Even better, they are
seeing the universe I expect to see informed by my Cloud Cosmology model. A foundational protocol will naturally spell
out only one possible outcome hugely limiting options in interpretation and
possible observations. As I have posted before,
I have seen my approach stand now for many years.
It is wonderful to see
it fall into place and to find no obvious conflicts.
This is very good
news. We can now see the earliest of the
earliest in expansion behavior. At least
they are calling it an Inflation model and tip toing away from the Big Bang
meme. I concur heartily.

NEW YORK—The universe was born almost 14 billion
years ago, exploding into existence in an event called the Big Bang. Now
researchers say they’ve spotted evidence that a split-second later, the
expansion of the cosmos began with a powerful jump-start.
Experts called the discovery a major advance if
confirmed by others. Although many scientists already believed that initial,
extremely rapid growth spurt happened, finding this evidence has been a key
goal in the study of the universe. Researchers reported Monday that they did it
by peering into the faint light that remains from the Big Bang.
If verified, the discovery “gives us a window on
the universe at the very beginning,” when it was far less than one-trillionth
of a second old, said theoretical physicist Lawrence Krauss of Arizona State
University, who was not involved in the work.
“It’s just amazing,” he said. “You can see back
to the beginning of time.”
Another outside expert, physicist Alan Guth of
the Massachusetts Institute of Technology, said the finding already suggests
that some ideas about the rapid expansion of the universe can be ruled out.
Right after the Big Bang, the universe was a hot
soup of particles. It took about 380,000 years to cool enough that the
particles could form atoms, then stars and galaxies. Billions of years later,
planets formed from gas and dust that were orbiting stars. The universe has
continued to spread out.
Krauss said he thinks the new finding could rank
with the greatest discoveries about the universe over the last 25 years, such
as the Nobel prize-winning discovery that the universe’s expansion is
accelerating.
The new results were announced by a
collaboration that includes researchers from the Harvard-Smithsonian Center for
Astrophysics, the University of Minnesota, Stanford University, the California
Institute of Technology and NASA’s Jet Propulsion Laboratory. The team plans to
submit its results to a scientific journal this week, said its leader, John
Kovac of Harvard.
For their research, astronomers scanned about 2
per cent of the sky for three years with a telescope at the South Pole, chosen
for its very dry air to aid in the observations.
They were looking for a specific pattern in
light waves within the faint microwave glow left over from the Big Bang. The
pattern has long been considered evidence of the rapid growth spurt, known as
inflation. Kovac called it “the smoking gun signature of inflation.”
The scientists say the light-wave pattern was
caused by gravitational waves, which are ripples in the interweaving of space
and time that sprawls through the universe. If confirmed, the new work would be
the first detection of such waves from the birth of the universe, which have
been called the first tremors of the Big Bang.
Krauss and other experts said the results must
be verified by other observations, a standard caveat in science.
Marc Kamionkowski, a theoretical physicist at
Johns Hopkins University who didn’t participate in the work, called the
detection of the light-wave pattern “huge news” for the study of the cosmos.
“It’s not every day you wake up and learn something completely new
about the early universe,” he said.
