Scientific paper

N-body simulations have been executed to explain the high velocities of IC 342, Maffei 1 relative to the Local Group and to examine how the configuration of four massive bodies (M 31, Milky Way, IC 342, and Maffei 1) might arise, and to study the implications for the mass of local dark matter and the age of the universe. We use our new understanding of the history of the Local Group to study the age of the universe. We modify the Kahn-Woltjer timing argument to suit the more complex dynamical evolution. The most likely value for the age of the universe is about 19 billion years.
