The Mass/Time Quotient
Isaac Newton's classical physics has two bodies separated by a certain distance impacting at a certain rate. Newton could not have had a notion of outer space, as we do today, and it's a weakness of his theory. When I first studied Newton's gravity calculations, I amused myself by visualizing in my mind's eye a pair of balls suspended in space, impacting precisely as postulated by Newton. My study of Newton's laws did not prepare me for the modern view of physics -which involves much more than mass. Now, when I imagine two balls in space, they don't impact, but, rather, whirl around one another. Gravity is still in effect. When the two careening bodies reach the furthest possible extent of separation, they return—again and again—until (perhaps) forever. The reason for this ellipsoidal motion is the Three Body Problem. True, only two bodies are involved in my imaginary scenario. Nonetheless, if the Three Body Problem affects three—or more—bodies, it is in effect ...
