“The idea that [the alternate measurement outcomes] be not alternatives but all really happening simultaneously seems lunatic to [the quantum theorist], just impossible. He thinks that if the laws of nature took this form for, let me say, a quarter of an hour, we should find our surroundings rapidly turning into a quagmire, a sort of a featureless jelly or plasma, all contours becoming blurred, we ourselves probably becoming jelly fish. It is strange that he should believe this. For I understand he grants that unobserved nature does behave this way – namely according to the wave equation. . . . according to the quantum theorist, nature is prevented from rapid jellification only by our perceiving or observing it.” --Erwin Schroedinger, The Interpretation of Quantum Mechanics. Dublin Seminars (1949-1955) and Other Unpublished Essays s. ------------------------ The actual quote was a bit different and IMO much more interesting. Here the correct quotation. “The idea that they [measurement outcomes] be not alternatives but *all* really happen simultaneously seems lunatic to him [to the quantum theorist], just *impossible*. He thinks that if the laws of nature took *this* form for, let me say, a quarter of an hour, we should find our surroundings rapidly turning into a quagmire, or sort of a featureless jelly or plasma, all contours becoming blurred, we ourselves probably becoming jelly fish. It is strange that he should believe this. For I understand he grants that unobserved nature does behave this way – namely according to the wave equation. The aforesaid *alternatives* come into play only when we make an observation - which need, of course, not be a scientific observation. Still it would seem that, according to the quantum theorist, nature is prevented from rapid jellification only by our perceiving or observing it. [........] The compulsion to replace the "simultaneous* happenings, as indicated directly by the theory, by *alternatives*, of which the theory is supposed to indicate the respective *probabilities*, arises from the conviction that what we really observe are particles - that actual events always concern particles, not waves." -Erwin Schroedinger, The Interpretation of Quantum Mechanics.
