Why we need diferent models to explain the underlying laws of the universe?

To explain the physical phenomena of small scales (10 ^ -35 to 10 ^ -10 meters) we use QM, Hilbert geometry,...

To explain the physical phenomena of large scales (10 ^ 10 to 10 ^ 25 meters) we use GR, Riemann geometry,...

To explain the physical phenomena of normal scales(10 ^ -10 to 10 ^ 10 meters) we use Newton, Euclid geometry,...
