Cluster Collisions
When high temperatures
showed up between two clusters, out came the only tool in
the toolbox to explain it--another collision in an expanding
universe.
In the Big Bang
universe, where everything has been exploding apart for 13
billion years, it’s amazing how many things are bumping into
each other. Astronomers have only one force to work
with—gravity—which works by attraction. So whenever an
energetic event is found, like the high temperature in the
above galaxy clusters, it must have been caused by a
gravity-driven collision.
The researcher
quoted in the BBC report of this finding was puzzled. This
was the first time the clusters were studied in x-ray
wavelengths. Previous studies in visible light seemed to
show two serene, undisturbed galaxy clusters. Yet the x-ray
study shows a very hot temperature (70 million degrees) at
the interface between the two clusters. Why should that be?
Astronomers
consider plasma to be an ionized gas that behaves according
to the same laws that a neutral gas follows, with some
modification for magnetic effects. Because they cannot
directly measure the properties of extragalactic space, they
have developed mathematical models based on the behavior of
neutral gases.
Hannes Alfvén,
the father of plasma cosmology, took a different approach.
In the opening to his monograph, Cosmic Plasma, he
describes how the pure theory approach lost touch with
reality. Rather than theorize about how plasma is supposed
to act, he studied how it actually behaves in the
laboratory. Among the many differences between plasma’s
actual behavior and the theoretical model are temperature
anomalies like the one in the galaxy clusters above:
temperatures of ions and electrons are 10 to 100 times
higher than expected in neutral gases. So, from an Electric
Universe point of view, the anomalous temperature seen in
the above galaxy clusters are a normal property of the
plasma interaction between clusters.
The BBC article
goes on to mention that our own Milky Way, along with our
Local Cluster, is headed for a collision with the enormous
Virgo Cluster a few billion years down the road. If Halton
Arp’s observations are correct, this simply isn’t true. The
apparent collision course is another distortion caused by
astronomers’ failure to account for an age-related component
to redshift. The Virgo cluster is simply older than the
Milky Way: It may be the Milky Way’s parent.
