A couple of links from Day, both which could make you freak out if your that way inclined, each one very differently:
- Powers of 10: from 10 million light years away to 10 attometers away, looking at the same spot.
Another fun thing to think of while watching this is how the map is lying to you — how the dots scale, and so on and so forth.
- Interconnected: a look at how everything is connected to everything.
Day’s a fun guy for this sort of thing. I still remember, soon after meeting him, that he proved to me that some infinities are larger than other infinities. It’s still a head-clutcher for me to this day. He also pointed out to me that the universe is expanding at an ever-increasing rate. Which is oddly soothing: it makes me feel like I’m in the process of exploding, only really slowly, and if I’m lucky, I might die & decompose before I notice the side effects of this fact.
