| الملخص: | Observations of type Ia supernovae show that the expansion of the universe
is accelerated. Cosmological constant has been taken as the standard solution
to explain this phenomenon. However, cosmological constant suffers from fine
tuning and coincident problems. To solve the problems of the cosmological
constant, several dark energy models have been proposed, such as quintessence,
k-essence, and phantom. However, beside dark energy, there exist another
class of possible solution for the phenomenon of cosmic acceleration, i.e. modified
gravity. This approach alters the natural behaviours of gravity, to develop
solution that can explain observational phenomenons, including cosmic acceleration. |
