Black Holes, Information Loss and the Measurement Problem

TL;DR

This paper critically examines the black hole information loss paradox, emphasizing the speculative assumptions involved and exploring various potential resolutions, while highlighting the connection to the quantum measurement problem.

Contribution

It clarifies the assumptions behind the paradox and maps out the different approaches to resolving it, emphasizing the link to the measurement problem.

Findings

The paradox relies on speculative assumptions about quantum effects on spacetime.

Different resolutions demand specific, often overlooked, commitments.

The black hole information loss issue is closely connected to the quantum measurement problem.

Abstract

The information loss paradox is often presented as an unavoidable consequence of well-established physics. However, in order for a genuine paradox to ensue, not-trivial assumptions about, e.g., quantum effects on spacetime, are necessary. In this work we will be explicit about these additional, speculative assumptions required. We will also sketch a map of the available routes to tackle the issue, highlighting the, often overlooked, commitments demanded of each alternative. In particular, we will display the strong link between black holes, the issue of information loss and the measurement problem.
