  We introduce a novel approach, a Dense Shell Method (DSM), for measuring
distances for cosmology. It is based on original Baade idea to relate absolute
difference of photospheric radii with photospheric velocity. We demonstrate
that this idea works: the new method does not rely on the Cosmic Distance
Ladder and gives satisfactory results for the most luminous Type IIn
Supernovae. This allows one to make them good primary distance indicators for
cosmology. Fixing correction factors for illustration, we obtain with this
method the median distance of 68^{+19}_{-15} (68%CL) Mpc to SN 2006gy and
median Hubble parameter 79^{+23}_{-17} (68%CL) km/s/Mpc.
