Could I ask you for the relation between Wheeler's ideas and the multiverse? Do you know if these are related?
I ask you this because I found this very interesting article written by Kip Thorne with Wojciech Zurek and Charles W Misner (https://www.its.caltech.edu/~kip/PubScans/VI-50.pdf) where they seem to indicate that Wheeler was a multiverse proponent
For example, at some part of the article they wrote:
"Wheeler described to his two former students his idea that the laws of physics are mutable: Those laws must have come into being in our universe’s Big Bang birth, and surely there are other universes, each with its own set of laws. “What principles determine which laws emerge in our universe and which in another?” he asked"
and also, at the end of it, they wrote
"Wheeler speculated that universes governed by sensible laws could come to be inhabited by observer–participators."
But then I contacted a biographer and analyzer of Wheeler's works and he told me that Wheeler's ideas are completely different to any kind of multiverse and that Wheeler was not happy with the idea of a multiverse.
"There are a few hundred essays that Wheeler wrote from the 70s to the 90s where he built up his ideas. If you can find something in his essays about how his approach to quantum theory is the same as the multiverse approach, I will stand corrected. But I have looked over these for years, and have not seen anything other than his complicated relationship with Hugh Everett's Many Worlds. I have seen many physicists just guess what Wheeler was talking about, without citing anything that he actually wrote When you ask them their source it is usually "Well that is what my colleagues think" and when you ask their colleagues, they were just giving an interpretation of the phrase "it from bit" without reading any of the essays."
Also he cited Wheeler
"Its [MWI/Everett] infinitely many unobservable worlds makes a heavy load of metaphysical baggage."
(He said that His approach (It from Bit) was meant to alleviate this philosophical issue, i.e to eliminate the multiverse in Everett's Interpretation)
So, are Wheeler's ideas and the multiverse compatible or not? Is the biographer that I contacted right? Is Wheeler's "It from Bit"/"Participatory Universe"/"Pregeometry and Law without Law" and the Multiverse related? Apart from this, do you know of any quote of Wheeler that indicates that his ideas are compatible with the idea of a multiverse?
