Hi all i just seen in our news channel about this Bag Band Machine i am surprise dome of channel told earth finish if project is unsucessful. Here is details about that The Large Hadron Collider (LHC) will smash two beams of particles head-on at super-fast speeds, recreating the conditions in the Universe moments after the Big Bang Scientists hope to see new particles in the debris of these collisions, revealing fundamental new insights into the nature of the cosmos. They will be looking for new physics beyond the Standard Model – the framework devised in the 1970s to explain how sub-atomic particles interact. The Standard Model comprises 16 particles – 12 matter particles and four force-carrier particles. The Standard Model has worked remarkably well so far. But it cannot explain the best known of the so-called four fundamental forces: gravity; and it describes only ordinary matter, which makes up but a small part of the total Universe. Also, one of the most important particles in the Standard Model – the Higgs boson – has yet to be found in an experiment. Today, the Standard Model is regarded as incomplete, a mere stepping stone to something else. So the LHC should help reinvigorate physics' biggest endeavour: a grand theory to explain all physical phenomena in Nature. However, some physicists point out that Nature has a habit of throwing curve balls. And some of the most exciting discoveries at the LHC could be those that no-one expects. THE HUNT FOR THE HIGGS There is an essential ingredient missing from the Standard Model. Without it, none of the 16 particles in the scheme would have any mass. An extra particle is required to provide all the others with mass – the Higgs boson. This idea was proposed in 1964 by physicists Peter Higgs, Francois Englert and Robert Brout. According to their theory, particles acquire mass through their interactions with an all-pervading field, called the Higgs field, which is carried by the Higgs boson. It is the only Standard Model particle that has yet to be observed experimentally. As such, the search for the Higgs has become something of a cause celebre in particle physics. Finding the Higgs is one of the main science objectives for the LHC. The Atlas and CMS experiments are both designed to see it, if it is there. This means that scientists working on these respective experiments will be competing to see it first, once the LHC begins its "science run" sometime in 2009. The US Tevatron particle accelerator, though less powerful than the LHC, is also engaged in the hunt for the Higgs. IN THE DARK All the matter that we can see in the Universe – planets, stars and galaxies – makes up a minuscule 4% of what is actually out there. The rest is dark energy (which accounts for 70% of the cosmos) and dark matter (26%). Dark energy cannot be observed directly, but it is responsible for speeding up the expansion of the Universe – a phenomenon that can be detected in astronomical observations. Astronomers have mapped dark matter's distribution, but have no idea what it is Like dark energy, dark matter can only be detected indirectly, as it does not emit or reflect enough light to be seen. But its presence can be inferred through its effects on galaxies and galaxy clusters. Physicists know virtually nothing about the nature of either dark energy or dark matter. But they can speculate. According to one idea, dark matter could be made up of "supersymmetric particles" - massive particles that are partners to those already known in the Standard Model. A leading dark matter candidate is the neutralino, the lightest of these "super-partners". And some theoretical physicists have proposed a link between the Higgs mechanism and dark energy. MIRROR, MIRROR Each basic particle of "ordinary" matter has its own anti-particle. Matter and antimatter have the same mass, but opposite electric charge. For example, a proton has an anti-particle called an anti-proton (a proton with a negative charge). An electron has an anti-particle called a positron (an electron with a positive charge). In the same way that an ordinary proton and electron can come together to form a hydrogen atom, an anti-proton and a positron can form an atom of anti-hydrogen. When a particle of ordinary matter meets its anti-particle, the two disappear in a flash, as their mass is transformed into energy. They are said to "annihilate" one another. But equal amounts of matter and anti-matter must have been produced in the Big Bang. So why did matter and anti-matter not completely annihilate each another after the birth of the Universe? Today, we live in a Universe almost entirely composed of ordinary matter. Scientists will use the LHC to investigate why this is, and what happened to all the anti-matter. DOUBLE TROUBLE Attempts to unify gravity with the other fundamental forces have come to a startling prediction: that every known particle has a massive "shadow" partner particle. All particles are classified as either fermions or bosons. A particle in one class has superpartner in the other class, "balancing the books" and doubling the number of particles in the Standard Model. For example, the superpartner of an electron (a fermion) is called a selectron (a boson). Evidence for supersymmetry would enable the "unification" of three fundamental forces - the strong, weak, and electromagnetic – helping to explain why particles have the masses they have. It would also give a boost to string theory – one stab at a grand "theory of everything". But string theory is not dependent on discovering evidence for supersymmetry. OTHER DIMENSIONS In addition to the four dimensions we already know about, string theory predicts the existence of six more. Some physicists even think the existence of these extra dimensions could explain why gravity is so much weaker than the other fundamental forces. Perhaps, they argue, we are not feeling its full effects. This might be explained if its force was being shared with other dimensions. If these extra dimensions do exist, the LHC could be the first accelerator to detect them experimentally. At high energies, physicists could see evidence of particles moving between our world and these unseen realms. For example, they could see particles suddenly disappear into one of these dimensions. Alternatively, particles originating from an extra dimension could suddenly appear in our world. THE HOLE TRUTH According to some physicists, the LHC can operate at high enough energies to generate mini-black holes. However, the vast majority of particle physicists say there is no need for alarm. If any should be created, they should evaporate quickly. A recent report dealing with the collider's safety acknowledged the possibility that the LHC could create these primordial black holes. The report says: "If microscopic black holes were to be singly produced by colliding the quarks and gluons inside protons, they would also be able to decay into the same types of particles that produced them.†The suggestion that black holes could be made in the LHC has stoked fears that one of these micro-black holes could swell in size, swallowing up the Earth. In March, plaintiffs requested an injunction in a US court stopping the LHC from switching on. However, physicists stress that any such phenomena would be short-lived and thus would pose no threat to our planet. Source : http://news.bbc.co.uk/2/hi/science/nature/7567926.stm
I find in to be a useful experiment in the development of physics. A field that seemed so old before Einstein and is now probably the most fascinating to follow and see how it develops.
Science would always go by experiments to gather and analyze data and find more useful and interesting things for the mankind... Nothing would have been achieved if human mind was not inquisitive or didn't have permission to experiment... I just hope that black hole theory is a hoax .. as propagated by some segments opposing these experiments
Well if it goes bad and sends us in a black hole I hope there time to put you head between your knees and kiss you a$$ goodbye.
It could create a black hole, it could also create a pink an purple checked tartan elephant. The truth is its never been done on this scale before so no-one really knows what will happen. Several theorists have said it could create a black holem, but bcause there is no way of figuring out what will hapen tehy are infact just making it up. Most physicists (Spelling?) have agreed that a black hole cannot be created due to lack of mass in the vacuum, anything that would be created would get ripped apart by the earths own gravitational forces. What is more concerning is the fact that they are nudging closer to how they think the big bang might have started, emaning that they could accidentally trigger another one, which really would cause problems on earth
Well the experiment will be start on 12th sep, but i think scientists will take all saftely measures before starting such a huge experiment.
but what if they create a door to another "dimension" where theres plenty of mass? just a wild uneducated guess of mine but i know as much as they do what will happen= no clue... am i the only one who is bothered by the name "Large Hadron Collider" that sounds exactly like something that could end the earth LOL...
I think we're totally safe tbh, but can see why people are getting worried. I blogged on this very subject: http://www.asap.co.uk/blog/will-the-lhc-mean-the-end.htm I like the other dimension idea - wasn't that like Half Life?
Few facts, The black hole theory came form conspiracy theorists not scientists, the scientists only said they couldnt say it wouldn't make a black hole that would destroy the Earth. Imagine it as a game of conkers, played at near lightspeed, but with conkers an atom big. All they are really looking for is teh component parts of the smallest possible particles.
The news which we are getting confirms one thing at least that this experiment will be carried out at any cost despite of the risk factors. There are chances that black holes will form but scientists are saying that there is nothing to worry about them as they will be very small in size. I am not able to understand that why they are not taking it seriously because the holes -can grow in size no matter how much controlled experiment it will be. God knows what will happen on 10th, opening day of experiment.
Its said Bermuda triangle is also a black hole but it doesnt seem to grow.. i dont think thats how it works
Thank goodness I am blissfully unaware that the Earth might be destroyed from this experiment.. until I read this thread that is
I'm sick of read this on the internet now, people having unreliable information and spreading it. This is whats going to happen; Particles are going to be fired round a 17mile (27km) tunnel through the border of France & Switzerland to discover science that has not yet been explained. This like; Particles (Atoms, Neutrons, Electrons, etc) - we will see if they exist. We will also discover the 5th, 6th, 7th, 8th, 9th, 10th & 11th dimensions, if they exist. Also, a 100th of a second after the big bang will be created. If this experiment succeeds, it will be a science breakthrough & the aspect of science will totally change. Although just like everything, something could go wrong. This experiment could not work at all or a black hole could be created. Theorys have been created by scientists that it may be small but others think if it goes wrong, the whole earth will be sucked in. No one really knows what is going to happen tomorrow. It will be monitored by around ~2000 scientists with special equipment. The tunnel is currently 100 or so metres under the ground. The chance of something happening? Nobody knows. But we should be pretty safe with all them scientists and equipment. Thats everything and it's correct information, How do I know all this? A friend of mine works as a secondary school physics teacher and visited CERN with information and a tour round the facility.
This is happening first time and scientist says its safe but realy they don't know what happen actually with big ben. What if something wrong with blackwholes ? Our news channels daily show the reports about this and many scientist excitied to see the result of this and many are unhappy with this. So what's going with this its on future !!! Happy Big Bang
Wow, what can i say, good excuse to stop working, go home and pig out on good junk food and watch junky movies!!! Thank you for this thread!!! Hmmm....dont really want to die though....damn....to enjoy myslef or not on such an occasion, that is the question....
