Twistor Theory: Evaluating Its Relevance in Modern Unification Theories

[warhammer]

Twistor Theory was once deemed as a viable unifying idea conceptualized by Sir Roger Penrose. However, is it now time to say that the theory is unofficially dead or does the idea still have merit against other unification theories?

From what I've seen, people are still trying to apply it to cutting edge work in LQG and String Theory.

https://www.twistordiagrams.org.uk/papers/index.html"Twistor diagrams for scattering amplitudes have been explored since the early 1970s, when Roger Penrose first wrote them down. But the ideas underlying them suddenly received quite new attention at the end of 2003, when Ed Witten's twistor string model brought together twistor geometry, string theory and scattering amplitudes for pure gauge fields."
