Why does everyone keep invoking Einstein's name and theory to something he never accepted as even having a reality apart from the math????

"The problem quite naturally leads to the question, answered by this paper in the negative, as to whether physical models are capable of exhibiting such a singularity."
Einstein understood that mathmatical singularities simply meant that the theory was incomplete and missing vital information.

"Physicists are undecided whether the prediction of singularities means that they actually exist (or existed at the start of the Big Bang), or that current knowledge is insufficient to describe what happens at such extreme densities......
Many theories in physics have mathematical singularities of one kind or another. Equations for these physical theories predict that the ball of mass of some quantity becomes infinite or increases without limit.
This is generally a sign for a missing piece in the theory, as in the Ultraviolet Catastrophe, re-normalization, and instability of a hydrogen atom predicted by the Larmor formula."
Einstein tried to tell them he wasn't ready to apply it to the rest of the universe and continued to try to fix his theory until the day he died.....
