WebHilbert considered general relativity as an essential part of the foundation of physics. [11] [12] However, quantum field theory is not logically consistent with general relativity, indicating the need for a still-unknown theory of quantum gravity, where the semantics of physics is expected to play a central role. [13] Web4.1 The Einstein-Hilbert Action All our fundamental theories of physics are described by action principles. Gravity is no di↵erent. Furthermore, the straight-jacket of di↵erential geometry places enormous ... that there are some situations in general relativity where we should not be quite so cavalier. In such circumstances, one can be more ...

Since we'd like to have creation and annihilation operators, we are actually looking for a Fock space. Since Fock spaces have the form F = C ⊕ H ⊕ ( H ⊗ H) ⊕ ⋯, we pretty much just need to build H. There is a cool trick to do it: we must first get some adequate vector space. can calcium be absorbed through the skin
