Dynamical Cobordism and the beginning of time: supercritical strings and tachyon condensation

Abstract We describe timelike linear dilaton backgrounds of supercritical string theories as time-dependent Dynamical Cobordisms in string theory, with their spacelike singularity as a boundary defining the beginning of time. We propose and provide compelling evidence that its microscopic interpreta...
