I am a first year undergraduate who in my spare time is desperately trying to understand what happens when General Relativity and Quantum Mechanics are 'merged'. Almost all of the searches I have done on the subject have turned up with the same similar statements: 'General Relativity and Quantum Mechanics don't work together' 'The solutions to simple questions give nonsensical answers with infinities' etc. etc. Just very simple statements aimed at the general public. Yet for the rest of the searches, I run into relativity complicated journals aimed at postgraduates such as this: (http://iopscience.iop.org/0264-9381/19/13/312/pdf/0264-9381_19_13_312.pdf free version: http://wenku.baidu.com/view/e0c576d86f1aff00bed51edf.html) Which don't really help me at all. I can't seem to find any journals or textbooks that give an example of these two theories being combined, and that shows the equations that lead to the infinity answers; a middle ground so to speak, between the general public and postgradutes. Here is an example of what I'm trying to find: Michio Kaku goes through the equations from 3:30 to 7:30 in that short clip, unfortunately all the 'good stuff' is just left out. Does anyone know where I could look to find a detailed run through of the equations he is going through in those clips? Any help would be much appreciated.
