Making Black Holes
An experiment at the Relativistic Heavy Ion Collider (RHIC) may have created a black hole, or its analog.
"A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said.
It was generated at the Relativistic Heavy Ion Collider (RHIC) in New York, US, which smashes beams of gold nuclei together at near light speeds.
Horatiu Nastase says his calculations show that the core of the fireball has a striking similarity to a black hole."
Nastase's paper which
"argue[s] that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large behaviour of the total QCD cross section is due to production of dual black holes, and that in the QCD effective field theory it corresponds to a nonlinear soliton of the pion field. Now we argue that the RHIC fireball is this soliton. . . . RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior."
