Sudden future singularities

By John D. Barrow. 2004

302 citations recorded by the source corpus.

We show that a singularity can occur at a finite future time in an expanding Friedmann universe even when ? > 0 and ? + 3p > 0. Explicit examples are constructed and a simple condition is given which can be used to eliminate behaviour of this sort if it is judged to be unphysical.

Born–Infeld inspired modifications of gravity (2017, background): “At this respect, some models predict the existence of future singularities that can be broadly classified according to the divergence of some cosmological quantity (see for instance [52, 262, 126, 93, 160, 81, 62, 11] for some related literature).”
Necessary and sufficient conditions for big bangs, bounces, crunches, rips, sudden singularities and extremality events (2005, background): “§ Until quite recently the only FRW cosmological singularities receiving significant attention were the big bang (and its timereversed partner, the big crunch) where a(t) → 0.”
