**N-body problem** ** ****05/22/16**

Earlier, we have discussed the effects of universal gravitational and how in a classical Newtonian framework a gravitational force acts upon all masses equal to FG=GM1*M2r2. Now, this makes calculations for two isolated interacting objects very simple, but what about more complex systems such as three or more astral objects? The attempt to discern a general equation for such a complexity is known as the **N-body problem**. Physicists have been trying to solve this conundrum ever since Sir Isaac Newton published the *Principia Mathematica*. Supposedly, the equations are even more difficult to solve when one factors in **Einstein’s theory of relativity!**
