  We show why and how Compton wavelength and Schwarzschild radius should be
combined into one single new length scale, which we call the
Compton-Schwarzschild length. Doing so offers a resolution of the black hole
information loss paradox, and suggests Planck mass remnant black holes as
candidates for dark matter. It also compels us to introduce torsion, and
identify the Dirac field with a complex torsion field. Dirac equation, and
Einstein equations, are shown to be mutually dual limiting cases of an
underlying gravitation theory which involves the Compton-Schwarzschild length
scale, and includes a complex torsion field.
