Neat shows on NatGeo. I really got a grip on a couple of things. First, an atom is like the nucleus the size of fly in the middle of a huge chirch or hall, with electrons spinning around the walls. Mostly space.
Fill up a large football stadium with peas, and that how many galaxies there are. Next, take 100 billion football stadiums filled with peas, and that how many stars there are. Next, take 300 billion football stadiums filled with peas, and there must be that many planets, at least. Next I took something like .0000001, or Perhaps % of some kind of life, times the result, and I get a result I can't even deal with..
