Subject: Re: First direct evidence of cosmic inflation
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.
Interesting. Could you be more specific why. is it because of the nature of
the signature of these ripples in spacetime.

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:

Harvard-Smithsonian Center for Astrophysics
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.
