The time resolution and high etendue of LSST will revolutionize studies of a wide variety of astrophysical phenomena. The umbrella of time domain science with LSST encompasses objects both familiar and exotic, from classical variables within our Galaxy to explosive cosmological events. Within our Galaxy, LSST observations of variable stars will allow the mapping of the stellar halo in new detail, determination of the global Galactic cool star flare rate, and detection of rare evolved binary populations. Beyond the Milky Way, LSST will probe the distant Universe for the most luminous events. LSST will make localization for gravity wave events possible, identify counterparts to GRBs and X-ray flashes, and discover new supernovae. Increased sample sizes of known-but-rare observational phenomena will quantify their distributions for the first time, thus challenging existing theory. Perhaps most excitingly, LSST will provide the opportunity to sample previously untouched regions of parameter space, where transient events are expected on theoretical grounds, but have not yet been observed. In this talk, I will highlight some of the interesting scientific possibilities LSST will bring to transient and variable star science, as well as the challenges we face and opportunities for community involvement.
