I don't have a preference as to how GR and QM are united, why would I? I certainly do not prefer a rank amateurs feeble attempt. I do not mean any disrespect with that comment - any attempt I made would be the same. I know just enough physics to understand the absolute absurdity of trying. You believe incorrectly since the very beginning of string theory is only about 60 years old. Really? I find that fairly amazing that anyone with an interest in physics would not know that there is no Grand Unified Theory.
