Why are early galaxies so strangely compact?
Early Galaxies show a much larger mass-star content ratio than we do
inside our local universe.
Are these galaxies more massive (by more dark matter?) or does their
gravity efficiency change, (by dark energy content)
Stars in a distant galaxy NGC 1097, move at stunning speeds — greater
than 1 million mph, astronomers have revealed. (space.com – Wed Aug 5,
2009,1:16 pm ET)
These hyperactive stars move at about twice the speed of our sun
through the Milky Way, because their host galaxy is very massive, yet
strangely compact. The scene, which has theorists baffled, is 11
billion light-years away.
Given its distance of 11 billion light-years, galaxy 1255-0 is seen as
it existed 11 billion years ago, less than 3 billion years after the
theoretical Big Bang.
Something wrong?
Somehow, galaxies from the young universe grow in size but not in
mass– they spread out but maintain their overall heft – to become the
high-mass full sized galaxies we see today.
In my perspective, there are two options:
Are these galaxies more massive (by more dark matter?) or does their
gravity efficiency change, (by a larger dark energy content)
If Higgs vacuum particles are able to change into matter and
radiation, then matter is concentrated space, then we may presume that
the gravity efficiency in decreasing over time after the big bang,
because the local dark energy content (or Higgs energy) is decreasing.
In other words, the Planck length is shorter in the early universe and
the vacuum as a result is more dense and energetic in its pushing
force on fermions (see Le Sage gravity theory).
Reason to accept that the shorter Planck length is also the origin of
the Hubble redshift.
As a result we are living in a cyclic bouncing universe!
