Abstract
Based upon a simple vacuum Lagrangian, comprising cosmological and qua dratic scalar field terms, a cosmological model is presented the histo ry 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 res olving the current version of the age crisis, which appears to be that t(0) similar to 1/H-0 while q(0) is significantly positive.
