熵加速宇宙

Entropic Accelerating Universe

Damien A. Easson, Paul H. Frampton, George F. Smoot

摘要:

为了适应观测到的宇宙加速膨胀,一个流行的想法是在Friedmann-Lemaitre暗能量方程中调用一个驱动项,该驱动项必须包含当前宇宙学能量密度的70%。我们提出了另一种解释,它考虑到熵和温度固有的宇宙视界由于全息存储在那里的信息。因此消除了暗能量,并且加速是由于从水平表面屏幕上的信息存储自然产生的熵力。我们考虑了一个额外的定量方法的启发,表面项在广义相对论,并表明,这导致熵加速宇宙。

英文摘要:

To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaitre equation of dark energy which must then comprise 70% of the present cosmological energy density. We propose an alternative interpretation which takes into account the entropy and temperature intrinsic to the horizon of the universe due to the information holographically stored there. Dark energy is thereby obviated and the acceleration is due to an entropic force naturally arising from the information storage on the horizon surface screen. We consider an additional quantitative approach inspired by surface terms in general relativity and show that this leads to the entropic accelerating universe.
