In an earlier post I argued that the nature of science is such that it cannot demonstrate an entity/event to be uncaused, and thus scientific discoveries can never inveigh against the causal premise (“whatever begins to exist has a cause”) of the kalam cosmological argument (KCA) for God’s existence.  Here I want to extend the discussion to the cosmological premise (“the universe began to exist”) of the KCA as well.

The contrapositive of the second premise is “the universe is eternal.”  The nature of science, however, renders it incapable of demonstrating the universe to be eternal even if the universe were eternal.  Why?  Science is an empirical discipline based on what can be observed and quantified.  For science to prove that the universe is eternal, it would have to do so empirically.  But this is impossible.  An eternal past cannot be observed or quantified.
