What would the world be like if the Principle of Least Action were different? Let's say that it minimized a different quantity than KE - PE.
EF Taylor et al argue that if the quantity minimized were KE + PE, physical systems would accelerate apart from one another. Here's their short articlet; they reach this conclusion about a third of the way through (147-149): http://www.eftaylor.com/pub/ForceEnergyPredictMotion.pdf
What if PLA minimized KE/PE or KE * PE? What would the world look like in each case?
(Of course, some people think the PLA is just a neat formalism. I'm not one of them.)
