Spin as Primordial Self-Referential Process
... As already discussed earlier, spin is deeply connected to the microscopic structure of spacetime as reflected by the Dirac equation for fermions (Dirac, 1928). Indeed, Penrose (1960 & 1967) had considered early on that spin might be more fundamental than spacetime and invented spinor and twistor alg ...
