Now we know that the internal space of the standard model has a non-commutative geometry, it seems strange that the space-time itself is merely a commutative geometry. Is this just a limit of a more general description of space-time that is non-commutative? Some questions emerge:
- What is a good definition of Lorentzian NCG?
- How can space-time be deformed to such NC structures?
- Is there any evidence in physics for NC spacetime?
