Galactic Interactions

Starting a new blog

Since this blog has shut down (and, really, after this post there will be no more new posts here), I’ve started up a new blog whose focus will be slightly different. Go check out my new blog, Second Sight, if you are at all interested.

(I know I’m not doing this any more, but I couldn’t resist.) An article in New Scientist reports on musing by two reasonable and respected cosmologists— indeed, ones whom I’ve met myself— that our discovery of dark energy may have shortened the life of the Universe. To which I can only say “foo”. And I…

UPDATE : memory hole *not* coming

My overlords at scienceblogs.com have informed me that they will, in fact, maintain the archives of Galactic Interactions indefinitely. Thanks to them! They are really a class outfit.

Note: warning of impending memory hole

My Seed overlords have let me know that as I have decided to no longer continue this blog, I won’t be able to keep the backlogs here indefinitely. Sometime in the next couple of months, the archives will disappear from this site. I also plan to take down the archives from the blog’s former site,…

Blog going on indefinite hiatus

I am going to take a break from astronomy blogging for an indefinite period of time. I’m finding that as I’m involved in my new job, while I still do get a charge out of posts like the Big Bang post I did the other day, my heart isn’t 100% in this. Also, after the…

Fine. The post is deleted already.

If a festering wound exists somewhere, just try to get away. Don’t try to point it out. Especially if it’s not your problem any more. Choose your battles,…

An hour or so ago I heard

Supernovae: the source of cosmic rays

Astronomers have long assumed that supernovae are the source of at least most of the cosmic rays that hit Earth. Woah, slow down… cosmic rays? Right, you hear the term all the time, but do you really know what they are? They are charged particles that rain down on Earth from space. Really! Kinda cool,…

There are days when I want to stand on the rooftops and scream like Zuska. I’m no longer in academia, but as those who are longtime readers of my blog know, I became painfully aware of how sexist the culture of Physics is and how amazingly unequal the playing field is for women— not just,…

If you listened to Science Friday on NPR’s Talk of the Nation today, you may have heard Ira Flatow mention a question from “Prospero Linden”— that was me. I was there, live, along with a 30 or 40 other people in the studio audience: For the last several weeks, Science Friday has been simulcasting over…
