    I Would this experiment disprove that consciousness causes collapse?

    No. From the answers, I gather the convincement that what happens in the apparatus only depends on how the apparatus has been prepared and what is running in. It is not influenced by human knowledge. And this is pretty fine because it confirms a realism principle about Nature. Knowledge is...

    I Wheeler's delayed choice doesn't change the past

    "Obviously, deductions or interpretations would be more mingled with the theory on the bench than it occurred [in] the past." I missed [in] before "the past". But I see it is not enough to make sense of this thought of mine. I'll try to express it better. First, usual theories address what is...

    I Wheeler's delayed choice doesn't change the past

    I like your wise reply and opinion about Copenhagen break up between micro/macro realities. That means that either the theory is incomplete or classic reality is an illusion of the macroscopic world. I know speculation is not liked in this forum, but it is evident that the classic idea of...

    I Wheeler's delayed choice doesn't change the past

    Maybe this kind of "pruning" coincides with Hawking top-down approach, and both remember to me something similar to an "Anthropic Principle". I want to quote Hawking's argument about his application of Feynman sum to the entire universe, two chapters later (pages 135, 136, 140). «If the origin...

    I Wheeler's delayed choice doesn't change the past

    Maybe Mlodinow wrote that. Here is the book, check pages 82-83 https://goo.gl/images/Z6N9gr.

    I Wheeler's delayed choice doesn't change the past

    Thank you Hendrick and Hrvoje. I couldn't fully understand your papers either they were both in Italian or English, but - after your replies - I believe Hawking is exaggerating in telling us (page 83): «...the Universe doesn't have just a single history, but every possible history, each with its...

    I Wheeler's delayed choice doesn't change the past

    I'm delightfully reading the Grand Design by Hawking-Mlodinow. After many years, I became persuaded from it that Feynman's interpretation as multiple paths of interference patterns in the double slit experiment and, more generally, his path integral approach to quantum mechanics, are superior to...
