bumab Posted March 17, 2005 Report Share Posted March 17, 2005 http://news.bbc.co.uk/1/hi/sci/tech/4357613.stm Pretty cool! What are some of the difficulties of creating larger black holes, and if we could, would we be able to harness the energy potential? Or would we destroy the earth first... ;) Link to comment Share on other sites More sharing options...
Queso Posted March 17, 2005 Report Share Posted March 17, 2005 yeah that is pretty cool.i can just see somebody messing up and creating a stable one that last, and grows, and eats up our entire solar system. what a way to go, eh? Link to comment Share on other sites More sharing options...
maddog Posted March 18, 2005 Report Share Posted March 18, 2005 They didn't say the radius of the black hole. Being able to "swallow the earth" would be dependent uponthe surface area of the event horizon. A quantum sized black hole would likely be two small. I curious ifany of the telltale Hawking radiation was discovered. The article only implied. David Brin wrote a SFnovel about such a topic, called "Earth". Gregory Benford wrote another one about this experiment(smashing Au nuclei), called "Cosm". In this story was created a new universe. Interesting. ;) Maddog Link to comment Share on other sites More sharing options...
Qfwfq Posted March 18, 2005 Report Share Posted March 18, 2005 They didn't say the radius of the black hole. Being able to "swallow the earth" would be dependent upon the surface area of the event horizon.As things fall into it, increasing its mass, the Schwarzschild radius increases accordingly.

paultrr Posted March 18, 2005 Report Share Posted March 18, 2005 Also, with the type of quantum blackholes sometimes mentioned as being possible to create in a lab Hawking Radiation and their decay without infalling matter should apply. For larger Blackhole's where and how would one suggest we get the materials. There isn't at present enough material in our solar system to achieve such unless someone knows a way to compress matter down beyond a certain size. If you do let me know how.

Jay-qu Posted March 18, 2005 Report Share Posted March 18, 2005 I dont think a 'real' black hole could actually disappear as Qfwfg said mass falls in and it gets bigger... also if you wanted to turn the earth into a black hole you would have to condense all the mass into a ball with a radius of less than 9mm! so imagine turning sub-atomic particals into black holes...very small stuph...

Qfwfq Posted March 18, 2005 Report Share Posted March 18, 2005 If you do let me know how.I'll give it a thought, if I find the time! ;) Link to comment Share on other sites More sharing options...
