except 2nd author Military-Medical Academic Serbia, in "Single horizon
black hole 'Laser' and a solution of the information loss paradox," 15
pages, arXiv: 0807.1840 v1 [gr-qc] 11 Jul 2008, have obtain a single
horizon black hole behaving as a laser concetpually analogously in
many ways to Carley and Jacobson's work on a 2-horizon black hole
"laser".
Their solution to the "information loss paradox" involves a duality
between macroscopic and microscopic black hole scenarios in which the
former changes to the latter and prompts stimulated emission - so
information isn't lost due to emission of laser light. The duality is
analogous to string theory T-duality, here involving the horizon
radius R being inverse to the horizon radius of its dual R1 and vice
versa. There is a similar duality between minimal system mass m1 and
macroscopic black hole mass M. For a macroscopic black hole, M >> m1,
while for microscoic black hole m1 > = M_P > = M (M_P is Planck
mass). A Schwarzschild black hole has mass M and Schwarzschild radius
R = 2GM/c^2, G the gravitational constant.
In Probable Causation/Influence (PI), Causation is always emphasized,
and from a Causal viewpoint black holes and similar singularities play
a key role in generating mass, for example because of the association
of central galactic black holes with new stars. The laser scenario
makes the most sense from the viewpoint of PI as generating mass via a
black hole laser operating on the "structure" of spacetime itself.
This would probably occur before the alleged evaporation of black
holes to a relatively "weak level" from the viewponit of PI, but it is
encouraging to see it occurring at all even in well-motivated theory.
