Alternative Models of Reality
Zeeya Merali

If you have an unconventional, alternative model of reality, then this is the place to discuss it. (This is for contributors who have preliminary ideas and would like feedback, but do not have an academic paper or arXiv preprint and have not given a conference talk based on their ideas.) Edited on 31 August to add: Thanks to Peter and John for commenting on my recent Nature article: "The Origins of Time and Space," which surveys some of the recent ideas on reality, and could serve as inspiration for this thread. :-)

Georgina, I just read your notes & comments. Your very wise thoughts on states found not existing until detection go to the root of the Copenhagen interpretation (In extremis; is the moon there when we're not looking?). More sensibly it equates to Von Neumann; "The 'meter' is part of the system" which I've recently found more profound than most have thought. I think you'll like my essay which develops that to it's conclusion. I look forward to yours.

Best

Peter


Hans,

Or even three or more different ways, or aspects of the same phenomena I suggest! I hope you're well, and look forward to catching up with your latest work/ essay.

Peter
