宇宙模型 meaning in English
cosmological model
Examples
- Tired - light model
光线老化宇宙模型 - Einstein s original cosmological model , introduced by him in 1917 , was a static , homogeneous model with spherical geometry
爱恩斯坦在1917年发表的宇宙模型是一个静态均匀及具有球状对称的宇宙。 - Even if our universe is inhomogeneous , the homogeneity principle can still serve us as simplified model to work with
无论如何，均匀性原理大大简化了我们的宇宙模型，让我们无须迷失于复杂的运算中。 - With these assumptions , we can build a simple model on the universe . we do not expect these assumptions are fully satisfied in reality , but by comparing the model and the real universe , we can learn how and why the real one differs
凭此，我们才能建立一个简单的宇宙模型，当然它不能百分百准确描述我们的宇宙，但只要比较模型和真实之间的差异，我们便可逐渐得知问题出在哪里。 - The gravitational effect of matter caused acceleration and an unstable universe , which einstein did not want , since at the time the universe was not known to be expanding . thus einstein introduced a cosmological constant into his equations for general relativity . this term acts to counteract the gravitational pull of matter , and so it has been described as an anti - gravity effect
当时科学家并不知道宇宙正在膨胀，所以爱恩斯坦对这样的宇宙模型并不满意，故特意在广义相对论引力方程中加入一个人工的宇宙常数，这个常数的作用，相等于一个和引力相反的排斥力，以抵销引力的作用。
