When it was first introduced, >50% of Harvard pre-med students taking their required physics course failed a basic concept inventory test given at the end of the semester. (0:28:00) Most had been getting by through the rote application of recipes to generate numerical answers to set problem types. To them Newtonian mechanics remained a black box that had little impact on their underlying modes of thought. Their professor characterizes their view of the world as still Aristotelian.
Now, how many of you out there feel up to a round of advanced placement high school physics? Most of the Harvard pre-meds would have taken and scored very well in their AP physics. And yet they had really absorbed none of it.
Now consider the leap represented by Einstein’s general relativity, which took him a rather painful decade to formulate after his deceptively simple breakthrough with special relativity. He required tensor calculus, which he claimed to understand only at moments when he had exceptional clarity of mind (for him!).
(... and I am glossing over the reformulation of Newtonian mechanics into classical Hamiltonian mechanics, a topic I never got formally exposed to as a mere engineering student…)
I submit if your conceptual understanding of the world hasn’t yet fully encompassed Newton, then “spit balling” ideas regarding black holes is pretty futile.
