| I'm bad at writing this kind of stuff.. Ask. =/ The world's largest and highest-energy particle accelerator, intended to collide opposing beams of protons or lead ions, each moving at approximately 99.999999% of the speed of light. The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics, including the existence of the hypothesised Higgs boson and of the large family of new particles predicted by supersymmetry. 27 kilometres (17 mi) in circumference, it lies underneath the Franco-Swiss border between the Jura Mountains and the Alps near Geneva, Switzerland. It is funded by and built in collaboration with over 10,000 scientists and engineers from over 100 countries as well as hundreds of universities and laboratories. On 10 September 2008, the proton beams were successfully circulated in the main ring of the LHC for the first time. On 19 September 2008, the operations were halted due to a serious fault when there was a helium leak rendering some magnets broken. The LHC will not be operational again until summer 2009. The LHC was officially inaugurated on 21 October 2008, in the presence of political leaders, science ministers from CERN's 20 Member States, CERN officials, and members of the worldwide scientific community. Purpose It is theorized that the collider will produce the elusive Higgs boson, the last unobserved particle among those predicted by the Standard Model. The verification of the existence of the Higgs boson would shed light on the mechanism of electroweak symmetry breaking, through which the particles of the Standard Model are thought to acquire their mass. In addition to the Higgs boson, new particles predicted by possible extensions of the Standard Model might be produced at the LHC. More generally, physicists hope that the LHC will enhance their ability to answer the following questions: -Is the Higgs mechanism for generating elementary particle masses in the Standard Model indeed realised in nature? If so, how many Higgs bosons are there, and what are their masses? -Are electromagnetism, the strong nuclear force and the weak nuclear force just different manifestations of a single unified force, as predicted by various Grand Unification Theories? -Why is gravity so many orders of magnitude weaker than the other three fundamental forces? See also Hierarchy problem. -Is Supersymmetry realised in nature, implying that the known Standard Model particles have supersymmetric partners? -Will the more precise measurements of the masses and decays of the quarks continue to be mutually consistent within the Standard Model? -Why are there apparent violations of the symmetry between matter and antimatter? See also CP-violation. -What is the nature of dark matter and dark energy? -Are there extra dimensions, as predicted by various models inspired by string theory, and can we detect them? Of the possible discoveries the LHC might make, only the discovery of the Higgs particle is relatively uncontroversial, but even this is not considered a certainty. Stephen Hawking said in a BBC interview that "I think it will be much more exciting if we don't find the Higgs. That will show something is wrong, and we need to think again. I have a bet of one hundred dollars that we won't find the Higgs." In the same interview Hawking mentions the possibility of finding superpartners and adds that "whatever the LHC finds, or fails to find, the results will tell us a lot about the structure of the universe." |
40 things God SHOULD have known: 1. The Universe began with light. (No Christians, God screwed up in verse 3 of Genesis because in verses 1 and 2 He already said He made the Earth and was hovering over "the waters" BEFORE there was light, and in verse 9 he said the world was first covered in sea, when it was too hot for puddle, and it wasn't until verse 16 that He made the stars, so just don't go there, ok?) 2. The light (energy) was too intense for anything else to exist. 3. Space expanded faster than light. Inflation, while still theoretical, is looking good). 4. Expansion reduced the energy density and allowed quarks to form. 5. All matter was formed from light/energy as per E=MC2. 6. Atomic nuclei remained "naked" for about 380,000 years after the B of the Bang due to the intensity of energetic photons (particles of light). After this point electrons were able to bond to atomic nuclei. 7. Accurate ratio of size between an atom and the Earth. 8. Vast (and I mean VAST!) clouds of the simplest atoms (mostly hydrogen) were able to gather under gravity. 9. At the core of such clouds, when massive enough, nuclear fusion began and emitted light. 10. Hydrogen atoms fuse to form helium releasing "unneeded" energy (light/heat) in the process. 11. Accurate numbers of stars per galaxy. 12. Accurate description of the shape of most galaxies (i.e., "discs"). 13. Each galaxy separated. 14. Each galaxy moving apart from all others at speed. 15. Accurate description of the numbers of galaxies in the visible Universe (though the actual number in existence will be far, far greater (but God/Allah didn't even mention ONE!). 16. Description of red dwarfs. 17. Description of blue giants. 18. The link between a star's mass, its light output and its life-expectancy (the rate at which it "burns" nuclear fuel). 19. The sequence of elemental "burning", from hydrogen (element 1) up to element 26 (with 26 protons), iron. Ordinary nuclear fusion cannot proceed any further as iron is too stable. 20. A star dies when it has fused all its silicon into iron. The end comes quickly, in tenths of a second, as the star, with no energy to "hold it up," collapses on its core. This is a supernova. 21. The collapse of the star briefly provides the energy to fuse heavy atoms, like iron, at the core into the less stable remainder of the table of chemical elements, up to element 92 (uranium) and beyond (the highly unstable plutonium for instance, at atomic number 94). 22. Chemical elements heavier than Hydrogen are produced in stars then spread out into the cosmos via supernovae. 23. The shockwaves from these events trigger the births of stars in "nearby", previously stable clouds of hydrogen gas, beginning the cycle again. 24. Second generation stars coalesced from the ashes of earlier stars and the first rocky planets formed out of the heavy elements produced by the first generation stars. 25. The "geography" of the solar system: The rocky, metallic planets of Mercury, Venus, Earth and Mars are to be found closer to the sun while the gas and ice giants of Jupiter, Saturn, Uranus and Neptune are to be found further out. 26. The relationship between orbital speed and distance from the star. 27. Earth was formed 9 billion years after the Beginning. 28. Due to the relatively low temperatures on Earth when compared to the stars, elements can form chemical bonds and grow in complexity. 29. Asteroid bombardment of the early Earth ("mountains from the sky"). 30. Chemical reactions proceed for approximately half a billion years before biogenesis occurs. 31. Chemical reactions caused by electromagnetism ("the law of the magnet and the lodestone"). 32. Absorption of early (poisonous) atmosphere by early organisms to produce a breathable atmosphere. 33. The sky of the Earth tuned blue only after life had begun, 500 million years after the planet's formation. 34. Asteroid bombardment largely over by this time. 35. Mankind in existence 4,000,000,000 later. 36. The study of the "solid and the light", the interaction of light and matter, of forces and matter, leads to physics. 37. Prediction of the coming of telescopes, from lenses made from sand. 38. Prediction of astronomical objects unknown at the time of the Bible or the Quran. 39. Prediction of black holes and their ability to "withhold" light. 40. The world is a sphere (the Qur'an DID contain this information, but then, contrary to what many believe, it was common knowledge at the time due to Eratosthenes discovering it almost 1,000 years BEFORE the Qur'an was written). Oh, and Allah said iron fell to Earth? Well, seeing as meteorites were well known LONG before then, and one sits at the heart of Mecca (the "Hadschar al Aswad"), and seeing as how Allah did not mention that the other 90+ elements also "fell from the skies", forgive me if I don't convert just yet. |
And for me I try to inspire people to think more than what they see..
