For denspressure to be accurate, that would mean all of the math pertaining to a myriad of fields - engineering of aeronautics, architecture, automotive to name a few - would all have to be wrong concerning gravity, motion, and just construction in general. Inertia and momentum, from what I can understand, are explained completely different using denspressure. I may be wrong on that. But regardless, topics regarding gravity have been proven over and over, mathematically and physically.
