* Information loss paradox:
There is an apparent paradox in the fact that, after a black hole has formed,
evaporated (with
creation
of a mixed state), and disappeared, most
the information about what went in it has disappeared with it, since the thermal
radiation is in a mixed state and can't carry the information; Various authors,
including Hawking
in 2004 with a well-publicized announcement, have suggested
that the resolution lies in quantum correlations.
* And observation: If
one takes into account what is actually seen in the processes of black hole
formation and objects falling into already formed black holes, one reaches
the conclusion
that (i) Unless there were black holes from the beginning, no fully formed
ones
can be seen, and (ii) No matter can be "lost" beyond the horizon.
* And CPT: The evaporation
process indicates that there is a preferred arrow of time, along which there
is a loss of information in the total process of
black hole formation and evaporation.
