_Survey of the nearby universe maps the distribution of about 75,000
galaxies (small blue dots). The placement of each galaxy in the radial
direction is proportional to its distance from the Earth (which is
located at the intersection of the two wedges), and its angular position
(or right ascension in hours of arc) corresponds to its location along a
thin strip in the sky. The galaxies clearly trace a network of
filamentary structures.

The Norwegian, Kristian Birkeland,
in the early 1900s set up an electromagnetic observatory inside the
Arctic circle. He associated the magnetic effects of aurorae with
electric currents flowing between the Sun and the Earth. His electrical
“Terrella” or “little Earth” experiments were able to reproduce the
features of aurorae, sunspots, comets, etc. The BIG LESSON from the
Terella experiments is that they required EXTERNAL ELECTRICAL
POWER GENERATED SOME DISTANCE AWAY. In recent years his name has been
applied to the electric currents discovered in space—“Birkeland
currents.”
The Nobel Prize winning Hannes Alfvén
was trained as an electrical engineer but went on to produce much of
the theoretical underpinning of electrical behavior in the Electric
Universe. An article about his work with the title “Alfvén’s Electric
Universe” appeared in the Boston Globe on Monday, March 20, 1989. Alfvén
insisted that it was of prime importance to understand cosmic
circuitry. But astronomers ignored him.
So discoveries about lightning and auroras continue to surprise
physicists even in this space age. Perhaps there is a good reason for
this. Our Earthly experience is one of solids, liquids and gases. The
region we inhabit between the ionosphere, some 80km above us, and the
surface of the Earth, is one of the rarest environments in the universe.
We inhabit part of the .001% or less of the universe where plasma is
not to be found naturally except in the lightning bolt and occasional
aurora. Plasma has been termed ‘the fourth state of matter’ but in view
of its ubiquity it would be better termed ‘the fundamental state of
matter.’
It is a state where neutral atoms are mixed with charged particles,
positive and negative. These particles may be as small as electrons and
protons or may range up to the size of molecules and dust particles. In a
gaseous plasma, like we find throughout the universe, the charged
particles respond more strongly to electromagnetic forces than they do
to mechanical or gravitational forces. One of the results we see in
lightning is the constriction of electric currents to form long
filaments. And the filamentary nature of plasma in space is well
documented. No dark matter, sprinkled where required to save a theory,
is necessary.
The Electric Universe assumes that Nature is not wilfully hiding her
secrets. The complexity we observe in the universe comes from very
simple electrical principles, some of which can be tested with very
simple apparatus. Science is open to everyone. The visible universe is
an electrical phenomenon, from the structure of subatomic particles to
the superclusters of galaxies in deep space.
The Electric Universe model is simple enough that it can be taught
to young children, but it first requires that cosmology is actually
included in the science curriculum and then treated with a reasonable
level of importance (the subject of a forthcoming article). For the
more mature student, the science curriculum should include studying the
behaviour of electricity in gases. Everyone is familiar with lightning.
Most have seen fluorescent and neon lights. And the writhing “life-like”
filaments in the novelty ‘plasma ball’ are a favorite with kids. But
familiarity with lightning and neon lights does not equate with
understanding. Lightning and the plasma behavior inside those glass
tubes and balls are a mystery to almost everyone. Yet the environment
inside those objects most closely equates to that of the rest of the
universe.
The outgoing president of the International Astronomical Union (IAU) 2009, Catherine Cesarsky, said recently, “I
think young scientists should guard themselves against brainwashing.
They should look beyond the road maps, even if we put the best we know
in them. Also, they should resist specializing too much at the cost of
the big picture. The best way to escape [the] bandwagon effect is to
look at things from a distance, to connect different ideas.”
It is time for another idea in astronomy. The Electric Universe is a
new ‘big picture’ of the universe that “looks at things from a distance
and connects different ideas.” If science has become ‘show biz,’ the
broad panorama of the Electric Universe is fitted for an Imax theatre
show like nothing else before it. The Electric Universe releases us from
the confining eggshell of big bang metaphysics and propels us into the
real universe. Our future depends on it. The possible scientific,
technological and cultural advances will be, as Arthur C. Clarke so ably
expressed it, “indistinguishable from magic.”
