Dark Matter – Livetweeting

Hello everyone, and greetings from not so sunny Baltimore. I’m down here to attend the Space Telescope Symposium on Dark Matter. I thought it would be fun to livetweet the conference, so if you’re not already following me on twitter, there’s no time like the present. I’ll try to get at least a thought or two out per talk. If there are any particularly exciting results announced, I may also do a few blog posts.

And while we’re on the topic, I figured that for this week’s “Ask a Physicist” column, I’d do something dark matter oriented. The question will be:

Given the tremendous numbers of planets that we are starting to observe in the galaxy: isn’t it possible that the “missing mass” of the galaxy (and the universe) is actually because alien species have built a huge number of Dyson spheres?

which has an extra special sci-fi angle to it. As always, if any of you have fun title suggestions or bonus sub-questions that you think I should address, please let me know in the comments section below.

-Dave
