thermal history of the visible worldage of the UniverseWhen the Universe expands the temperature of its medium is decreasing. This is the basic assumption for the thermal history of the Universe reported in [1]. In this paper, we propose a stepwise method for calculating the lifetime of the...
Current observations of the fraction of dark energy and a lower limit on its tension, coupled with an assumption of the non-convexity of the dark energy potential, are used to derive a lower limit of 26 billion years for the future age of the universe. C
We show that this description is in good accordance with the empirical distribution of numerical data and with the problems related to estimating the lifetime of the Universe. 展开 会议名称: IEEE International Conference on Fuzzy Systems 主办单位: IEEE ...

Lifetime, a concept as vast as the universe itself, encapsulates the entirety of one's existence from birth to death. It embodies the experiences, the memories, the lessons learned, and the legacy left behind. As we journey through life, we are constantly confronted with choices, challenges,...
If the radiative decay lifetime τ of massive neutrinos is less than 10 25 s, but exceeding present constraints, the epoch of neutral hydrogen in the history of the universe could have been short or altogether absent. Erasure of small scale fluctuations in the cosmic microwave background ...
