Based upon a simple vacuum Lagrangian, comprising cosmological and quadratic scalar field terms, a cosmological model is presented the history of which is indistinguishable from that of an innocuous low‐density cold dark matter (CDM) universe, but the future of which is very much shorter. For sensible values of the deceleration parameter (0< q 0 <1), its age is greater than 85 per cent of the Hubble time, thus resolving the current version of the age crisis, which appears to be that t 0 ∼1/ H 0 while q 0 is significantly positive.
