On Earth, natural science had already divorced philosophy.
The essence of philosophy lies in the overarching grasp of "the world." However, the clarity with which one can see the world still depends on how advanced science is, and how far the theories have progressed. Russell once said that any given science, once knowledge about it could possibly be confirmed, would no longer be called philosophy but would become an independent science.
Hence, philosophical systems laboriously constructed by philosophers to accommodate the entire known world would always be shattered by the advancement of scientific theories and breakthroughs. This held true for even the greatest philosophers without exception.
Yet, mathematics, hailed as the "queen of sciences," was an exception.
