As space now permits, the Drake equation mentioned in the intro is:
N* fp ne fI fi fc fL
N* = the number of stars in the Milky Way galaxy (current est 100 billion)
fp = fraction of stars with planets around them
ne = number of planets per star ecologically able to sustain life
fI = fraction of those planets where life actually evolves
fi = the fraction of fI that evolves intelligent life
fc = the fraction of fi that communicates
fL = the fraction of the planet's life during which the communicating civilizations survives
Try it with various figures. Which one will turn out to be Vogsphere I hate to think.

"The Hitchhiker's Guide to the Galaxy is a wholly remarkable book. It has been compiled and recompiled many times and under many different editorships. It contains contributions from countless numbers of travellers and researchers."
