Classical physics and quantum mechanics are already unified by shared mathematical frameworks. So not only is it possible, it's already been done, which is why people expect it to work for gravity as well.
- scotty79 7y agoQuantum mechanics is not so much unified with classical physics as it is more precise description of part of physics that degrades to clasical physics when you adjust parameters to get less detail. Same way GR is more precise description of ANOTHER part of classical physics that reduces to classical physics if you adjust some parameters. There's really no reason that GR should share with quantum model much more math than the simplest mathematical operations. Why unify GR with quantum and not for example fluid dynamics? GR and quantum field theory for me just describe completely different parts of physics. Sure it would be neat to know how world behaves when neither GR nor quantum is sufficient to predict what will happen but I just think it's way more likely that unified theory will be quantum model with relativistic terms not the quantum description of gravity.
