• Title: On playing gods: The fallacy of the many-worlds interpretation
• Authors: Luis C. Barbado and Flavio Del Santo
• Abstract summary: We present a methodological argument to refute the so-called many-worlds interpretation (MWI) of quantum theory. We show, in fact, that a whole class of theories--of which MWI is a prime example--fails to satisfy some basic tenets of science which we call facts about natural science.

• Abstract: We present a methodological argument to refute the so-called many-worlds interpretation (MWI) of quantum theory. Several known criticisms in the literature have already pointed out problematic aspects of this interpretation, such as the lack of a satisfactory account of probabilities, or the huge ontological cost of MWI. Our criticism, however, does not go into the technical details of any version of MWI, but is at the same time more general and more radical. We show, in fact, that a whole class of theories--of which MWI is a prime example--fails to satisfy some basic tenets of science which we call facts about natural science. The problem of approaches the likes of MWI is that, in order to reproduce the observed empirical evidence about any concrete quantum measurement outcome, they require as a tacit assumption that the theory does in fact apply to an arbitrarily large range of phenomena, and ultimately to all phenomena. We call this fallacy the holistic inference loop, and we show that this is incompatible with the facts about natural science, rendering MWI untenable and dooming it to be refuted.

  We characterize the full range of quantum feedback control and erasure protocols that are consistent with the second law of thermodynamics. This leads us to conclude that the second law of information thermodynamics is indeed universal.

  It is argued that the MWI is the only interpretation which removes action at a distance and randomness from quantum theory. Some speculations about misconceptions, which apparently prevent the MWI to be in the consensus, are mentioned.

• Reply to "Comment on 'Why interference phenomena do not capture the essence of quantum theory' " [0.0]
  We argue that the phenomenology of interference that is traditionally regarded as problematic does not, in fact, capture the essence of quantum theory. It does so by demonstrating the existence of a physical theory, which we term the "toy field theory", that reproduces this phenomenology but which does not sacrifice the classical worldview.

  I propose a slight addition to standard textbook quantum mechanics, in the form of two rules, which avoids the paradox. The first specifies when a given quantum dynamics can be interpreted as a measurement. The second requires that a joint context be used to determine whether several different dynamical evolutions can all be interpreted as measurement.
