On just four short webpages, a simple symmetry principle is described, which leads to a redshift of light and the phenomenon of gravitation, with omega(m) = 0.25, as in WMAP. It also matches the supernovae data without the need for dark energy.

In this model not only is space expanding, but the size
of material objects is increasing too. The size of people, atoms, stars,
distance between all objects - all these lengths increase
uniformly according to

For a rescaling universe which also appears static, it must
be that all physical quantities and constants rescale too.
The size of atoms depends on Plancks constant, so for atoms
to expand it is necessary that Plancks constant rescales too.
The table shows the changes necessary for a rescaling. The
variation depends on the number of length dimensions in the
physical quantity. For example, Plancks constant has metres
squared for its length dimension.
