What are the philosophical implications of the black hole information paradox? Would the creation of a small super dense residue of the black hole evaporation give rise to a philosophical issue anyway?

    Tim Maudlin has a very polemical essay on the topic where he argues that the entire idea of the information paradox, along with all of the resolutions that have been proposed by people like Susskind, are horribly misguided here. Here is a response by Manchak and Weatherall where they argue for the opposite and discuss the philosophical implications of the paradox. Susskind's ER=EPR and recent claims that GR=QM, taken in a literal way, have giant metaphysical implications. – Not_Here Jan 28 '18 at 19:13

    @Not_Here This looks almost like an answer. You could just add brief summaries of Maudlin's, Manchak-Weatherall's and Susskinds's speculations. – Conifold Jan 29 '18 at 0:32

There are no real direct consequences, in the sense that the information paradox is more a tension between the current understanding of gravity and quantum physics, that is General Relativity and Quantum Field Theory. It's widely believed that we will need a full theory of quantum gravity to understand the evaporation process of a black hole. This theory will of course have deep philosophical implications, but it's not possible to speculate further without any particular insight.

Regarding a possible black hole's residue, called black hole remnant in the literature, it's pretty much ruled out. Since the initial black hole can have arbitrary high mass and the entropy is proportional to the mass of the black hole, the remnant must be able to carry an arbitrary amount of information. Therefore there must be an huge number of stable remnant with mass comparable to the Planck scale and indistinguishable from an effective field theory viewpoint, so these remnant should appear inside quantum loops and evaporation process of other black holes. Even though the production of a single remnant will be highly suppressed, the huge phase space implies that the probability of generating a remnant is not negligible in a conventional process. But we know that quantum field theory works well, therefore we do not expect remnant to be present in our universe.
