Abstract It is well known that a hypothetical particle which moves faster than the light, a tachyon, is unstable in the Minkowski space–time. Here we shall show that, contrary to the Minkowski case, the tachyon is stable in the rotating Universe described by a family of the Godel-like solutions, unless the absolute value of its mass is larger than some small constant which is related to the Universeʼs rotation scale and is many orders less than the electronʼs mass. The smallness of this upper… Expand
Supersonic Velocities in Noncommutative Acoustic Black Holes
In this paper we derive Schwarzschild and Kerr - like noncommutative acoustic black hole metrics in the (3+1)-dimensional noncommutative Abelian Higgs model. We have found that the changing in theExpand
