Abstrak

Abstract It is suggested [ astro-ph/0306438 ] that current cosmic acceleration arises due to modification of general relativity by the terms with negative powers of curvature. We argue that time-dependent (hyperbolic) compactifications of (4+ n )-dimensional gravity (string/M-theory) lead to the effective 4d gravity which naturally contains such terms. The same may be achieved in the braneworld by the proper choice of the boundary action. Hence, such a model which seems to eliminate the need for dark energy may have the origin in M-theory.
