It had turned out that Hooke, with his telescope project, had had much more on his mind than countering the ravings of some pedantic Jesuit. Sitting in the dark hole of Gresham's College, marking down the coordinates of various stars, he'd outlined the rudiments of a larger theory to Daniel: first that all cœlestial bodies attracted all others within their sphere of influence, by means of some gravitating power; second that all bodies put into motion moved forward in a straight line unless acted upon by some effectual power; third that the attractive power became more powerful as the body wrought upon came nearer to the center.
