A pion decays into two photons with coupled (opposite) polarizations,
one of which passes into a black hole spinning clockwise
relative to an observer,and the other passes into a second black hole
also spinning clockwise relative to the same observer.After a long
period of time the photons emerge from the holes in the form of Hawking radiation which has coupled polarization to reflect the coupling of the original
photons that went into the holes.At a first glance,because of
CPT theorem this would suggest that black holes must always
spin in the same direction to preserve CPT symmetry.But isn't
it more likely that T symmetry can be broken and that the black holes
can spin in any direction? Then since T symmetry is broken what
is the CP violation that would go with it?
