Re: Creating "Sparks"

So if anything terrible would be created by high energy particles striking a dense target that they can not escape from neutron stars would only excist for a neglegible time. Yet we do see fast numbers of neutron stars. Check this out: Chandra observations of RX J1856.5-3754 (a neutron star) and th...

Re: Creating "Sparks"

The higest energies recorded in cosmic rays is about 3*10^20 eV, which is 8 orders of magnitude higher then the LHC energy and can not possibly be reached by a manmade machine. From all we know nature does not allow global doomsday scenarios, because if it would the universe would have ended long b...

He who gives up freedom for security, deserves neither ... Benjamin Franklin Well, if we start trowing quotes around, how about this one: "Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direc...

Re: Creating "Sparks"

Atmosphere didn't burn not because we were lucky but because there is no chance it can burn. And people involved in the program knew it because they were actually able to do all necessary calculations. Calculations aren't always right, therefor testing, check out this story of 'The Lucky Dragon": W...

Re: Creating "Sparks"

Interesting comments, but I cannot help to say: most of them are not exactly referring to the questions asked, but they sure contain backgroundknowledge which helps to make your own thoughts about the questions. The most important answer is the one about the conservation of energy, combined with th...

Re: Creating "Sparks"

Hello everybody :wave: I've been asking my question at Dr. David P. Stern autor of the website: Educational Web Sites on Astronomy, Physics, Spaceflight and the Earth's Magnetism ( http://www.phy6.org/ ), and he has given me a lot of answers, perhaps some of you might be interested. Here's a report ...

Re: SBU Professor, Puts “Doomsday” Scenarios in Perspective

There is a slight difference between the following two sentences: 1. I wonder whether LHC is going to create magnetic monopoples and whether they may be dangerous. 2. LHC will create a magnetic monopole and it will kill us all! That's my way of distinguishing curious people from panic spreaders. An...

Re: SBU Professor, Puts “Doomsday” Scenarios in Perspective

Too bad we know this won't stop MagneticTrap from trying to create panic. :think: I have little bit of trouble with people often accusing others of wanting to create "Panic". I find that to be a bit of an intimidation towards people who want to ask questions. And if you even say something could hap...

Re: Review of not considered risks (Energia Incognita)

Not to be paranoid or anything, but are you 100% sure an airplane will not crash into your house this or any following night? As opposed to wild theories about LHC, there is lots of evidence that airplanes can be very deadly and can crash into houses... Check this out, it's in dutch but I think it'...

Re: Creating "Sparks"

Hello, I've been discussing this "sparks" thing somewhere else after that "energy inconita" post and got an aswer to this old question of the difference between the LHC-beam an Cosmic ray particles: Maybe think of a hose nozzle - it can either be a tight beam (LHC), or a spray (Cosmic). This is the ...

Re: Review of not considered risks (Energia Incognita)

If you honestly believe that then you have my deepest sympathy. No need to sympathise with me, I believe that we humans are the smartest in the universe, and that things won't get this far, sooner or later wisdom will arise and we'll find a way to pass by the issues that we don't understand at this...

Well Stephen with that confession, I guess I will just have to label you a luddite then. haha, I never heard of that "term" I just checked the dictionary and as it turns out: Luddite: a member of any of the bands of English workers who destroyed machinery, esp. in cotton and woolen mills, that they...

Re: Review of not considered risks (Energia Incognita)

Not to be paranoid or anything, but can someone read and disprove these claims? Look this experiment is a race that we are going to win, ask any pilot mh I mean particle scientist if it's safe, and he or she will say a full 100% yes, no risk. If there is anything that might pop up it would be like ...

Review of not considered risks (Energia Incognita)

Hi,

I dunno if anyone is still interested in questioning risk ...

Anyway I thought that this article was interesting, the guy brings up some of the points that I also mentioned, and thought were sensible, check it out:

Re: Creating "Sparks"

An interesting update on Cosmic Rays: NASA's Fermi Closes on Source of Cosmic Rays Young supernova remnants seem to possess both stronger magnetic fields and the highest-energy cosmic rays. Stronger fields can keep the highest-energy particles in the remnant’s shock wave long enough to speed them to...
