However, we have a system that proves "yes", and and another that proves "no". The former is invaluable in Real Analysis, whereas the latter is useful in Game Theory.

Real Analysis contribute much to Physics via Fluid Dynamics via Boundary Value Theory.
Game Theory/Decision Theory contributes much to Economic Theory.
These are real Scientific Theories. Real Analysis contribute much to Physics via Fluid Dynamics via Boundary Value Theory.
Game Theory/Decision Theory contributes much to Economic Theory.
These are real Scientific Theories.

The Scientists is not concerned about such Settheoretical concerns. However, they are unwittingly grateful that e Mathematician has laid the ground work. That's the black box I spoke of.

It contradicts the results of common arithmetic, but this does not make it "false". It is still consistent and has actual realworld applications.
