With due consideration of reasonable cosmological assumptions within the limit of the present cosmological scenario, we have analyzed a spherically symmetric metric in 5D setting within the framework of Lyra manifold. The model universe is predicted to be a DE model, dominated by vacuum energy. The model represents an oscillating model, each cycle evolving with a big bang and ending at a big crunch, undergoing a series of bounces. The universe is isotropic and undergoes super-exponential expansion. The value of Hubble’s parameter is measured to be [Formula: see text] which is very close to [Formula: see text], the value estimated by the latest Planck 2018 result. A detailed discussion on the cosmological parameters obtained is also presented with graphs.

一种用于寻找暗能量源的高维宇宙学模型

在当前宇宙学情景的范围内适当考虑合理的宇宙学假设，我们在天琴座流形框架内分析了 5D 环境中的球对称度量。模型宇宙被预测为 DE 模型，以真空能量为主。该模型代表了一个振荡模型，每个周期都以大爆炸的方式演变并以大紧缩结束，经历一系列反弹。宇宙是各向同性的并且经历着超指数膨胀。哈勃参数的测量值是[公式：见文本]，与普朗克2018最新结果估计的[公式：见文本]非常接近。还通过图表详细讨论了获得的宇宙学参数。
