A brief introduction to Gravitational Economics First things first: money follows the law of gravity, by trickling. Just like in Newtonian mechanics, 'down' is the direction of the largest nearby havy object, in moneyspacetime, pieces of money trickle down — towards the largest nearby rich object. At the same time — and this is something that classical econogravyists don't really like to talk about —, the velocity of money is limited by the speed of green light. Which is not even a constant, because an economy is like Tinker Belle — it starts to slowly fade away every time people stop believing in it.
