It's not that we can't model gravity at planetary-orbit scales; that's been done. The issue is that relativity (which addresses gravity) is a good model at large scales and the quantum "Standard Model" (which addresses the other three forces) is a good model at small scales, but these two models are incompatible with each other and no falsifiable theory that works at all scales has yet been found.
- Koshkin 7y agoThey cannot be "incompatible with each other," otherwise Nature would be "incompatible" with itself.
- bobcostas55 7y agoModels are not nature.
- tsimionescu 7y agoThe models are incompatible with each other, which means that one or both are somehow wrong, or there is some boundary we can't fathom between the small scale and the large.
- Koshkin 7y agoWrong - we do know that the models are not incompatible. (There exists a consistent mathematical framework that includes both.) Me, I was referring to a simpler fact that these models are both pretty damn close to what Nature itself tells us.
