- barrkel 17y agoVery good.
- Tuna-Fish 17y agoMy first thought was: "That's not what it would look like." I'm too much of a geek.
- JshWright 17y agoOr not enough of one...
- Tuna-Fish 17y agoPlease elaborate. What I meant was that if they did make a black hole, and it for some reason would stay on earth (instead of being flung out of the solar system at an appreciable fraction of the speed of light), all the matter on earth would form a black hole with a Schwarzschild radius of less than 1 cm. Thus, a black hole created at rest at CERN devouring the earth would never be seen -- it would just fall down and let the pressure of earth push matter into it. Done properly, the webcam feed should show a pretty major earthquake that just keeps getting worse.

- russell 17y agoWrong. Any black hole produced at CERN Would evaporate instantly. http://en.wikipedia.org/wiki/Micro_black_hole http://en.wikipedia.org/wiki/Micro_black_hole If it were possible to create an earth eating black hole, cosmic rays would have done the job long ago. They are way more powerful than the LHC.
- Tuna-Fish 17y agoI am aware of Hawking radiation, but it does not properly explain how a black hole would evaporate after reaching Planck mass, only that it would reduce in mass until it was unable to attract anything. (There is a very reasonable proposal that black holes thus reduced would actually be stable weakly interacting massive particles, and would form much, if not all, of dark matter.) Also, if a black hole would be created at CERN, it would be fed by a very energetic proton beam, potentially much faster than it could possibly evaporate by hawking radiation. That cosmic rays also potentially produce black holes is also not a good argument against their production, but only against the danger they pose. A black hole with the mass of a few grams has a very tiny cross-section, and since momentum is conserved, would probably be moving very close to the speed of light. Should a cosmic ray hit earth and produce one, it would likely pass right trough earth without hitting any significant amount of matter or slowing down. This is of course also true for any black hole created at CERN -- The protons traversing the rings are doing so at roughly 0.99999999c. Should a black hole be created, it would leave the solar system in a rather short time, at least from it's perspective.
- JshWright 17y agoSorry, I didn't actually click the link to the joke webcast, I assumed it was just a normal webcast, and that you expected more blinken' lights or something. Your comment makes much more sense when I bother to find out the full context.
- barrkel 17y agoFWIW, the reason I replied was to attract attention to the joke, rather than praise, per se. But I also didn't want to give the joke away.
- rick_2047 17y agoI don't understand the video, its like the LHC got eaten by a worm hole or black hole or some kind of other hole. Can anyone please tell me what exactly this means?
- tlrobinson 17y agoTis a joke. Some people speculated that there's a chance the LHC could cause a black hole. See also: http://hasthelargehadroncolliderdestroyedtheworldyet.com/ http://hasthelargehadroncolliderdestroyedtheworldyet.com/
- russss 17y agoAll incredibly old jokes aside, you can see the actual live webcams from the CMS experiment here: http://cms.web.cern.ch/cms/Media/CMSeye/index.html http://cms.web.cern.ch/cms/Media/CMSeye/index.html
