Pillars of Desolation
Rather than being a “stellar nursery” the famous dust
clouds in the Eagle Nebula may have already been destroyed.
On November 2, 1995, NASA released the now-famous image of M16, the
Eagle Nebula, in the constellation Serpens. Jeff Hester, an astronomer from
Arizona State University, was quoted as saying:
"For a long time astronomers have speculated about what processes control the
sizes of stars — about why stars are the sizes that they are. Now in M16 we seem
to be watching at least one such process at work right in front of our eyes."
Star-forming regions within nebular dust clouds have been discussed many times
in
previous Thunderbolts Picture of the Day articles. The prevailing opinion
among astronomers is that stars are created from the collapse of such clouds
through gravitational attraction – the
Nebular Hypothesis. The theory seems plausible because astronomical images
portray what appear to be clouds so dense that they are opaque to visible light
and span tens of light-years. What is not usually mentioned in the press
releases is that the nebulae are composed of gases and dust a thousand times
less dense than a puff of cigarette smoke.
The Hubble Space Telescope photographed the similarly diffuse three pillars in
1995 using its optical sensors, but according to observations by the
Spitzer Space Telescope a shock wave from a nearby supernova may have
already destroyed them. In fact, the Pillars of Creation may have ceased
to exist about 6,000 years ago since there are several candidates for such
explosions scattered throughout nearby space. Because stellar ignition is
dependent on compressive forces, most astronomers conclude that shock waves of
some nature are necessary for the nebular clouds to condense. Supernova blasts
are supposed to provide the impetus needed for the initial collapse and to
“seed” the region with larger granules that will cause more dust to be attracted
to them, as well. Thus, nebulae are deemed “star-forming regions”.
Apparently, Spitzer has confirmed that there is an arc-shaped wavefront of
luminous material moving through the Eagle Nebula. Because of the distance
involved, the infrared radiation being emitted from the shell of expanding gas
is visible as it was 2000 years ago, so in “real time” it has already impacted
the Pillars. The visible-light from the supernova might have been seen on Earth
about that time as a “new star” in the night sky.
Conventional theory suggests that the compression wave from the supernova as we
see it now will both destroy the cloud formations in M16 and begin the process
of star birth from the ashes of their destruction. But, has science actually
increased knowledge with theories such as these? Or has it spun an elaborate
tale based on the slimmest of evidence? The birth and death of stars is
illustrated in such stories of gravity and inertia, but they are missing key
ingredients that provide continuity to the plot. Where is electricity and the
electromagnetic wave guides needed to conduct the current? Both are ignored. How
does the heated gas collapse instead of dissipate, as thermodynamic physics
would insist?
The Electric Universe theory relates a more reasonable account. Instead of “hot
gas and compressed dust”, it is plasma and magnetic fields that form the
electric stars. How does this work?
Birkeland currents power and shape the galaxy and are constricted by the
magnetic fields they generate. Hot gases and dust are prevented from dispersing
inside their multi-light-year-long helical coils. When the current density
inside the twisted filaments gets high enough the plasma that carries the
current begins to glow and to “pinch” into plasmoids that eventually become the
stars.
When the electrical stress is low and the plasma contains a lower concentration
of dust, only the star "lights up" in arc-mode discharge. Where the electrical
stress is greater, as in the Eagle Nebula, disks, jets, and the surrounding gas
clouds can also light up. Of course, dust clouds can reflect the light from
nearby stars, but these glowing plasma formations show the characteristic
filaments and cell-like behavior seen in plasma computer simulations.
