1.9.2008. // Labin.com // Objavljeno u kategoriji Znanost i tehnologija
U CERN-u (Europski centar za nuklearna istraživanja) u blizini Ženeve odbrojavaju se posljednji dani prije početka jednog od najskupljih i intelektualno najzahtjevnijih znanstvenih pothvata u povijesti.
Naime, 10. rujna službeno je označen kao datum početka rada LHC-a (Large Hadron Collider), golemog akceleratora smještenog u tunelu opsega 27 kilometara na dubini od 100 metara. Glavni cilj oko pet milijardi eura vrijednog projekta LHC-a jest uloviti Higgsov bozon, hipotetsku česticu koja je ključ za razumijavanje mase.

Suffering Extreme Anxiety Because of LHC in CERN - Please Help
Raste (Anxiety) anksioznost (i zabrinutost) zbog rizika u pokusu! Some scientists are very concerned!
LHC Safety Refuted by German Astrophysicist Dr. Rainer Plaga who concludes in his August 10, 2008 paper “ exclusion of dangerous mBHs thus remains not definite.” and “ there is a definite risk from mBHs production at colliders. A nightmarish situation, that can still be hoped to be averted in time through communication within the scientific community, is drawn attention to.
The Potential for Danger in Particle Collider Experiments | The ...
But only if the experiment becomes overcritical before a scientific consensus has been achieved (our current situation unless a miracle happens). Or else after it has been done with the dreaded outcome so that the catastrophe takes its course.
Concerns have been raised about the safety of the LHC on the grounds that high-energy particle collisions performed in the collider might cause disastrous events, including the production of stable micro black holes (mBHs) and strangelets . [9] [10] Several CERN-commissioned reports [11] [12] [13] [14] [15] and subsequently published research papers [16] [17] have corroborated the safety of the LHC particle collisions.
In the past I have had suffered from large amounts of anxiety due to my questions about death, purpose of life, religious matters, and more recently science. I have managed to temporarily calm my fear of death, but that fear has been replaced with an intense fear of certain scientific matters, specific astronomy and extremely advanced areas of physics (such as what is being done as LHC).
To give you an example of my thinking, I have an unquenchable thirst for knowledge. I often spend hours at a time reading Wikipedia. In college after my classwork was done, I would spend hours reading random books I found in the University library about every topic until the library closed. History, business, science, religion, philosophy, etc. Reading about astronomy, and outer space in general, and my mind's insistence on trying to comprehend these things in their full capacity, has led me to become absolutely terrified of reading about outer space or even looking at the stars. I only go out at night when it is cloudy, or if I must go out when the stars are out, I put my sun visor down (yes, at night) to keep from seeing the stars. Everytime I look at them I keep trying to grasp my mind around the incredible proportions in which stars exist. To think I'm looking at something so far away, it took the light itself years to reach me is literally mind bending and induces an incredible amount of anxiety on me. Or trying to comprehend the power of a supernova or a black hole. Impossible given the limited comprehension our minds have. But my brain insists on trying, which most of the time makes me feel disconnected from reality and out of touch with human emotion and engulfed in anxiety.
But I've managed to calm my fears of the stars recently, at least to a livable extent, although I still hide from them.
More recently I have read about LHC and it's potential to do harm. I understand that thousands of the world's best physicists are working on this project. However I feel as though we are entering a era in science where we are running too far into the unknown without first taking due caution. The blind and unquenchable thirst for discovery by scientists has made safety and respect for mother nature take a back seat. Safety of particle collisions
Main article: Safety of the Large Hadron Collider
Concerns have been raised regarding the safety of the Large Hadron Collider (LHC) on the grounds that high-energy particle collisions performed in the LHC might produce dangerous phenomena, including micro black holes, strangelets, vacuum bubbles and magnetic monopoles.[9][10][28][29]
In response to these concerns, the LHC Safety Study Group, a group of independent scientists, performed a safety analysis of the LHC and concluded in a report published in 2003 that there is "no basis for any conceivable threat".[12] In 2008, drawing from new experimental data and theoretical understanding, the LHC Safety Assessment Group (LSAG) published a report updating the 2003 safety review, in which they reaffirmed and extended its conclusions that LHC particle collisions present no danger.[11][13][14][15] The LSAG report was reviewed and endorsed by CERN’s Scientific Policy Committee (SPC),[30] a group of external scientists that advises CERN’s governing body, its Council.[11]
Two subsequent research papers have corroborated the safety of the LHC particle collisions.[31][17] In an article posted on the web on August 10, 2008, one researcher concluded that "at the present stage of knowledge there is a definite risk from mBHs production at colliders."[18]
On 21 March, 2008, a complaint requesting an injunction to halt the LHC's startup was filed by a group of seven concerned individuals against CERN and its American collaborators, the US Department of Energy, the National Science Foundation and the Fermi National Accelerator Laboratory, before the United States District Court for the District of Hawaii.[9][32] Following the publication of the LSAG report,[13] the US Government called for summary dismissal of the suit against the government defendants.[33]
On August 26, 2008, suit was filed against CERN in the European Court of Human Rights in Strasbourg alleging the Large Hadron Collider poses grave risks for the safety of the 20 member states of the European Union and their citizens.[34][35]
On the second front, I predict explicit new attention to the problem of redirecting funds from toll access to open access (TA to OA). For journals, as opposed to repositories, this is the endgame. The most ambitious current initiative is the CERN project to convert all the TA journals in particle physics to OA. Publishers are fully involved and cooperating, and see the plan as something closer to risk management than risk amplification. If the CERN project succeeds, and I predict that it will, then it will trigger creative and constructive conversations about how to do the same in other fields --convert journals, keep paying their expenses, save money, remove access barriers for everyone, and see the beginning of the end of the transition to OA.
Citizens Against The Large Hadron Collider is a non-profit organization
established for the purpose of using legal action to prevent the operation
of the Large Hadron Collider (LHC) until further safety tests are conducted.
The LHC is a particle accelerator located on the France/Switzerland border;
it has been dubbed the largest, most expensive, most powerful experiment
ever attempted, certainly dwarfing all particle colliders ever built before,
both in terms of size and power.
Some experts fear that the risk of operating the LHC disproportionately
outweighs anything science might gain from this experiment. It is not
possible to know what the outcome of the experiment will be, but even CERN
(the European Organization for Nuclear Research) scientists concede that there is a real possibility of creating destructive theoretical anomalies such as miniature black holes, strangelets and deSitter space transitions.
These events have the potential to fundamentally alter matter and destroy
our planet.
OA advocates have always argued that funding OA doesn't require new money, just a redirection of the money now spent on subscriptions. We see small new pressures for redirection every time libraries cancel journals because of high prices or inadequate funds, and we see small actual steps toward redirection every time a TA journal converts to OA. What's most significant about the CERN project is that it's a large-scale, discipline-wide, stakeholder-united redirection project. If it works, it will accomplish in one move what other disciplines are accomplishing, if at all, in halting steps. Finally, CERN is on track to accomplish this feat with fusion, not fission --or with cooperation and comity all around rather than antagonism and division. The payors (universities, labs, libraries, and funding agencies) may realize a net savings and the payees (publishers, journals) may realize a net gain in financial security.
Other disciplines don't have CERNs to coordinate analogous projects. In fact, no institution dominates any field the way CERN dominates particle physics. But every field has the same interest in removing access barriers and using subscription funds to a better purpose. To launch analogous projects, other fields don't need a CERN-like institution with great wealth or research dominance, only an institution with great convening power. There's good reason to believe that when the stakeholders convene, they will see the same win-win possibility in their fields that SCOAP3 members see in particle physics. Long live the peaceful revolution.

Ovaj "vremenski stroj" bi u trenutku pokretanja trebao prikazati točno što se događalo prije otprilike 14 milijardi godina. Protivnici ovog eksperimenta, među kojima su i sveučilišni profesori, podigli su tužbu kako bi se eksperiment zaustavio. Naime, oni su uvjereni kako bi taj stroj prilikom razbijanja čestica mogao stvoriti malene crne rupe, koje bi nezaustavljivo "gutale" svu materiju, uključujući i svjetlost koja ovom "svemirskom čudovištu" ne bi mogla umaknuti.
Igra Boga završila na sudu
U sudskoj se tužbi navodi kako se zadire u Božje i potpuno nepoznato područje čija moguća katastrofa ne bi utjecala samo na istraživački centar, već bi mogla prouzročiti nestanak planeta Zemlje i svakog života na njoj. Iako pokretači ovog eksperimenta iz Europskog centra za nuklearna istraživanja tvrde kako će malene crne rupe koje će nastati prilikom eksperimenta nestati, tužitelji upozoravaju kako to nije sto posto sigurno te da je opasnost prevelika.
