Hi Chaps,

I came across a reference a while back (I forget where) which said that
the average distances between stars is much greater in proportion to
their size than is the distance between galaxies in proportion to
_their_ size. I'm interested to find out what are the actual average
distances between stars, and similarly for galaxies, and also the
mean size of stars and the mean size of galaxies ?

Hint. You can find this for yourself with minimum effort by using the
Web or another marvellous invention - a book.

As this is my first post of 2007, Happy New Year to all!
