The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is a world-class scientific research facility that began operation in 2000, following 10 years of development and construction. Hundreds of physicists from around the world use RHIC to study what the universe may have looked like in the first few moments after its creation. RHIC drives two intersecting beams of gold ions head-on, in a subatomic collision. What physicists learn from these collisions may help us understand more about why the physical world works the way it does, from the smallest subatomic particles, to the largest stars
Well I have to deal with first things first here. This article above correlates the one given by Stefan. This is not to contest what you are saying, just to show you the informtaion I myself had gone through to arrive at the conclusions I do.
Ion-Smashing Yields New Knowledge, But Some Still Question Risk
By Carolyn Weaver
Seen from above, the Relativistic Heavy Ion Collider, or RHIC, at New York’s Brookhaven National Laboratory, looks like a racetrack. And it is a kind of race track: two “beam pipes” in a tunnel nearly four kilometers around, in which gold nuclei are accelerated to close to the speed of light, and are crashed into each other at intersecting points along the way. Out of the kinetic energy of those collisions, new matter is created for a brief instant: a shower of quarks and gluons, the smallest particles known – and at seven trillion degrees, hotter than anything now in the universe.
Brookhaven physicist Peter Steinberg
“It’s basically a living embodiment of E=mc squared,” says Brookhaven physicist Peter Steinberg. “Einstein’s theory told us a hundred years ago that you can trade off energy for mass, and vice versa. We’re essentially converting the kinetic energy, the energy from the motion of these nuclei, converting it into lots of particles.”
The four detectors that bestride the collision points are massive machines, with “time projection chambers” that record the collisions and their after-moments. The latest results made big news last year when Brookhaven physicists reported that the quark-gluon plasma was not a gas as expected, but rather a very dense liquid.
You say strangelets do not exist? And that no connection has been found between string theory, and strangelets. I have to then argue my case so you see it in light of what the reductionistic physics is actually doing, while string theory and it’s energy values hover overhead of all these interactions. How th epaticle inclination must also include microstate blackhole creation.
So bear with me if you can.
strange matter and strangelets are a very interesting topic, but, unfortunately, there has been no experimental evidence for them so far. They are not really connected to string theory either, besides the fact that it was an early paper of Witten that resuscitated interest in them with nuclear physicists, I think.
Strangelets have been thought of as possible culprits for RHIC disaster scenarios (besides the ubiquitous black holes ;-), and as responsible for potential cosmic ray particles beyond the GZK cutoff.
But as far as I know, there has been no experimental verification of any of these ideas (and the world still exists: RHIC has produced no greedy strangelets which would have eaten up the Earth).
In the case of the potential quark star you cite, RX J185635-375, again, and unfortunately, as far as I remember, it came out that the radius determination was not completely safe. Bottomline was that this star could be well understood as a common neutron star. I am not completely sure, though, about the current status of this object, whether it is thought to be a quark star or not.
Anyway, it is a good example for an exciting observation which is reported in the press, but which has to be partially revisd later – only that these revisions don’t make in the press releases. I guess it would often be quite interesting to have a kind of follow-up reporting, where one could read what is, eventually, the fate of some discovery that has been announced in the press.
The strange particles I was talking about are not strangelets, but the common hadrons with strangeness, especially the Ξs and the Ωs, with two and three strange quarks, respectively. These are the particles that I had mentioned in my earlier post, and whereof I should finish the second part, finally ;-). You typically find much more of these particles in nucleus-nucleus collisions than in (properly scaled) nucleon-nucleus collisions, which is a strong indication for an intermediate QGP state, where stange-antistrang quark pairs can easily be produced.
One, as we know can make wide sweeping generalization about the physics and why is it that any position taken by any scientist would not have been one that becomes the point of departure for all scientists? An example her ei the rationship to the Heavy Ion collsions an dstringtheory and by this very nature to the strangelets as postulated.
This article below is to correlate with the article you showed me of 2004, while I had made this ocnlusion myself early in 2006, lets not forget the number of people involved in the “ghost particle, and Pauli” through out the years and what we have seen theoretically of the strangelets as they had been related to the disaster scenario as consequential microstate blackholes created in the RHIC and LHC.
Is this too drastic a scenario to have you think about what all these “particles in press” are saying about the science, that any one scientist themselves might be following to correct? You say, “just get it right?” Well there are many within the blogs who are writers for those articles? Why do you think they are amongst you?
I had noticed the grouping and conversations between blogs that had been developing over the last year and half. I continue to see some of the same people. Some, that constantly referred to the reporting that goes on. So I had to address this or forever be banished to the realm of reporting as someone just profiled.
Strangelet Search at RHIC by STAR Collaboration
Three models of strangelet production in high-energy heavy-ion collisions have been proposed in the 1980s and 1990s: coalescence , thermal statistical production , and distillation from a Quark Gluon Plasma (QGP) [12, 13]. The first two models usually predict low strangelet production cross sections at mid-rapidity, as verified by measurements of the related processes of coalescence of nucleons into nuclei . If a QGP is created in heavy ion collisions, it could cool down by distillation (kaon emission) and condense to strange-quark-rich matter in its ground state – a strangelet. However, this requires a net baryon excess and a non-explosive process in the collisions [12, 15]. Neither of these conditions is
favored at mid-rapidity in ultra-high energy heavy ion collisions, as suggested by results from the Relativistic Heavy Ion Collider (RHIC) at BNL . Recently a new mechanism for strangelet
I want you to have a good look at the number of names listed in this Pdf file as well the universities involve.
Clifford of Asymptotia made this point clear about the vast network of scientists even within the string theory network of people and about who knows whom? Can you possibly know everyone, or, like the paper whose citations are referred to more as we refer to any particular scientist? We then come to see the make up and nature as we hold our views to the particular few.
So before I begin here I wanted to make it clear, that having spent considerable time as hobby and interest about science. It is not without my own motivations that the interest would be the memory of one’s childhood, or the magazine that we looked at, but the reality we are dealing with and what we call the “nature of things.”
An anomaly that cannot be explained nor shall it be removed because of the lack of evidence. It’s just one of those things that you cannot change in the person’s make up who has seen the world in a different way then normal. So shall he endeavor to accumulate all the things that are wrong to destabilization the view of truth of the world just so he can corrupt all those around him?
I ask myself the question about “what is natural” because I seen what scientists were doing to each other about the theoretical/concepts/ideas models that they were adopting in their research, that I wanted to make sure that what I had been researching had been as up to date.
Would one “leave out information that I had assembled” as they deal with me?
As I have said before while the students have been engaged in the classroom I had been following the physics development as best I could. Spent years watching and learning
So here’s the thing.
If I did not answer Stefan at Backreaction about the information about strangelets then it might have been left off where Stefan decided too as he continues to show his elementary particle thinking( finish the second part Stefan).
Continued reference to strangelets might everyone think the conclusion as written I the way Stefan has shown it? Would information I had been developing have been less than the standard of what scientists hold as standard. How could anyone know it all? Hold the badge over the trial of LHC or RHIC and say I had broken the law with my insolence and corruptible behavior?:) Non! Qui?
So here again is the conundrum I had placed in front of me as I looked and interacted with the various blogs who have commented on Lee Smolin’s book, “The trouble With Physics.”
But first let me then deal with Stefan at Backreaction.
Well, I think that even if someone believes that theoretical physics can’t be trusted – and many people clearly do – there exists a less scientific argument why the accelerator won’t lead to such a catastrophe: the Earth is bombed by a lot of very high-energy cosmic rays and the center-of-mass energy of the collisions is comparable to the LHC energies. So far, these collisions haven’t destroyed the Earth, so it is reasonable that some additional collisions we create won’t be able to do so either.
While I had these similar thoughts it was not wothpt some basis the Blogett would have pointe dyou to think about strnagelets and then in my own assumptions, the comic particle collsions from what Ellis had taught us to think about. Yes, it was the natural collider in space for sure, and it’s “energy values” well beyond what is availiable at LHC.
So yes “Microstate creation of blackholes in space”
In strangelets do not exist, I had come to the same conclusion Stefan did about what is “theoretically challenged” might have engaged the thinking mind as to the relationship to what the neutrino may have been in that exercise of the QGP, compared to this one on strangelets.
So I gathered information to help me see the direction the physics was going. Least it escaped the mantra that I had been hearing exemplified in my dealings as best I can.
“Lead by the Physics.” Now I face, “the trouble with Physics.”
