Based upon a simple vacuum Lagrangian, comprising cosmological and quadratic scalar field terms, a cosmological model is presented whose history is indistinguishable from that of an innocuous low-density cold dark matter (CDM) universe, but whose future is very much shorter. For sensible values of the deceleration parameter (0 < q 0 < 1), its age is greater than 85% of the Hubble time, thus res...
