DARK ENERGY AND THE PREPOSTEROUS UNIVERSE |
DARK ENERGY AND THE PREPOSTEROUS UNIVERSE
Sean M. Carroll
http://nedwww.ipac.caltech.edu/level5/March01/Carroll/frames.html
http://arxiv.org/pdf/astro-ph/0107571
Abstract. A brief review is offered of the theoretical background concerning
dark energy: what is required by observations, what sort of models are being
considered, and how they fit into particle physics and gravitation. Contribution
to the SNAP (SuperNova Acceleration Probe) Yellow Book.

It will be interesting to see how this pans out.
In contrast, Process Physics offers a radically different
interpretation.

As argued elsewhere [2,3,7] one interpretation is that space is a
quantum system undergoing classicalisation, and at a deep substratum
level has the characteristics of a quantum foam; such an ongoing
`quantum collapse’ would explain why the gravitational field g is
instantaneous from (5) and (8). This quantum foam is in differential
motion, and the inhomogeneities and time dependencies of this motion
cause accelerations which we know of as gravity. This motion is not
motion of something through a geometrical space, but an ongoing
restructuring of that quantum foam. One theory for this quantum foam
arises in an information-theoretic formulation of reality known as
Process Physics, in which all of reality is relational or internal
information, so that in particular space itself is an information
pattern, and one implication there is that the quantum-foam system
undergoes exponential growth in a process of self-organisation, once
the size of the quantum-foam system dominates over the matter part of
the universe. This effect then appears to explain what is known as the
`dark energy' effect, although of course it is not an energy at all,
just as `dark matter’ is not a form of matter.
