The price for this is that the algebra of smooth functions on space-time has to be made noncommutative. The generalized differential geometry of space-time is constructed in terms of the algebra A (and its derivations) on a transformation groupoid. Regular representation {\\pi} of A in the algebra of bounded operators on a bundle of Hilbert spaces leads to the algebra \\pi(A) = M_0 which can be completed to the von Neumann algebra M .
