A little more
interesting detail about the presumed earliest light and the apparent
explanation. We have gathered a great
deal of data and largely linked it to our expansion model of the universe’s genesis. This also conforms to my own cloud cosmology
that also must display a primordial expansion although that is now at a creep
due to the power of the inverse of time as it approaches empirical infinity.
This is all good.
The interesting problem
is to assemble the dozens of derivative conjectures that now comprise our
current cosmology and show that they are internally consistant with my Cloud Cosmology. It truly demands a team approach.
Light from Early
Universe Has a Twist
By by
Megan Gannon,
Researchers
have discovered a subtle twist in the primeval light that formed shortly after
the universe came into being. They hope it can reveal new secrets about the
moments after the Big Bang.
This
afterglow, called Cosmic
Microwave Background, or CMB, was created out of hot ionized plasma some
13.7 billion years ago, when the universe was just 380,000 years old. A small fraction
of this light is polarized (meaning the light waves vibrate in one plane).
Researchers
had already detected this polarized light in one pattern, known as
"electric" or E-mode polarization. But using the South Pole Telescope
in Antarctica and the European Space Agency's (ESA) Herschel space observatory,
researchers for the first time detected polarized light from the CMB in the
"magnetic" or B-mode.
The
observed B-mode pattern arose from gravitational lensing, in which light gets
bent and deflected by massive cosmic objects such as galaxy clusters and lumps
of mysterious dark matter, researchers said.
But
there is another way to produce B-modes as well: primordial gravitational waves
produced during the earliest moments of the universe, when it was in its rapid
"inflation" phase, mere trillionths of a second after the Big
Bang.
During
inflation, the idea goes, the universe expanded faster than the speed of light, doubling
in size 100 times or more in just a few tiny fractions of a second. (Einstein's
theory of special relativity holds that no information or matter can travel
faster than light through space, but this rule does not apply to inflation,
which was an expansion of space itself.)
The
new detection should provide a sort of baseline that will aid future efforts to
measure B-modes produced by gravitational waves, which in turn could reveal a
great deal about how our universe grew in its earliest moments, researchers
said.
"This
measurement was made possible by a clever and unique combination of
ground-based observations from the South Pole Telescope — which measured the
light from the Big Bang — with space-based observations from Herschel, which is
sensitive to the galaxies that trace the dark matter which caused the
gravitational lensing," Herschel researcher Joaquin Vieira, of the
California Institute of Technology and the University of Illinois at
Urbana-Champaign, explained in a statement.
The
research was detailed in the journal Physical Review letters, and an early
version of the paper can be found on the preprint site Arxiv.
