Let's get back to real /sci/

Why are half these threads about existent/non existent God/Gilgamesh, "omg divide by 0", ".999... =/= 1", racism, and ID/evolution?  Props to the real math threads every once in a while.

Let's get back to real /sci/.

Poll:  Given that quantum mechanics and general relativity are mutually exclusive, which one is right?

QM/QED/Standard model?
GR?
Neither?
String theory?
Something else?

i don't understand why GR and QED can't both be models that we apply on a case-by-case basis.  physiscists do it all the time when they don't have the complete picture.  wave/particle duality?  nuclear physics?

physicists often hodge-podge models together in order to explain things.  i don't see why the same can't be done with GR and QED, since both have been observed.
