And if you do, what sorts of things do you research? Do you only look up the really big things, or the small things too?
I seem to research only really odd things.
My list so far consists of (but is not limited to): potatoes, the great Irish potato famine, the Great Chicago Fire, maglev trains, the history of flight, airplanes, train bombings across the world (especially those in London, New York, & Moscow), clouds, crop circles, & urban legends.
I'm pretty sure my novel is the first thing to combine all of those together.
