The possibilities for Star Wars puns are endless.

There are alternative explanations that theorized that the 2nd law is not linear for extremely weak forces.[1] Thus, two masses that were sufficiently far apart would experience an attraction larger than that predicted by an inverse square law.

I think some particular applications of these theories were proved wrong some years ago, but I can't find those results.
