petrushka.googol Posted January 24, 2014 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.
Strange Posted January 24, 2014 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

Strange Posted January 26, 2014 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].
