His family being Catholic, he had already been given his last writes. If he couldn't hold out until Kevin Thomas returned, we would be at zero Kevins. Sure, we had 4 perfectly healthy Calvins, but they're just not the same.
It was 7:15 when Carla Brooks and her husband James burst through the main entrance. "She's not due for 2 weeks!", James exclaimed. As the staff bustled around getting the Brookses settled, they exchanged darting glances with each other. This was their first child, and they wanted to keep the baby's sex a secret. Of course, in a small town, secrets don't get kept. Nearly all of the hospital staff new that the child about to rip open Mrs. Brooks was indeed a boy.
The delivery was routine, and Kevin Brooks was born healthy, if a tad underweight, at 10:52 PM. Kevin Spencer was pronounced dead at 10:54.
It was, as they say, a close one. Kevin Thomas arrived two days later, the weather having finally cleared up. To this day, we still rib him about it.
Cedar Falls is currently at 5 Kevins.
There is or there isn't a hair in my quantum soup!
Better to search for "quark-gluon plasma" if you are looking for more info on this subject.

How do we know other galaxies and stars are not anti-matter. It's not like we can touch them and find out.
Would it not be likely that thermal explosions could have sorted the two into far flung clumps in the early days of the universe.
Interactions might not be observed if all of the clumps are already flying away from each other.
Galaxies collide a lot. You'd expect at least one of the collisions which we can observe to be antimatter-matter, but it hasn't happened. And it would be REALLY easy to tell if it did.
Finally! A year of moderation! Ready for 2019?
That depends. Finding out why we need air to breathe didn't entail the possibility of ripping a hole in the space time continuum, with dire consequences for the solar system, the galaxy, and possibly the local universe. My money is on a certain percentage of Gamma Ray Bursters being the signature of an advancing civilization snuffing out its first really high energy particle accelerator, and its planet, and that the effects are localized to the vaporization of the planet or solar system. Since we're conducting our experiments on Earth, it's unlikely that I'll be able to collect, should any of you take up this bet.
If you mod me down, I shall become more powerful than you could possibly imagine.
The Higgs mechanism is often talked about as the source of mass, but what's less well publicised is that it's the dynamics of QCD (the strong interaction) that are responsible for the majority of the mass of ordinary matter, by a similar mechanism. Essentially, the vacuum isn't empty because the empty state isn't the lowest energy state - that requires a non-zero Higgs field and a non-zero quark condensate (from QCD).
The consequences of this are that particles behave as though they have mass when fundamentally they don't - they just behave that way because of their interactions with the background fields. If you excite the system to a high enough temperature though, there's a phase transition to the "free" state in a manner crudely analogous to boiling of a liquid releasing the confinement of adjacent molecules so they behave freely. In the QCD case, this temperature is low enough to be probed by experiments (not so much the electroweak/Higgs case), so we get free, low-mass quarks.
Energies at the Large Hadron Collider are likely to peak at 14 teraelectronvolts
breaks down at the quantum level. This energy is in the order of 1018 gigaelectronvolts
100 trillion times more energetic than the LHC
If I convert all those frighteningly big numbers to scientific notation, I get:
The parent is saying that the LHC puts out about 10x as much energy as that at which we lose all idea of what's happening. He's also saying that 1.02 e 12 is 100 trillion times 1.4 E 13. Something is not right here. Anyone care to set him/me/us straight?

I think it may be no so obvious... think of it, galaxies that collide are probably from the same local group, so that we don't see matter/anti-matter collisions shouldn't be strange.
I'll put a car analogy (in fact, the only reason of this post is to put the analogy): you are in Berlin a send a group of electric cars in a journey to Lisbon, and a group of diesel cars in a journey from Lisbon (and you go with them). Then you analize the crashes that happened in the journey, and since there are no signs of a collision of a electric car with a diesel car, you tell that all the cars were of the same type, and since yourself own a diesel car, you conclude that all cars were diesel.
Of course, not much of an scientific argument as a pointer to a logical weak point in your arguments...
Why can't
Not necessarily. Galactic collisions rarely involve actual collision of substantial amounts of mass. Most galactic collisions have the stars and other big objects never get anywhere near each other. The galaxies are deformed afterwords purely by gravitational effects. We can conclude from this that it is a) extremely unlikely for a chunk hypothesis and b) for anti-matter to have a repulsive gravitational effect on matter. But we've pretty close to completely ruled out b already.

Interactions might not be observed if all of the clumps are already flying away from each other.
The only way to tell matter from anti-matter at a distance is to observe their neutrino emissions. Anti-matter objects will preferentially emit neutrinos in the direction of spin of the baryons (the majority of which spin in the same direction as the containing object assuming a magnetic field.) while matter objects will emit them preferentially in the opposite direction.

thanks again sexconker, it was funny the first time :)
We can see galaxies from way back in time, there's no way we could miss it.
Finally! A year of moderation! Ready for 2019?
The gas/dust clouds would collide, even though few stars do. Detectable. And if even two stars did collide, the explosion would be unlike anything we've seen so far. Impossible to miss.
Finally! A year of moderation! Ready for 2019?
It took a lot of asking around, but someone finally pointed me the paper, which actually dates back to September.
Find free books.

Actually, anti-matter stars emit neutrinos while ordinary matter stars emit anti-neutrinos, so if you can tell them apart and where they came from, it would make things a lot easier.
