The Evolving Universe and the Puzzling Cosmological Parametrs
Arbab I. Arbab
The universe is found to have undergone several phases in which the gravitational constant had different behaviors. During some epochs the energy density of the universe remained c…
A linearly Expanding Universe With Variable G and Lambda
Arbab I. Arbab
We have studied a cosmological model with a cosmological term of the form $Λ=3α\fr{\dot R^2}{R^2}+\bt\fr{\ddot R}{R}+\fr{3γ}{R^2} α, \ \bt γ$ are constants. The scale factor (R) is…
FRW-Type Universe With Vacuum Energy Density
Arbab I. Arbab
We have considered a cosmological model with a cosmological constant of the form $Λ=3α\frac{\dot R^2}{R^2}+\bt\frac{\ddot R}{R} α, \bt=\rm const.$ The cosmological constant is foun…
The Past Earth's Rotation
A. I. Arbab
We have proposed a model to obtain the length of the day and month at any geologic time. The day is found to increase by 0.002 sec/century since the seventeenth century. The length…
