When the gods are shaken from the sky,
there's a scientific reason why.
There's no wish to replace them
and no-one's rushing in to win
the race to fill the empty space

I've added a page, which I hope to extend over time, of links to reference material which might be relevant or useful.
Any suggestions, comments, etc. can go here (I want to keep comments disabled on that page).
