Fortunately, we don't need to completely understand it. New Horizons
reached Pluto right on time after a decade of flight that involved
taking a left turn at Jupiter... we can predict exactly what angle to
fire the rockets at in order to get where we want to go, even without
knowing how that gravity yank works.

Practicality beats purity?
