Query: Nonconservation of Energy and Loss of Determinism II: Colliding with an
  Open Set   An actual infinity of colliding balls can be in a configuration in which the
laws of mechanics lead to logical inconsistency. It is argued that one should
therefore limit the domain of these laws to a finite, or only a potentially
infinite number of elements. With this restriction indeterminism, energy
non-conservation and (creatio ex nihilo) no longer occur. A numerical analysis
of finite systems of colliding balls is given, and the asymptotic behavior that
corresponds to the potentially infinite system is inferred.
