  One perspective on this might be found in:
Frautschi, S. (1982) “Entropy in an expanding universe”.  Science 217,
593-599.
Frautschi, S. (1988) “Entropy in an expanding universe.” in B.H. Weber, D.J.
Depew  and J.D. Smith, eds.  Entropy, Information and Evolution.
Cambridge, MA: MIT Press.
And
Landsberg, P.T. (1984)  Can entropy and “order” increase together?  Physics
 Letters 102A, 171-173.
And
Layzer, D. 1977. Information in cosmology, physics and biology. International
Journal of Quantum Chemistry 12 (supplement 1) 185-195.

 Basically, in an expanding or growing system much entropy production is
mediated by information AND creates more information while doing it.

[Fis] On the Origin of Gravity and the Laws of Newton

[Steven Ericsson Zenith]

Dear List,

I bring Erik Verlinde's recent paper to your attention because it highlights 
some foundational issues in Information Science and the general use of the 
notion of "Information" in physics.

Here is the paper:

On the Origin of Gravity and the Laws of Newton
http://arxiv.org/abs/1001.0785

The paper has attracted a lot of attention and Lee Smolin's response, also on 
arvix, is really what made me begin to look at this question seriously. Though 
various people have been bringing the paper to my attention since it was first 
published in January.

Verlinde appeals to a notion of an "entropic force" associated with a 
conception of information and frankly I'm puzzled by it. What, exactly, does he 
refer to I wonder and how does it relate to Shannon, if at all? 

My initial view is to suspect that the paper is a work of pure metaphysics and 
not physics at all. But then I ask myself to what degree it is less 
metaphysical than anything else we see in physics today. So I reserve judgement 
until I have given the matter more consideration.

Anyone else concerned by this?

With respect,
Steven
