This statement is false dipsh6t. Einstein introduced the constant to accord with his theory of a static universe. My speculation about his reasons for doing so is based on his personal writings and the knowledge that he knew an expanding universe, of which their was evidence at the time, implied a creation event.
None of that makes your statement any more correct. In fact introducing a constant to "make the equations come out properly" because the general relativity equation pointed elsewhere isn't science, it's metaphysics.
Got it shmuck?
