First of all, I would like to point out that I have zero background in general relativity, but due to my overwhelming curiosity I will post this question anyway.
So, what's wrong actually with applying the correspondence principle, which is typical in quantum mechanics, to quantum gravity? Suppose a system of zero charges, why wouldn't the equation
$$
\left(\frac{p^2}{2m}+G\frac{mM}{r}\right)\psi = E\psi
$$
work as it does with the electric potential? Why is the search of a satisfying theory of quantum gravity still on going, what has been impeding the physicists in this field?
