A brief overview of what we know about dark matter, some history of when the idea arose, and current experiments designed to detect or otherwise figure out what dark matter is. This talk was presented in Second Life in February, 2012
Dr. Doherty will answer a selection of questions posted by June 24, 2012.

No. The thing that makes it "dark" is its complete or near complete lack of interaction with ordinary matter via any forces except gravity. Assuming it is, in fact, made of of non-baryonic particles, it would simply pass through a box made of normal matter- just like it's probably passing through the Earth and our bodies right now.
