Title: 
Quantum mechanics without time, and the measurement problem

Abstract:
There should exist an equivalent reformulation of quantum theory, which does not refer to classical time. A consequence of this requirement is that quantum mechanics is a limiting case of a nonlinear theory, with the nonlinearity becoming more and more significant as the Planck mass/energy scale is approached.  This nonlinearity can help explain how, during a quantum measurement, the wave-function collapses to one of the outcomes in accordance with the Born probability rule. This proposal is in principle experimentally falsifiable through laboratory experiments on mesoscopic systems, since it predicts that linear superposition is an approximate principle of nature.
