  • Anna Fedorova thinks this is interesting:

When making sense of the future, think in terms of gravitational cores, not hard boundaries. Just as the sun’s gravity well reaches out beyond the orbit of Pluto and encompasses not just the planets in the ecliptic but comets and planetoids with eccentric orbits, so too the forces shaping the future all have a gravitational core and a gradually attenuating influence. And just as the solar system has multiple gravitational subsystems, where the draw of the local giant keeps its own satellites in tow while all still partake in the larger dance, these interpenetrating trends influence each other and converge.

This is a great metaphor for the way forces in the economy/society work.
I also like this quote: "Love is metaphysical gravity" -- it's conceptually similar and deeply relevant to societal function.
