振荡宇宙、暗能量与广义相对论

Oscillatory Universe, dark energy and general relativity

Partha Pratim Ghosh, Saibal Ray, A. A. Usmani, Utpal Mukhopadhyay

摘要:

振荡宇宙的概念似乎是现实的,并隐藏在动态暗能量状态方程中。我们在广义相对论的框架下探讨它的演化历史。我们观察到,对于这样的状态方程,振荡不会被忽视,并且它们的影响在宇宙演化的后期持续存在。“经典的”广义相对论似乎以标度因子增加的形式保留了振荡宇宙的过去历史,而经典热力学则以宇宙学熵增加的形式保留了这一历史。

英文摘要:

The concept of oscillatory Universe appears to be realistic and buried in the dynamic dark energy equation of state. We explore its evolutionary history under the frame work of general relativity. We observe that oscillations do not go unnoticed with such an equation of state and that their effects persist later on in cosmic evolution. The `classical' general relativity seems to retain the past history of oscillatory Universe in the form of increasing scale factor as the classical thermodynamics retains this history in the form of increasing cosmological entropy.
