First, I want to apologize if I’ve posted this video on here before. I’m currently too lazy to go back through ye olde archives and check (read: I’m too lazy to type “powers of ten” in my little search box), so I’m just going to go with it.

I logged into my older, rarely-used YouTube account today and was looking through my favorites list and I found this video.

I don’t care that it’s from 1977, I don’t care that I’ve watched it like 80 times. It still blows my mind. So I thought I’d share it for this week’s science blog.

Like I said when I posted that other video about the universe a few weeks ago: I don’t know how we could ever feel disconnected from one another when we’re all part of this working machine of huge and small alike.
