Changes

#:Relativity does not promise uniformity of the universe any more strongly than classical physics did.  The apparent change in mass of the standard kilogram is simply a mystery.

#:The cited article is about speculation that the constant "alpha" (see item 16 above) may not be constant.  It might have decreased, by 45 parts per billion, as recently (in cosmic time) as two billion years ago, based on data from the Oklo "natural fission reactor".  Other measurements have been made of alpha at earlier times, such as measurement of light from distant quasars.  These measurements suggest that alpha has increased by a few parts per 10⁵ in 12 billion years.

#:There is plenty of literature on theories about change in alpha, and some of it indicates that this may be due to change in the speed of light.  Specifically, the Oklo data may suggest that the speed of light may have been increasing slightly.  (This is the opposite of the direction of change claimed by fundamentalists, but is much smaller in any case.)

#:Speculation on a different speed of light in the past may relate to theories of "cosmic inflation", which touches on the question of why the Cosmic Background Radiation is so nearly isotropic, which indicates a near-uniformity of temperature, which requires inflation or some equivalent mechanism.

#:The cited article is about a very recent and exciting development in fundamental theoretical physics, generally called the "holographic principle".  This proposes that our perceived 3-dimensional space actually arises from a "hologram" on a 2-dimensional space.  Much has been written about this recently, including the best-selling book ''The Hidden Reality'' by Brian Greene.  This hologram manifests itself in the "foamlike" ripples of spacetime, at the scale of the Planck length, which is so small that there seemed to be no way to detect it directly.

#:But it seems that some "inexplicable static" in the results of another unrelated experiment, searching for gravitational waves, may be the first hints of the holographic nature of space.  If so, this is a lucky and serendipitous result.
