The key point is that there are no constants (scalars: real or complex) in nonlinear math. In linear physics there are constants like the speed of light of special relativity, Planck's constant in QM; in nonlinear general relativity, there is no explicit constants although the universal constant of gravity, G, is implied. Dirac used to think that by the principle of extremely large numbers, G is not a constant. If numbers are all very large, it is very difficult to measure which one among them is the largest.

unpredictability.
