As first emphasized by Wheeler, when matter disappears into a black hole, its
entropy is gone for good, and the second law seems to be transcended, made
irrelevant. A clue to resolving this puzzle came in 1970, when Demetrious
Christodoulou, then a graduate student of Wheeler's at Princeton, and Stephen W
. Hawking of the University of Cambridge independently proved that in various
processes, such as black hole mergers, the total area black hole has entropy
proportional to the ...

Superheated plasma jets hundreds of thousands of light years long were thrown
into space along the north and south poles of the spinning black holes. It was
possible to construct an artificial singularity using a small machine that generated
gravity inside it. When spacetime was warped sufficiently, an artificial singularity
the size of a molecule is formed. In the process, the micro black hole begins to
devour the machine which created it. As the machine collapses into the tiny black
hole, ...

6.1 Introduction In the preceding chapters we have explored the properties of two
highly symmetric vacuum solutions of the field equations of Einstein's general
theory of relativity, the Schwarzschild and Kerr black holes. For many years it was
expected that these black holes would turn out to be artifacts of high symmetry
and that real stars, being neither exactly spherically nor axially symmetric, would
not collapse to black holes. In that case black holes would be artificial
mathematical ...

Nature may even provide her own mirror, the radiation being reflected off a
plasma of interstellar particles trapped around the black hole but prevented from
falling into it by the radiation pressure. What vast explosions are occurring
through the cosmos when such powers are unleashed? Because of the difficulty
in making them, artificially produced black holes would not appear to be of value
even to the most advanced civilization and certainly not to ourselves. The most
important type ...

In fact, the majority of astrophysicists came to be of the opinion that this path of
evolution would be extremely artificial and rather unlikely. We thus conclude that
black holes are inevitably created at the late stages of evolution of massive stars.
Can black holes of nonstellar origin exist in the Universe? The answer is most
probably in the affirmative. Later in the book these very interesting and unusual
possibilities will be described. Actually, the conclusions on the existence of
nonstellar ...

Black holes. Their existence had been feared for decades, inspiring man with
awe throughout the twentieth century. There was a time we feared their presence
many light years away; there would be a time we would not fear their presence
meters away. The question isn't whether or not it is possible, but whether or not
we'll still have any use of them when we can create them. It's certainly possible
that they could be used on astronomical schale: ironically, black holes could
potentially ...

Roughly speaking, if the Planckian degrees of freedom generate interactions with
respect to the global rest frame of the black hole instead of the (local) freely
falling frame, one may well obtain instabilities which generate deviations from
Hawkings result, for example. In summary, one reproduces the Hawking effect for
a rather large class of scenarios, but there are also counter-examples, which do
not appear to be unphysical or artificial, displaying strong deviations from
Hawkings ...
