第五维空间的暗能量

Dark Energy From Fifth Dimension

H. Alavirad, N. Riazi

摘要:

暗能量存在的观测证据是强有力的。在这里,我们提出了一个模型,它是基于一个修改后的引力理论在5D和解释的第五维作为一个表现的暗能量在4D可观察的宇宙。我们还得到了一个随时间变化的状态方程参数。最后,我们通过选择模型的自由参数将模型与观测值匹配。

英文摘要:

Observational evidence for the existence of dark energy is strong. Here we suggest a model which is based on a modified gravitational theory in 5D and interpret the 5th dimension as a manifestation of dark energy in the 4D observable universe. We also obtain an equation of state parameter which varies with time. Finally, we match our model with observations by choosing the free parameters of the model.
