Duh? Of course -- why is this a surprise? Where would infinite  
precision come from? Why would physicists expect that continuous  
functions explain it all. Robert Laughlin’s A Different Universe  
anticipates some of this.

(Do you have a URL for the original – my comments here are based on  
the basic idea but I’d like to know more about what lead Hogan to  
discover reality LJ)

This is exactly what should be the case as I argue that evolution is a  
digital process (digital as a measure not just 1 vs 0) with DNA being  
a special case that we make a big deal about.

If you look at a book like Leonard Mlodinow’s The Drunkard’s Walk or  
the old systems dynamics models (as in Club of Rome from the 70’s)  
they all become brown mush after a few iterations. Only “digital” can  
be sustained because the can capture the nuance of what works and  
slough off failed niches. This operates at scale and in various  
dimensions. We have minerals, bodies, organs, cells, and DNA because,  
well, what’s the alternative? And if we have one big eco-niche as we  
now do in finance then the mechanism of sloughing it off is decidedly  
problematic.

If I weren’t diverted by the immediate problem shifting from analog  
telecom to digital connectivity I’d work on what I started in http://frankston.com/?name=ESF 
. It’s just another face of the same thing as I discovered following  
up from http://frankston.com/?name=BeyondComputing.

Hi Dave

Perhaps for I.P.

"According to Craig Hogan, a physicist at the Fermilab particle
physics lab in
Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of
space-time -
the point where space-time stops behaving like the smooth continuum
Einstein
described and instead dissolves into "grains", just as a newspaper
photograph
dissolves into dots as you zoom in. "It looks like GEO600 is being
buffeted by the
microscopic quantum convulsions of space-time," says Hogan.

"If this doesn't blow your socks off, then Hogan, who has just been
appointed
director of Fermilab's Center for Particle Astrophysics, has an even
bigger shock in
store: "If the GEO600 result is what I suspect it is, then we are all
living in a
giant cosmic hologram.""


O.K. my scientifically inclined friends.  I give up.  What's goin' on
here?

Cheers,
Bob

Our world may be a giant hologram

    * 15 January 2009 by Marcus Chown
    * Magazine issue 2691.

DRIVING through the countryside south of Hanover, it would be easy to
miss the
GEO600 experiment. From the outside, it doesn't look much: in the
corner of a field
stands an assortment of boxy temporary buildings, from which two long
trenches
emerge, at a right angle to each other, covered with corrugated iron.
Underneath the
metal sheets, however, lies a detector that stretches for 600 metres.

For the past seven years, this German set-up has been looking for
gravitational
waves - ripples in space-time thrown off by super-dense astronomical
objects such as
neutron stars and black holes. GEO600 has not detected any
gravitational waves so
far, but it might inadvertently have made the most important discovery
in physics
for half a century.
