In the physical literature about the n-body problem (n 3), sometimes reference is made to the impossibility of solving the n-body problem (via employing the above approach). However, care must be taken when discussing the 'impossibility' of a solution, as *this refers only to the method of first integrals* (compare the theorems by Abel and Galois about the impossibility of solving algebraic equations of degree five or higher by means of formulas only involving roots).
