  Spin networks, spin foams and loop quantum gravity

Loop quantum gravity is a theory that results from the canonical
quantization of general relativity. A covariant (path integral)
formulation of the theory is expected to be in the form of a spin foam
model, such as the Barrett-Crane model. _/*Spin networks are diagrams
which provide a basis for the Hilbert spaces of these theories.*/_
They also describe representation-theoretic computations that are used
in computing amplitudes. This page is a collection of links to
information about loop quantum gravity, spin foams, and spin networks,
with some focus on parts relevant for extracting predictions from the
theory.

I just translated in terms of neutrino chemistry ideas.


Great, but do either the spin network or neutrino chemistry approaches
offer a credible plan to resolve the VED crisis?

To reiterate: the vacuum energy density crisis inolves a 120 order-of-
magnitude discrepancy between the VED of high energy physics and the
VED of cosmology.

The general consensus among professional physicists is that this
humongous discrepancy has never been explained and there are few if
any credible resolutions that have been published in peer-reviewed
scientific literature. Therefore it is a very serious problem which
begs a solution.

I point out that the revised scaling for gravitation predicted by
Discrete Scale Relativity (see Paper #12 in the Selected Papers
section of www.amherst.edu/~rloldershaw , which was published in
Astrophysics and Space Science 311(4), 431-433, October 2007) ofers a
simple and natural way to remove 115 orders-of-magnitude from the
discrepancy. See my initial post for a recap of how it does this. Feel
free to ask for more details specifically related to the DFP
resolution. A paper discussing this potential approach to the VED
crisis is in preparation.

If anyone has an alternative resolution for the VED crisis, I would
like very much like to hear about it. But please make a full and
coherent presentation of the basic arguments and direct me to
published literature that confirms the idea as one that has been
explored scientifically and adequately explained. Name-dropping and
mathematical calculations without adequate physical motivation just
don't take us where we want to go. No one has time to chase after
every random idea that gets mentioned here without adequate empirical
support or scientific motivation. We need clarity, not arm-waving
confusion.
