The interesting question is which cosmogony models are ruled out by this. I think it
rules out the d-brane collision models and maybe other string based models.

Wow. That is so cool, the first (sort-of) direct detection of gravitational waves, as
opposed to infering their existence from binary neutron stars' orbital decay. (This is
kind of parallel to how the neutrino was discovered, come to think of it.)
That pattern looks so regular, like atoms blown up to the size of galaxies... they say
they spent 3 years checking the data for local sources and I can see why, that looks
like a really clear signal. And evidence for inflation, too ... (can they deduce
anything about how it happened, how long for etc, yet?)

First direct evidence of cosmic inflation
Date:
March 17, 2014

Summary:
Almost 14 billion years ago, the universe we inhabit burst into existence
in an
extraordinary event that initiated the Big Bang. In the first fleeting
fraction of a
second, the universe expanded exponentially, stretching far beyond the view
of our
best telescopes. All this, of course, was just theory. Researchers now
announce the
first direct evidence for this cosmic inflation. Their data also represent
the first
images of gravitational waves, or ripples in space-time. These waves have
been
described as the "first tremors of the Big Bang." Finally, the data confirm
a deep
connection between quantum mechanics and general relativity.
