One of the most interesting questions is; among rocky worlds what is the ratio of worlds that are living vs dead?
1:10^x where x is <=12
(assuming a trillion rocky worlds in our Galaxy & at least 1 living).
Probably x>2-3 from early surveys, but is x=4 or 11,12?
V. different far futures for us!
add a skeleton here at some point
