Will the LHC destroy the world?
http://www.youtube.com/watch?v=KETtEHX3pwo Sixty Symbols Published on May 9, 2012 CERN's Large Hadron Collider will NOT destroy our planet. But many of you asked about it - and the "scenarios" are a good excuse to discuss some cool physics. Dr Tony Padilla discusses a few doomsday theories from the very centre of the famed accelerator ring. Stand back and keep an eye out for black holes and strangelets!!! |

The Most Dangerous Stuff in the Universe -
Strange Stars Explained. http://www.youtube.com/watch?v=p_8yK2kmxoo Inside neutron stars we can find the weirdest and most dangerous substance in the universe: Strange matter. What is strange matter, how dangerous is it and what can it tell us about the origin of the universe? |

Could a Particle Accelerator Destroy Earth?
http://www.youtube.com/watch?v=P2GiHw9eagE Seeker Published on Dec 25, 2018 You may have heard theories that particle accelerators could destroy earth by creating strange matter, an accidental black hole, or by tearing the fabric of spacetime itself. But is there any real science behind these claims? |

Tiny black holes seem to be no problem as they have almost no mass so their gravity is too small to grow & they evaporate in less than a nanosecond however - strangelets are stable and seem dangerous. Watch the videos & see for yourself. They seem to be making strangelets at the LHC. |

See link: Link to How Stuff Works One fear is that the LHC could produce black holes. Black holes are regions in which matter collapses into a point of infinite density. CERN scientists admit that the LHC could produce black holes, but they also say those black holes would be on a subatomic scale and would collapse almost instantly. In contrast, the black holes astronomers study result from an entire star collapsing in on itself. There's a big difference between the mass of a star and that of a proton. Another concern is that the LHC will produce an exotic (and so far hypothetical) material called strangelets. One possible trait of strangelets is particularly worrisome. Cosmologists theorize that strangelets could possess a powerful gravitational field that might allow them to convert the entire planet into a lifeless hulk. Scientists at LHC dismiss this concern using multiple counterpoints. First, they point out that strangelets are hypothetical. No one has observed such material in the universe. Second, they say that the electromagnetic field around such material would repel normal matter rather than change it into something else. Third, they say that even if such matter exists, it would be highly unstable and would decay almost instantaneously. Fourth, the scientists say that high-energy cosmic rays should produce such material naturally. Since the Earth is still around, they theorize that strangelets are a non-issue. Another theoretical particle the LHC might generate is a magnetic monopole. Theorized by P.A.M. Dirac, a monopole is a particle that holds a single magnetic charge (north or south) instead of two. The concern Wagner and Sancho cited is that such particles could pull matter apart with their lopsided magnetic charges. CERN scientists disagree, saying that if monopoles exist, there's no reason to fear that such particles would cause such destruction. In fact, at least one team of researchers is actively looking for evidence of monopoles with the hopes that the LHC will produce some. Other concerns about the LHC include fears of radiation and the fact that it will produce the highest energy collisions of particles on Earth. CERN states that the LHC is extremely safe, with thick shielding that includes 100 meters (328 feet) of earth on top of it. In addition, personnel are not allowed underground during experiments. As for the concern about collisions, scientists point out that high-energy cosmic ray collisions happen all the time in nature. Rays collide with the sun, moon and other planets, all of which are still around with no sign of harm. With the LHC, those collisions will happen within a controlled environment. Otherwise, there's really no difference. Will the LHC succeed in furthering our knowledge about the universe? Will the data collected raise more questions than it answers? If past experiments are any indication, it's probably a safe bet to assume the answer to both of these questions is yes |

The only thing that will happen to the LHC is that it will soon collapse into a black hole of wasted Funds and never be seen again as they have to scrap it to sell to help repay the Debts that it accumulated for being the greatest Scientific waste of time and money. It's the Science version of Disneyland. Where Scientists can go and play 'Science' in a 'recreational' way bearing no importance at all - beyond other people having paid for it. ::)

Also, extra from:https://en.wikipedia.org/wiki/Strangelet
Need to wait to see the results of the investigation into neutron stars I guess. Dangers If the strange matter hypothesis is correct and a stable negatively-charged strangelet with a surface tension larger than the aforementioned critical value exists, then a larger strangelet would be more stable than a smaller one. One speculation that has resulted from the idea is that a strangelet coming into contact with a lump of ordinary matter could convert the ordinary matter to strange matter.[15][16] This "ice-nine"-like disaster scenario is as follows: one strangelet hits a nucleus, catalyzing its immediate conversion to strange matter. This liberates energy, producing a larger, more stable strangelet, which in turn hits another nucleus, catalyzing its conversion to strange matter. In the end, all the nuclei of all the atoms of Earth are converted, and Earth is reduced to a hot, large lump of strange matter. This is not a concern for strangelets in cosmic rays because they are produced far from Earth and have had time to decay to their ground state, which is predicted by most models to be positively charged, so they are electrostatically repelled by nuclei, and would rarely merge with them.[17][18] But high-energy collisions could produce negatively charged strangelet states which live long enough to interact with the nuclei of ordinary matter.[19] The danger of catalyzed conversion by strangelets produced in heavy-ion colliders has received some media attention,[20][21] and concerns of this type were raised[15][22] at the commencement of the RHIC experiment at Brookhaven, which could potentially have created strangelets. A detailed analysis[16] concluded that the RHIC collisions were comparable to ones which naturally occur as cosmic rays traverse the solar system, so we would already have seen such a disaster if it were possible. RHIC has been operating since 2000 without incident. Similar concerns have been raised about the operation of the LHC at CERN[23] but such fears are dismissed as far-fetched by scientists.[23][24][25] In the case of a neutron star, the conversion scenario seems much more plausible. A neutron star is in a sense a giant nucleus (20 km across), held together by gravity, but it is electrically neutral and so does not electrostatically repel strangelets. If a strangelet hit a neutron star, it could convert a small region of it, and that region would grow to consume the entire star, creating a quark star.[26] Debate about the strange matter hypothesis The strange matter hypothesis remains unproven. No direct search for strangelets in cosmic rays or particle accelerators has seen a strangelet (see references in earlier sections). If any of the objects such as neutron stars could be shown to have a surface made of strange matter, this would indicate that strange matter is stable at zero pressure, which would vindicate the strange matter hypothesis. However there is no strong evidence for strange matter surfaces on neutron stars (see below). Another argument against the hypothesis is that if it were true, all neutron stars should be made of strange matter, and otherwise none should be.[27] Even if there were only a few strange stars initially, violent events such as collisions would soon create many strangelets flying around the universe. Because a single strangelet will convert a neutron star to strange matter, by now all neutron stars would have been converted. This argument is still debated,[28][29][30][31] but if it is correct then showing that one neutron star has a conventional nuclear matter crust would disprove the strange matter hypothesis. Because of its importance for the strange matter hypothesis, there is an ongoing effort to determine whether the surfaces of neutron stars are made of strange matter or nuclear matter. The evidence currently favors nuclear matter. This comes from the phenomenology of X-ray bursts, which is well explained in terms of a nuclear matter crust,[32] and from measurement of seismic vibrations in magnetars.[33] |

Thanks Nova, that's interesting. I think that give such information that we should not build a larger particle accelerator. I hear that the Chinese want to build one 5 times larger than the LHC at CERN. https://www.popularmechanics.com/science/a25101820/china-lhc-particle-collider-cepc/ The Chinese institute announced plans to build its own particle accelerator over the next decade, and it’s designed to surpass the LHC in every way. According to the report authored by the institute, the upcoming collider will be over five times more powerful and over 20 miles in diameter.
