  The first phase of stellar evolution in the history of the universe may be
Dark Stars, powered by dark matter heating rather than by fusion. Weakly
interacting massive particles, which are their own antiparticles, can
annihilate and provide an important heat source for the first stars in the the
universe. This talk presents the story of these Dark Stars. We make predictions
that the first stars are very massive ($\sim 800 M_\odot$), cool (6000 K),
bright ($\sim 10^6 L_\odot$), long-lived ($\sim 10^6$ years), and probable
precursors to (otherwise unexplained) supermassive black holes. Later, once the
initial DM fuel runs out and fusion sets in, DM annihilation can predominate
again if the scattering cross section is strong enough, so that a Dark Star is
born again.
