petrushka.googol Posted January 24, 2014 Share Posted January 24, 2014 Is it possible to create super-density like a black hole or neutron star in a particle accelerator for even an iota of time like a femtosecond? And what are its long term implications? Please advise. Thanks in advance. Link to comment Share on other sites More sharing options...
Strange Posted January 24, 2014 Share Posted January 24, 2014 It is possible in principle. If a microscopic black hole was created, it would decay almost immediately. There is no evidence it has happened: http://arxiv.org/abs/1012.3375 Link to comment Share on other sites More sharing options...

Strange Posted January 26, 2014 Share Posted January 26, 2014 (edited) Identify the principle, please. Achieving sufficiently high energy and density, I suppose. A lot of analysis was done when the LHC was built (mainly in response to fear mongering, I think, rather than because it was thought a likely possibility). From the linked paper: One of the exciting predictions of theoretical models with extra spatial dimensions and low- scale quantum gravity is the possibility of copious production of microscopic black holes inparticle collisions at the CERN Large Hadron Collider (LHC) [1, 2].
