a ver…la verdad que no creo que los del CERN sean tontos(que por ejemplo internet lo inventaron ellos, y simple lo qe se dice simple no es…), y no creo que tampoco ellos quieran morir en un puto agujero negro… y tener en cuenta que hay miles de cientificos en el proyecto… y además no van a emplear toda la energia de golpe, van a empezar con 0,45TeV, que no es muchisimo más que la energia que usan los aceleradores de hoy en dia, y se usan sin miedo. Y luego irán aumentando la energia poco a poco, pero sabiendo lo que pasa…hasta 7TeV que es el máximo de ese cacharrito(casi nah).
Y de todas formas no me acuerdo donde pero vi por ahí que en caso de crearse un agujero negro las distancias serían tan grandes que no podría absorber nada, y luego se dispersaria por la radiacción de hawkings o algo asi.Haber trinkete, yo dije, los cientificos estos, los de el proyecto este o esos k siempre estan con k vamos a morir todos y los de la nasa y toda esa gente del big ban y su culo pelao, no los k estan buscando la cura contra el cancer o similares, no generalizo. 😛
Los únicos que dicen que vamos a morir son 2 pringaos que no tienen ni puta idea, el Wagner es abogado y al Sancho se le va la olla de más. La comunidad científica (al menos los del campo de la física) sabe que no hay problema con el LHC
El domingo, en Discovery Channel echaron un reportaje sobre el LHC en la sección de “Cosas realmente grandes”
La verdad es que los números impresionaban: la circunferencia del acelerador principal tiene 30 kilómetros. Trabajan 7000 científicos, y estaba compuesto por fantastillones (*) de piezas fabricadas fuera.
(fantastillón = unidad seguida de una cantidad fantástica de ceros)
Uno de los científicos entrevistados dijo que en la colisión final, trataban de conseguir una materia de tamaño la cabeza de un alfiler pero masa equivalente a la de la Gran Pirámide de Keops. La temperatura también la dijeron pero era tal salvajada (¿300 millones de grados?) que se borró de mi mente casi al instante.
Vamos a mooriiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiirrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!!!!!!!!!!!!!!

The safety of the LHC
The Large Hadron Collider (LHC) can achieve an energy that no other particle accelerators have reached before, but Nature routinely produces higher energies in cosmic-ray collisions. Concerns about the safety of whatever may be created in such high-energy particle collisions have been addressed for many years. In the light of new experimental data and theoretical understanding, the LHC Safety Assessment Group (LSAG) has updated a review of the analysis made in 2003 by the LHC Safety Study Group, a group of independent scientists.
LSAG reaffirms and extends the conclusions of the 2003 report that LHC collisions present no danger and that there are no reasons for concern. Whatever the LHC will do, Nature has already done many times over during the lifetime of the Earth and other astronomical bodies. The LSAG report has been reviewed and endorsed by CERN’s Scientific Policy Committee, a group of external scientists that advises CERN’s governing body, its Council.
The following summarizes the main arguments given in the LSAG report. Anyone interested in more details is encouraged to consult it directly, and the technical scientific papers to which it refers.
Cosmic rays
The LHC, like other particle accelerators, recreates the natural phenomena of cosmic rays under controlled laboratory conditions, enabling them to be studied in more detail. Cosmic rays are particles produced in outer space, some of which are accelerated to energies far exceeding those of the LHC. The energy and the rate at which they reach the Earth’s atmosphere have been measured in experiments for some 70 years. Over the past billions of years, Nature has already generated on Earth as many collisions as about a million LHC experiments – and the planet still exists. Astronomers observe an enormous number of larger astronomical bodies throughout the Universe, all of which are also struck by cosmic rays. The Universe as a whole conducts more than 10 million million LHC-like experiments per second. The possibility of any dangerous consequences contradicts what astronomers see – stars and galaxies still exist.
Microscopic black holes
Nature forms black holes when certain stars, much larger than our Sun, collapse on themselves at the end of their lives. They concentrate a very large amount of matter in a very small space. Speculations about microscopic black holes at the LHC refer to particles produced in the collisions of pairs of protons, each of which has an energy comparable to that of a mosquito in flight. Astronomical black holes are much heavier than anything that could be produced at the LHC.
According to the well-established properties of gravity, described by Einstein’s relativity, it is impossible for microscopic black holes to be produced at the LHC. There are, however, some speculative theories that predict the production of such particles at the LHC. All these theories predict that these particles would disintegrate immediately. Black holes, therefore, would have no time to start accreting matter and to cause macroscopic effects.
Although stable microscopic black holes are not expected in theory, study of the consequences of their production by cosmic rays shows that they would be harmless. Collisions at the LHC differ from cosmic-ray collisions with astronomical bodies like the Earth in that new particles produced in LHC collisions tend to move more slowly than those produced by cosmic rays. Stable black holes could be either electrically charged or neutral. If they had electric charge, they would interact with ordinary matter and be stopped while traversing the Earth, whether produced by cosmic rays or the LHC. The fact that the Earth is still here rules out the possibility that cosmic rays or the LHC could produce dangerous charged microscopic black holes. If stable microscopic black holes had no electric charge, their interactions with the Earth would be very weak. Those produced by cosmic rays would pass harmlessly through the Earth into space, whereas those produced by the LHC could remain on Earth. However, there are much larger and denser astronomical bodies than the Earth in the Universe. Black holes produced in cosmic-ray collisions with bodies such as neutron stars and white dwarf stars would be brought to rest. The continued existence of such dense bodies, as well as the Earth, rules out the possibility of the LHC producing any dangerous black holes.
Strangelets
Strangelet is the term given to a hypothetical microscopic lump of ‘strange matter’ containing almost equal numbers of particles called up, down and strange quarks. According to most theoretical work, strangelets should change to ordinary matter within a thousand-millionth of a second. But could strangelets coalesce with ordinary matter and change it to strange matter? This question was first raised before the start up of the Relativistic Heavy Ion Collider, RHIC, in 2000 in the United States. A study at the time showed that there was no cause for concern, and RHIC has now run for eight years, searching for strangelets without detecting any. At times, the LHC will run with beams of heavy nuclei, just as RHIC does. The LHC’s beams will have more energy than RHIC, but this makes it even less likely that strangelets could form. It is difficult for strange matter to stick together in the high temperatures produced by such colliders, rather as ice does not form in hot water. In addition, quarks will be more dilute at the LHC than at RHIC, making it more difficult to assemble strange matter. Strangelet production at the LHC is therefore less likely than at RHIC, and experience there has already validated the arguments that strangelets cannot be produced.
Vacuum bubbles
There have been speculations that the Universe is not in its most stable configuration, and that perturbations caused by the LHC could tip it into a more stable state, called a vacuum bubble, in which we could not exist. If the LHC could do this, then so could cosmic-ray collisions. Since such vacuum bubbles have not been produced anywhere in the visible Universe, they will not be made by the LHC.Magnetic monopoles
Magnetic monopoles are hypothetical particles with a single magnetic charge, either a north pole or a south pole. Some speculative theories suggest that, if they do exist, magnetic monopoles could cause protons to decay. These theories also say that such monopoles would be too heavy to be produced at the LHC. Nevertheless, if the magnetic monopoles were light enough to appear at the LHC, cosmic rays striking the Earth’s atmosphere would already be making them, and the Earth would very effectively stop and trap them. The continued existence of the Earth and other astronomical bodies therefore rules out dangerous proton-eating magnetic monopoles light enough to be produced at the LHC.
Reports and reviews
Studies into the safety of high-energy collisions inside particle accelerators have been conducted in both Europe and the United States by physicists who are not themselves involved in experiments at the LHC. Their analyses have been reviewed by the expert scientific community, which agrees with their conclusion that particle collisions in accelerators are safe. CERN has mandated a group of particle physicists, also not involved in the LHC experiments, to monitor the latest speculations about LHC collisions.Que tengan ustedes salud hasta el día del experimento XD

si, pero resulta que para crear un agujero negro tendrias que meter tooooda la tierra en una cabeza de un alfiler, no una “mierda” de piramide. en cuanto a los grados…pues no es lo mismo que una estrella se ponga a esa temperatura, a que se libere durante una pequeñisima fracción de segundo y se deje de liberar, y a distancias tan grandes, que no digo que vaya a hacer frio por ahi pero…
Weno, el problema radica en la posibilidad de reacción en cadena. Los del LHA parten de la base de que su esperimento es análogo al impacto de un rayo cósmico sobre algo, pero a pequeña escala, y que los impactos de estos rayos, hasta ahora no han creado reacciones en cadena.
Yo por si acaso, la noche anterior al experimento, echaría una buena sesion de sexo si se tercia. Creo que el fin del mundo es la mejor excusa:
-Enga palomita, que mañana es el fin del mundo…
-¡Que pesao eres, cielo! además esta noche has cenado demasiado ajo.
-¡¡¡Pero que se termina el mundoooo!!! Hay que aprovecharlo porque… porque… ¿Qué haces con el móvil?
-Llamar al Teletienda. Voy a comprarlo TODO, jaja.
-¿Y cómo piensas pagarlo?
-¿No dices que mañana es el fin del mundo?Salud!!
Bueno señores, a sido un placer discutir con tod@s.
A follar a follar, k el mundo se vá a acabar y yo me voy por la pata abajo! 😀
Mañana encienden el cacharro! 😯Haciendo caso de una noticia comentada en un foro de musicos colgados y en previsión del apocalipsis, saqué ayer todo mi dinero del banco.
Me pegué una cena de cojones, me fui de putas y me puse borracho como una cuba.
Al llegar a casa, de madrugada, quemé todo el dinero que me sobró, llamé a mi casero para recordarle lo miserable y rata que es, y también para comentarle que estaba haciendo una hoguera, en la cocina, con las maderas del parqué.
Al tumbarme en la cama, me acordé de mi jefa (no me pregunteis por qué) y también la llamé para decirle que ya me había cansado de aguantar esa puta mierda de trabajo y que esperaba no volver a ver su puta cara de fulana jamás.
Hecho esto, lancé el teléfono móvil por la ventana (sin abrirla previamente).
Sale el sol, ya es miércoles 10.
A estas horas escribo desde mi ordenador portatil, sentado en un cojín, en un piso destrozado y con olor a quemado.
Suena una sirena de policía en la calle y oigo a los bomberos vocear por la escalera.
Rezo por que los cabrones del CERN pongan a gratinar los iones con los neutrones y que se les queme el guiso.vaya…. todavia no se ha acabado el mundo o estamos en un bucle espacio-tiempo en el que siempre es miercoles???
PD. para los agoreros… aun faltan unos dias para que empiezen a colisionar particulas asi que podeis seguir el discurso apocaliptico un pco mas ](*,)
No sé si tienen k colisionar las particulas, montarse unas encima de otras o qué, lo que sé es que el cacharro ya stá en marcha dsd sta mñn y pasando haces de luz por su interior.
Agorero? no creo, a mi todo eso k dijeron me la sopla bastante y hasta cierto punto me dá risa; lo que realmente me acojona es lo que NO te cuentan!Weno.. el propio Hawking ha apostado a que no encontrarán el bosón de Giggs. Él también sabe que VAMOS A MORIIIIIIIIIIIIIIIIIIIIIIIIRRRRRRRRRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!!
Se confirma …el mundo se va a la mierda……o no?….jijijijijiji a mi me vale se ponga como se ponga 😀
