The Acceleration of the universe, a challenge for string theory
Apr, 2001Citations per year
Abstract:
Recent astronomical observations indicate that the universe is accelerating. We argue that generic quintessence models that accommodate the present day acceleration tend to accelerate eternally. As a consequence the resulting spacetimes exhibit event horizons. Hence, quintessence poses the same problems for string theory as asymptotic de Sitter spaces.- astrophysics: acceleration
