Addendum to "Getting Perspective"

At the end of the video on my previous post, there is a comparison made that if the earth were the size of a grain of sand, then the Milky Way galaxy would be the size of New Jersey. Naturally, I wanted to see how many atoms each human being would represent if living upon the grain of sand. This mental exercise was stopped dead cold...

There are about 70 million, million, million atoms in a grain of sand!! Or "only" about 23 million, million, million molecules. Immediately after that revelation, I saw flashes of light and noted an odd, burning odor. Yep, I hurt my brain.

So that was the smell of something burning I detected earlier. :) That is an amazing video.
