Tachyon cosmology, supernovae data and the Big Brake singularity
We compare the existing observational data on type Ia supernovae with the evolutions of the Universe predicted by a one-parameter family of tachyon models which we have introduced recently. Among the set of the trajectories of the model which are compatible with the data there is a consistent subset...
