[Fis] Is quantum information the basis of spacetime?

[Bob Logan]

Hello Andrei - I am with you - sharing you sentiment. Information only pertains to living organisms and entails some signals that help them make a choice. A black hole makes no choices - it is ruled by the laws of physics. Abiotic systems have no information. A book is a set of signals that a reader can convert into information if they know the language which the book is written. A book written in Urdu contains no information for me other than this appears to be a set of signals that contains information for a reader in the language in which this book was written. Who reads a black hole. How does it contain information that makes a difference. When we launch a satellite to orbit the earth we do not say that the sun is informing the satellite how to behave. The satellite is just following the laws of physics. It has no choice and so it is not being informed. There are many different forms of information (biotic and Shannon as found in the 2007 paper Propagating Organization: An Inquiry by Kauffman, Logan et al. in Biology and Philosophy 23: 27-45)      so we do not need to complicate things even more by ascribing the laws of physics as the communication of information.

     Dear all, 
I want to comment so called information approach to physics, by speaking with hundreds of leading experts
in quantum foundations, I found that nobody can define rigorously the basic term "information" which is so widely 
used in their theories and discussions, the answers are as "information is the basic entity" which cannot be defined 
in other terms. Well, my impression is that without novel understanding and definition of information all these "theories" 
are practically empty, well very good mathematical exercises. May be I am too critical... But I spent so much time by trying 
to understand what people are talking about. The output is ZERO.

all the best, andrei

John:
The article describes very really the conflicting attitudes. Interesting to see the diverse arguments together.
I agree, some think so, some do not. I do the latter, but this does not make any matter.

Apparently some physicists think so.
