A new noncommutative spacetime of structure cal M4 \× Z2 \×\nZ2 is proposed. The generalized Hilbert-Einstein action contains gravity, all\nknown interactions and Higgs field. This theory can also provide a unified\ngeometric framework for multigravity, which might explain the existence of dark\nmatter and inflationary cosmology. In other words, high energy physics has laid\nout the crude shape of the new spacetime, while cosmology will shed light to\nthe more details of it.\n
