Nothing for Branes

Abstract
Recent work on closed string tachyon condensation suggests the existence of a `nothing state' where closed strings and space itself vanish. We consider the evolution of D-branes in such backgrounds, focusing on the early stages of the condensation process. We find evidence that the branes exist in the region; although, generically their apparent mass grows exponentially with time. However, there exist specific branes whose boundary states are unaltered by the tachyon.
