• Title: A Modest View of the Black Hole Information Paradox
• Authors: Stephen Boughn
• Abstract summary: It seems to me the "paradox" has little to do with the physical world. For me, the concept of a quantum state is far more restrictive than required. Hawking's calculation of black hole evaporation is surely of limited applicability.

• Abstract: Thirty years ago, John Preskill concluded "that the information loss paradox may well presage a revolution in fundamental physics" and mused that "Conceivably, the puzzle of black hole evaporation portends a scientific revolution as sweeping as that that led to the formulation of quantum theory in the early 20th century." Many still agree with this assessment. On the other hand, it seems to me the "paradox" has little to do with the physical world but rather, at best, simply points out the possible inconsistency of two, already disparate, theories (mathematical models) of nature, general relativity and quantum mechanics, with virtually no conceivable observational consequences. The information paradox hinges on the concepts of a pure quantum state, the unitarity of quantum mechanics, and Hawking's semi-classical calculation of black hole evaporation. I used the qualifier "at best" above because, for me, the concept of a quantum state is far more restrictive than required by the paradox while unitarity is not a property of nature but rather of a mathematical model and is already violated by the process of making a measurement. Furthermore, the semi-classical calculation of Hawking is surely of limited applicability.

• Against (unitary) interpretation (of quantum mechanics): removing the metaphysical load [0.0]
  We show that "unitary quantum mechanics", which according to its followers leads to some interesting paradoxes, is an interpretation of quantum mechanics. The root of "unitary" vs. operational discrepancy is that the latter treats the measurement process as irreversible.

  We consider the Schr"odinger-Newton (SN) theory and the Correlated Worldline (CWL) theory, and show that they can be distinguished from conventional quantum mechanics. We find that discriminating between the theories will be very difficult until experimental control over low frequency quantum optomechanical systems is pushed further.

  The laws of quantum mechanics are couched in subtle mathematical language. Essential facts can be distilled into seven statements that are easy to remember and easily referred back. I take a few of the inadequacies of classical framework to illustrate that some of the complaints against Quantum Mechanics are patently misplaced.

• Unpacking Black Hole Complementarity [0.0]
  I explain how black hole complementarity provides a framework to articulate how quantum characterizations of black holes can remain consistent despite the information paradox. I point out that there are two ways to cash out the notion of consistency in play here: an operational notion and a descriptive notion.

  We show that the Page curve can still be realized even if information is lost and the information paradox can be attributed to the measurement problem. Though speculative, the similarities between the black hole information problem and the measurement problem may suggest some link in the origins of the two fundamental issues of distant fields.

• Demystifying Quantum Mechanics [0.0]
  We discuss the concepts of physical reality imposed by quantum mechanics, the role of the observer, prediction limits, a definition of collapse, and how to deal with correlated states. The discussion is carried out within the framework of accepting that there is in fact nothing important missing, rather we are just restricted by the limitations imposed by quantum mechanics.

  It is argued that the Schr"odinger equation does not yield a correct description of the quantum-mechanical time evolution of states of isolated (open) systems featuring events. A precise general law for the time evolution of states replacing the Schr"odinger equation is formulated within the so-called ETH-Approach to Quantum Mechanics.

• The Concept 'Indistinguishable' [0.0]
  All ordinary matter is made of electrons, protons, neutrons, and photons and they are all indistinguishable particles. The concept of indistinguishable particles has proved elusive, in part because of the interpretational difficulties that afflict quantum theory. I offer a deflationary reading of the concept "indistinguishable" that is identical to the Gibbs concept of "generic phase"
