alternative to the
Copenhagen interpretation, both seeking to understand the deepest meaning of quantum mechanics. The need for an interpretation is because the extremely-well-verified equations of quantum mechanics leaves unaddressed various issue concerning the nature of reality, the ultimate accuracy of measurement, hidden variables, and the idea of multiple universes. The issues revolve around the nature of the collapse of the quantum wave function as made by a measurement, with the famous example being understanding of Schroedinger's Cat. The Montevideo interpretation adds gravity into the picture, where there must be fundamental limits on the accuracy of any clock, and this introduces a decoherence into all systems, which acts as a measurement. "This interpretation explains the emergence of the classical world via decoherence through the interaction with the environment plus loss of coherence of the quantum theory when studied with real clocks and measuring rods... The combined effect of both losses of coherence implies that all information about quantum coherence in the system plus apparatus plus environment becomes inaccessible. After a while, there is no experimental arrangement that is able to decide if the evolution of the state of the complete quantum system was unitary or suffered a collapse. Whenever such situation of undecidability is reached, the interpretation assumes that an event (measurement) takes place." The physics of the Montevideo interpretation is all classical quantum mechanics and General Relativity, but the philosophical implications are deep.

Pullin is also known for a series of papers on the theory and numerical simulation of colliding black holes. Pullin's early work on the subject (including his second most cited paper, from 1994) involves the "close approximation" in which a pair of nearby black holes is treated mathematically as a

Pullin, along with R. Gambini, has proposed a new interpretation of quantum mechanics, called the `Montevideo interpretation'. This name was chosen for its similarity with the more orthodox `Copenhagen interpretation' and a reference to the city of origin. The
Montevideo interpretation is an
