Spiral Galaxies from a ``Dark Matter'' Solution of Einstein's Equations

We will describe how the structure of all the Hubble classes of spiral galaxies, comprising 75 percent of all observed galaxies, derives from a new geometry related to Big-Bang cosmology. The geometry is an exact 5-D solution of Einstein's equations that induces Dark Matter in a 4-D Poincare`-Schwarzschild ``bubble'' metric. The most visible effect of Dark Matter is the control of structure in the universe. The theory explains unique galactic features including polar rings around galaxies, ``integral'' and ``banana'' warped polar rings, ``reverse rotating'' galaxies, warped galaxies and the scaling of galactic evolution. The presentation will focus on solutions for the structures fitted to observed galaxies.
