spinors

(It would require new field physics (dark spinors, I think they are called) to explain this possibility.)

The pair of spinors or the twistor constructs a manifold according to its projective structure, which defines light cones and so forth.

A twistor is a pair of spinors well what's a spinor?

The ellipsis involves derivatives of the other spinors and delta functions etc.

Dark Matter: Still Dark.

Since bivectors give you Lie algebras, you get gauge-group-type things, and you might think of spinors as fermions, and think of the vector space as spacetime, and even try to put such things together to form Lagrangians … and see where Einstein-type faith might lead.

One way to see this is that a supersymmetric extension of Yang-Mills theory must have two component spinors, valued in one of these algebras.

Why 10 or 11?

Another way to see this is that the supersymmetry charge is fermionic and this is generated by two component spinors that transform under a representation of SL (2, A).

Why 10 or 11?

This point of view puts connections, spinors and the Dirac operator in central roles in modern geometry, and I happen to think it is a very deep and amazing fact that the same constructs are among the fundamental constructs of the standard model.

Not Even Wrong

{Q, Q} = 2H and the existence of Killing vectors coming from Killing spinors is the same.

The rotational symmetry of a theory including spinors heavily depends on the probabilistic nature of quantum mechanics.
