Something outside observable universe pulling galaxies

Cosmologists have discovered that 700 clusters of galaxies are being pulled by a massive gravity source that is outside the observable universe.

Since the universe is approximately 13.7 billion years old we can see no more than about 13.7 billion light years in any direction.  However, the entirety of the universe is larger—potentially unimaginably larger—than that due to an early expansionary phase in the universe in which space itself expanded at an incredible rate.  The mass that is pulling on those galaxy clusters, each of which is made up of many galaxies, lies beyond our event horizon, outside the observable universe.

Some of the researchers hypothesize that the mega mass in question is the result of an area of the universe that did not undergo as extensive a period of hyper inflation, leading to a more dense area of space.

In these regions, space-time might be very different, and likely doesn’t contain stars and galaxies (which only formed because of the particular density pattern of mass in our bubble).

It could include giant, massive structures much larger than anything in our own observable universe. These structures are what researchers suspect are tugging on the galaxy clusters, causing the dark flow.

“The structures responsible for this motion have been pushed so far away by inflation, I would guesstimate they may be hundreds of billions of light years away, that we cannot see even with the deepest telescopes because the light emitted there could not have reached us in the age of the universe,” Kashlinsky said in a telephone interview. “Most likely to create such a coherent flow they would have to be some very strange structures, maybe some warped space time. But this is just pure speculation.”

Needless to say, scientists are very surprised at this unexpected finding.

Sarah Palin, the press, and proximity to Russia

The 0.22% of Americans who live in Alaska are (probably) all closer to this than you are. Are they all more qualified to be Vice President?

The 0.22% of Americans who live in Alaska are (probably) all closer to this than you are. Are they all more qualified to be Vice President?

The Obama campaign reports that Joe Biden has given approximately 89 local and national interviews since his selection as the Democratic Vice Presidential candidate. Sarah Palin has given just three meaningful interviews. Apparently to quiet media criticism about this secrecy, today she met with a few of the media who travel with her—after informing them just 20 minutes in advance; she took just four (4) questions in that brief session (read transcript).

Howard Kurtz, a Washington Post and CNN media critic, said “I have never seen a presidential or vice presidential nominee, in my lifetime, be so inaccessible to the national media.” The protection from the press that she’s getting is incredible, as I blogged yesterday. But it’s easy to see why this is: she’s not doing very well in real interviews with well-prepared journalists and needs to be shielded from them. Sarah Palin is not ready for prime time, let alone the Vice Presidency of the United States of America.

I thought that Palin had given up on claiming that Alaska’s proximity to Russia gave her foreign policy experience, but when Katie Couric brought it up in an interview Palin didn’t back down (see video, read transcript). Couric asked what Palin meant when she cited the nearness of Russia as part of her foreign policy experience.

PALIN: That Alaska has a very narrow maritime border between a foreign country, Russia, and, on our other side, the land-boundary that we have with Canada. It’s funny that a comment like that was kinda made to … I don’t know, you know … reporters.

COURIC: Mocked?

PALIN: Yeah, mocked, I guess that’s the word, yeah.

COURIC: Well, explain to me why that enhances your foreign-policy credentials.

PALIN: Well, it certainly does, because our, our next-door neighbors are foreign countries, there in the state that I am the executive of.

Though she couldn’t give any specifics concerning how she’s interacted with Russia (saying something vague about trade missions was the closest she came) Palin still claims that living near a foreign country is somehow a qualification to be the second highest ranking person in our government. Yes, governors do interact with other countries; but Palin needs to build her case on the specifics of those interactions, not by pointing to a map and saying “see how close we are?”

The nominee didn’t do much better on the economic questions that Couric asked. I don’t get the sense that there is a real deep understanding of the issues under Palin’s answers; she sounds like she’s just regurgitating the talking points. Here’s a short clip:

I feel sorry for Joe Biden. How do you prepare to debate someone like this without looking patronizing or like a bully? Especially given that she’s a woman and he’s quite prone to gaffes, as I blogged previously.

On viewing those interview clips, one Slate blogger said “She cannot possibly be this uninformed. You absolutely have to see these for yourself to believe them. These are self-mocking; they could be SNL appearances. Tina Fey couldn’t possibly improve on this. This is why they’ve been keeping her under wraps.” Yep.
