Eternally accelerating universe without event horizon
Increasing astronomical evidence indicates that the expansion of the universe
is accelerating. By simply solving Einstein equations we show in this letter
that a wide class of generic quintessence models leading to eternal
acceleration is associated with spacetime static metrics which do not exhibit
future event horizons, and therefore do not pose the same problems for string
theory as asymptotic de Sitter space.Comment: 10 pages, LaTe
