John von Neumann:

In a chapter of The Mathematical Foundations of Quantum Mechanics, von Neumann deeply analyzed the so-called measurement problem. He concluded that the entire physical universe could be made subject to the universal wave function. Since something "outside the calculation" was needed to collapse the wave function, von Neumann concluded that the collapse was caused by the consciousness of the experimenter (although this view was accepted by Eugene Wigner, the Von NeumannWigner interpretation never gained acceptance amongst the majority of physicists).

Please answer a question about this article. If the question is unanswerable, say "unanswerable". Were von Neumann's conclusions of collapse of entire universe cause accepted widely?
