damnit insomnia you got there first!
tomorrow, the thing wont even get up to energy levels exceeded by other accelerators, its a test run.
awesome thing when you read about it, its at ~ 271 deg c so the magnets are cold enough to become superconducting, this makes it the coldest ring in the universe, as long as an alien civilisation hasnt built one already, of course its also the most complete vaccuum ever, since the ring has to be empty of ANY particles. ____________________ killa wrote: Im an ass man myself |

Sorry luc
Also, to put some of your minds at ease (In case any of you think the Earth is going to be sucked into a black hole);
When a star begins to die, it expands and becomes.. well.. huge. Once it's run out of energy, the entire mass of the star is pulled into it's centre by the force of gravity. A small star, like our sun, will be condensed into a small (relatively), but incredibly dense celestial body known as a white dwarf.
If the star has enough mass, the sheer force of the implosion of the star creates something so dense in such a small area of space that it becomes what we call a black hole.
So, to summarise, simply put if we wanted to create a black hole capable of sustaining itself, we'd need to be messing with quantities of mass that exceed that of our sun.. Which clearly, we aren't ____________________ Yamaha YB100 | Yamaha TZR125 | Yamaha XJ600S | Suzuki GSF600

Indeed...
You'd need in excess of 9 times our sun's mass to do it... Only remember that from astronomy club, plus type1 and type 2 supernova... Type 1 I think forms new nebulae and type 2 tend to be more massive and collapse in on themselves...
I remember something about the Chandrasekhar limit but it escapes me...
This chat about it being the coldest ring and the most complete manmade vacuum makes it sound like a household appliance, it'll do the sitting room carpet as it chills your beer...
I wonder if it plays CD's??

Nope, but it could fire a CD around the ring at 266 million mph

going to sound terribly geeky here but I always thought it was density rather than mass.
In that objects become black holes once they are smaller than their schwartschild radius, therefore if you managed to compress the earth into a peanut it would become a blackhole according to Wiki (I did physics at college about this about 12 years ago now oh man i sound old), thus the mass is only important for 'naturally' occuring black holes as the gravity needed to compress it is provided by the mass. ____________________ Spain 2008France 2007Big one 2009 We all die.

Really haven't got time to read all that, but afterwards it can be used in the JET project, which with enough development could realistically solve all our energy problems.
So Hetz the thing you said about why aren't they finding new options, they are, eventually
I would like to add I don't think that this is why they funded the LHC, but it is useful. ____________________ Don't practice it until you get it right, practice it until you don't get it wrong.
