'So, you don't understand, but you feel sure that GR and QM are incorrect. I can never quite fathom these attitudes.'

I will sum up my position as best I can. I do not believe that ANY theory is COMPLETELY wrong or COMPLETELY right. Or, rather, MY understanding of any theory is never complete enough to hold an absolute position on its validity. If you were to say 'you have some doubt (maybe as small as the planck length) that GR and QM might be wrong in some way', that would possibly be closer to my position. Another way to express it may be to say I have no choice but to accept the MATHEMATICS of GR and QM are correct but do consider the possibility that our interpretation of these maths into visual pictures of warps and black holes and dead/alive cats may not be the best metaphore.

I tend to lean away/toward competing theories depending on what new/different interpreration to the facts I come across, rather than 'believe' in the absolute truth of one theory.

I understand that it must be frustrating when novices like myself post comments that more learned people would probably be embarassed to put their name to. Perhaps you should take the course of action of ignoring any and all posts attributed to me? No need to waste your time trying to improve MY ignorance
