A complete description of any interaction requires the complete description of the entirety of the Universe due to non-zero effects of literally every particle or fluctuation, self-interaction of bodies in quantum superposition, Mach's principle and large scale entropic effects. If you're looking for the ultimate truth regarding any information in the Universe, you need a full Universal wavefunction, and the minimum required volume and energy necessary to write it down is, you guessed it: the entirety of the Universe.
So no, we have not one single mathematical model that communicates the absolute truths of Nature because that's not what science does, and as far as we can tell, it's not physically feasible. Science provides extremely accurate models that approximate Nature and allow us to engineer solutions to our problems and increase our capacity to manipulate Nature at will.
Want to know absolute truths? Ask a philosopher.
Want to know absolute truths about the physical world? Get on your knees and pray.
Get out of here with your popsci hatred of things you don't understand.
