暗能量的起源:暗能量是宇宙学核能的结果

Genesis of Dark Energy: Dark Energy as a Consequence of Cosmological Nuclear Energy

R. C. Gupta

摘要:

最近对Ia型超新星的观测和物质(包括暗物质)的低密度测量表明,当今宇宙主要由具有负压的排斥引力型外来物质组成,通常被称为暗能量。但神秘的是关于暗能量的性质和它令人困惑的问题,如为什么,如何,在哪里和何时关于暗能量是耐人寻味的。本文试图在揭示暗能量起源的同时回答这些问题,并提出宇宙核束缚能是在原始核合成过程中释放出来的,在宇宙中长期被束缚,然后自由释放出来的,表现为宇宙中的暗能量。这也解释了为什么对于暗能量,参数w = -2/3。注意,对于刚性物质,w =+1;对于辐射,w=+1/3;对于暗能量,w =-2/3,因为-1是由于缺乏刚性核物质,而这种结合能最终作为辐射释放,贡献+1/3,使得w = -1 + 1/3 = -2/3。这几乎解决了负压和排斥引力的暗能量之谜。得出暗能量是宇宙自由核能释放的结果。所提出的理论进行了几个估计/预测,这与天体物理学的约束和观测相当吻合。

英文摘要:

Recent observations on Type-Ia supernovae and low density measurement of matter (including dark matter) suggest that the present day universe consists mainly of repulsive-gravity type exotic-matter with negative-pressure often referred as dark-energy. But the mystery is about the nature of dark-energy and its puzzling questions such as why, how, where & when about the dark- energy are intriguing. In the present paper the author attempts to answer these questions while making an effort to reveal the genesis of dark-energy, and suggests that the cosmological nuclear-binding-energy liberated during primordial nucleo-synthesis remains trapped for long time and then is released free which manifests itself as dark-energy in the universe. It is also explained why for dark energy the parameter w = -2/3. Noting that w=+1for stiff matter and w=+1/3 for radiation; w = - 2/3 is for dark energy, because -1 is due to deficiency of stiff-nuclear-matter and that this binding energy is ultimately released as radiation contributing +1/3, making w = -1 + 1/3 = -2/3. This thus almost solves the dark-energy mystery of negative-pressure & repulsive-gravity. It is concluded that dark-energy is a consequence of released-free nuclear-energy of cosmos. The proposed theory makes several estimates / predictions, which agree reasonably well with the astrophysical constraints & observations.
