If you’re curious about dark energy, check out this short video giving a high-level overview of what dark energy is (well, at least what we know about it, that is…we don’t really KNOW what it is), and how scientists are working to learn more about it.  There’s also a great FAQ on the subject at Discover Magazine’s website…it’s really long, but then, dark energy is a complicated subject!
