The rings of Saturn are 73,000,000 meters from closest to farthest from
Saturn. That is, about 20,000,000,000,000,000 square meters of surface
area, or roughly 400 times the surface area of the earth.
The rings of Saturn are five to fifteen meters thick. Not kilometers.
Meters. Like, "here, bring me that ladder..."
This is fun:

Watch the first three minutes at least for the humor as he gets the
crowd warmed up, even if you're not interested in space flight.

Or, roughly, if I did the math right, if saturn's rings were "paper
thin", the piece of paper you cut the rings from would be 1600 meters on
a side, or roughly a mile across.

I very much like the TED site. My only complaint is that there are so
many interesting talks that I spend too much time there.

Except that, AFAIK, Saturn's rings aren't solid. They're composed of rubble.

Yep. Nevertheless mind boggling. I wonder if they're denser or looser
than the paper would be at the same scale? :-)

I use Miro. They have TED channels. I've subscribed to them and set
them to autodownload for every new video that they put up. Usually watch
one while eating or when really bored.
Some are great. Look up the Cameron Sinclair talk. Soon after watching
that, I just happened to see a poster about him - he was giving a talk
near where I live. Was even more impressive when he could talk for 90
minutes.
(Only reason I remembered and noticed his name is that I used to have a
ZX Spectrum when I was a kid).

I think animal testing is a terrible idea. They get all nervous and give
the wrong answers.
