The diagonal method is built assuming that, if two figure sequences like r = 0.a₁a₂a₃... and t = 0.b₁b₂b₃..., for some n satisfy the inequality aₙ ≠ bₙ, then r ≠ t. However, this is only true...

Notice that the well-known gravitational field of Sun M/d^2 works fine when calculating planet orbits. At d=0 the field becomes infinite. It is a singular point. However, we know that at d = 0 by...
