> it’s two separate physicists and two separate theories about different areas of physics. They're both touching on consciousness. Wheeler's participatory universe (least several paras of the article) & Penrose's (& coauthor's) microtubules. Penrose was (just days ago) on Theory of Everything talking about whether consciousness affects observation: https://www.youtube.com/watch?v=HPH-SzWF46w&t=83s (tl;dw: he doesn't…

In that video, Penrose explicitly claims that quantum mechanics "is wrong". He means that the equations of quantum mechanics are not sufficient to describe the universe. He thinks you need some additional mechanics to cause wave function collapse. Wheeler, on the other hand, does not claim that quantum mechanics is wrong or incomplete, but suggests an interpretation of the equations. So in my mind they are taking ver…

My recollection of Penrose's quoting in that video is that he said 'Physics collapses the wavefunction' implying he believes it is not a consciousness phenomenon.

No I agree. But in Penrose's thought experiment, he considers the consequences of theories in which consciousness causes an objective collapse.

Seriously, this article brings to mind the classic short story about a simulated universe: https://qntm.org/responsibility And also the wildly speculative conjecture that our universe will be retroactively created by a super intelligent AI in the precise manner necessary to facilitate its own existence, from which it follows that we exist for the express purpose of creating it. (If anybody knows the source I might ha…

There is zero chance this is what you meant, but I wrote a short story with that concept in 2013: https://www.3delement.com/?p=309

Did you end up finding what you were referring to? None of the other comments actually match that
