In such a view, only the interactions between twistors, or perhaps gravitons, define when and where space-time is and is not.
Surprisingly, string theory, Ashtekar's loopy space-time, and twistors are not entirely independent ways of looking at space-time.
Are virtual particles, compact 6-dimensional manifolds, and twistors simply nonphysical means to an end - mere artifacts of how we humans do our mathematics?

The invariance symmetry associated with an 8D Phase Space leads naturally to the real Clifford algebra Cl(2, 6,R) and complexified Clifford [Cl.sub.C] (4) algebra related to Twistors. The consequences of Mach's principle of inertia within the context of Born's Dual Phase Space Relativity Principle were also studied in  and they were compatible with the Eddington-Dirac large numbers coincidence and with the observed values of the anomalous Galileo-Pioneer acceleration.
The connection to Penrose's Twistors program is another interesting project worthy of investigation.
The chief rival to M-theory, albeit having fewer disciples, is twistor
