This vid has the most amazing graphics when viewed full-screen in HD. And it discusses "things" that few of us can even begin to comprehend, given the distances and mind-boggling numbers involved.

I find this sort of stuff SO much more enlightening and entertaining than the freaking health-care brouhaha. YMMV, of course.
