Twistor theory can be applied in complex space-time, particularly useful for quantum theory involving wave functions.

I believe it's possible to unify general relativity and quantum mechanics, as history shows that physics has often moved towards unification, like how Maxwell unified electricity and magnetism.

Twistor theory, which I started in 1963, has had many developments and has spread interest in different areas of physics.

Twistor theory originated from my realization that light rays can be represented by points on a five-dimensional boundary, allowing for a global description of space-time.

The quest for a theory of everything that unifies general relativity and quantum mechanics may not yield a simple equation, as gravity might emerge from quantum phenomena at a macroscopic level.

We haven't unified quantum mechanics and general relativity yet because we don't know what the fundamental objects are, and we need to rethink our notions of space and time.

The concept of twistors introduces a new kind of curved twistor, which is essential for understanding complex solutions in physics, but it also leads to inherent confusion in the theory.

String theory is currently the only theory that has survived scrutiny and attempts to unify the theories of the small and the big in physics.

The strength of geometric algebra lies in its ability to unify various concepts in physics, including quantum mechanics and relativity, potentially offering new insights into quantum gravity.
